Annual Review Objective:
Through this Annual Review, the Canadian Conservation Institute (CCI) presents results achieved in 2010–2011 to the Department of Canadian Heritage, to CCI clients and partners in Canada and around the world, and to the Canadian public.
Through its expertise in conservation science, treatment, and preventive conservation, CCI supports the heritage community in conserving Canada's heritage collections so they may be accessible to present and future generations.
To achieve its mission, CCI organizes its operations under three business lines:
- research and development in conservation, including scientific research, advanced techniques for treatment and restoration, and practical and innovative solutions for caring for collections
- equitable provision of expert services to the heritage community in Canada, including scientific services, conservation treatments, and preservation advisory services that meet the community's needs
- dissemination of conservation knowledge, through training, professional development, online learning materials, and publications, to assist professionals, workers, and volunteers in the heritage community in making informed decisions about care of their collections
Meri Karinen (CCI curriculum intern from Finland) is treating the varnish top coat of a medicine wagon. The wagon is a unique local artifact from the Cumberland Heritage Village Museum, Cumberland, Ontario. It was built by J. Dufourd, a local carriage maker in Ottawa during the late 1800s, and owned by Mr. John D. Ferguson, a pharmacist in Cumberland. Ferguson, son of Dr. James Ferguson, used the wagon from circa 1890 to 1910 to sell Stroud's Tea, Spices, and Cordials, as well as his father's patent medicines.
Rémi Catillon (CCI curriculum intern from the Institut National du Patrimoine, France) is removing a white polish residue from a Japanese cabinet. This complex teak and ivory Asian trade cabinet is from Eldon House, London, Ontario, and was collected by the Harris family on an 8-month-long trip to Japan in 1897.

Message from Minister
As Minister of Canadian Heritage and Official Languages, I am pleased to present the 2010–2011 Annual Review of the Canadian Conservation Institute. This review offers a complete overview of all the Institute's achievements and activities and describes how it is responding to the needs of the heritage community all across Canada.
This community—made up of our museums, art galleries, archives, and historic sites–has the mission to protect, restore, display, and transport the treasures of our culture and heritage so that they are accessible to current and future generations. The Institute, which supports the heritage community in this work, is recognized around the world for its technical skill in the science of conservation, in restoration, and in preventive conservation.
I would like to congratulate the Institute and everyone who believes in the importance of promoting our heritage. Your efforts are helping increase our knowledge of Canada, a vast country forged through a history rich in events, acts of bravery, and achievements large and small.
The Honourable James Moore
Director General's Message
The Canadian Conservation Institute's Annual Review for fiscal year 2010–2011 not only reports on our accomplishments but also highlights our work on some of Canada's most significant heritage collections and objects. These objects — concrete examples of Canada's history that reflect the country's diverse heritage — include a beaded pouch made by First Nations in the 1940s and 1950s and a painting by one of Canada's most important artists of the 19th century. In addition to the work done for objects and collections, we also contributed to the preservation of heritage interiors, including an historic house with exceptional 2nd Empire architecture built in 1882–1883, and Canada's Parliament Buildings, arguably the country's most significant heritage buildings. We also continued to address some of the present-day challenges facing Canada's heritage institutions: the preservation of digital heritage assets, and the identification and care of plastics in museum collections.
Examining the statistics, you can see that CCI increased the number of expert services provided to clients in Canada (by 60%) as well as the number of workshops delivered in all provinces and territories. The number of clients in Canada and internationally who have registered for our CCI e-News continued to grow as did the number of participants in our internship program — with 12 interns participating throughout the year, including 5 who came from France, Austria, and the United States as part of their conservation education programs.
Like most government organizations, including the Department of Canadian Heritage, CCI experienced budget reductions. While these exercises are always challenging, they help us focus on priorities such as protecting our ability to deliver conservation and conservation science expertise and services, basing decisions on becoming more effective and efficient, and improving ways to communicate with and disseminate information and advice to our clients. To support client needs, we also began the review and redesign of our website to ensure tools and learning materials are easily accessible, implemented a new approach to strengthen our client inquiry centre, and increased our capacity to gather and analyse business intelligence on the conservation needs of the heritage community in Canada.
Over the next year, CCI will continue to strengthen our professional development program, designing and implementing new workshops and advanced professional development courses. We will also host an international symposium Adhesives and Consolidants for Conservation: Research and Applications in the fall (October 17–21, 2011) to disseminate current practical and theoretical knowledge on the application of adhesives and consolidants in heritage conservation and to highlight CCI's leadership role in this area over the past 30 years.
Conscious of the economic situation, we will explore ways to help museum directors, conservators, and other professionals protect their collections, while reducing the energy costs associated with maintaining a museum environment.
Finally, 2012 represents a significant anniversary for CCI (which was created in 1972), as well as the 200th anniversary of the War of 1812. To mark these events, we will have a special edition of our magazine REFLECTIONS, and will feature the preservation of War of 1812 artifacts.

Research and development highlights
Characterization of Canadian amber: Canada is rich in amber deposits of varying geological age and type. The purpose of this research project was to characterize amber from sites across Canada The ability to distinguish amber from various locations will not only aid in understanding the organic geochemisty of the deposits, but will also be helpful in studying early decorative objects produced by First Nations using these materials. The results of this project will help archaeologists learn more about how this material was used and potentially traded by early Aboriginal peoples.
The chemical composition and maturity of the amber samples were determined using Fourier transform infrared (FTIR) spectroscopy, and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS). CCI scientists Jennifer Poulin and Kate Helwig found three distinct sub-classes in the Canadian amber deposits studied. Additionally, analysis determined that two deposit sites in Nunavut and one site in British Columbia contained a type of amber not described by the existing classification system. This new sub-class of amber is presently unique to Canada, and has been classified as Class Id.
Stability of optical discs and magnetic tapes: Preservation of digital materials has become a critical issue for archives, libraries, and other heritage institutions. This research project aims to determine which optical discs are of good quality and to verify claims made by manufacturers about their products. An important milestone was achieved this year with the completion of the experimental phase on accelerated aging. Experiments on disaster recovery have indicated considerable variability among discs, which may also exist in their longevity. After publishing results on the stability of CDs, CCI scientist Joe Iraci authored an article explaining the results and making recommendations about DVD formats ["The Stability of DVD Optical Disc Formats,” Restaurator vol. 32, no. 1 (March 2011), pp. 39–59].
Accelerated aging of this DVD movie disc resulted in the degradation of the reflective metal layer in the inner portion of the disc. The integrity of this layer is critical for the DVD to be readable.
Accelerated aging of this DVD movie disc under conditions of elevated temperature and relative humidity caused deterioration of the metal layer in the form of circular holes.
Light damage calculator: Balancing the protection of heritage objects and works of art from light damage while enabling them to be seen by museum visitors can be a challenge. CCI conservation scientists Stefan Michalski and Eric Hagan have developed a light damage calculator that estimates colourant fading at a given light dose based on the best available data. This calculator will be available on the CCI website sometime during fiscal year 2011–2012. It will allow users to evaluate light deterioration by selecting colourants, exposure levels, and exposure durations of particular interest; faded colours will be presented as patches on the computer screen. The model will provide light-fading calculations in three different scenarios:
- fading of a single colourant
- fading of a single colourant compared in different scenarios
- fading of a collection of coloured objects
Thank you so much for giving an excellent lecture to my class in the Chemistry of Art and Archaeology. It was quite clear that they enjoyed your lecture and, to judge from the questions at the end, you may have changed some of their career ambitions.
I would like to take a moment to thank you for your excellent lecture at the 2011 Canadian Association for Conservation Conference on the new ASHRAE standards. I was relieved to hear the news of the new standard and its implications. (…) All in all, the news of the new standards came as a welcome relief.

Conservation and Treatment Services
Beaded pouch: The Maisie Hurley Collection comprises objects gifted to Mrs. Maisie Hurley by Aboriginal leaders in British Columbia and elsewhere, during the 1940s and 1950s, in recognition of her advocacy work for Aboriginal rights in Canada. CCI conservators treated a beaded pouch, one of many objects in the collection, now property of the North Vancouver Museum & Archives (NVMA) in North Vancouver, British Columbia. NVMA presented, in partnership with the Squamish Nation, a major new exhibition ("Txwnch7á ṁnew'as kwis eslihikwiws / Entwined Histories: Gifts from the Maisie Hurley Collection”) from January through November, 2011.
The treatment of the beaded pouch necessitated multiple approaches:
- cleaning by dry brushing and vacuuming
- humidifying the leather and fringe, depending on the results of shrinkage temperature measurements
- reshaping the pouch and inserting just enough acid-free tissue to maintain the object's shape without putting stress on the seams
- repairing the tears and securing delaminating areas of the leather
This beaded pouch is one example of the many gifts Maisie Hurley received from the Aboriginal community in recognition for her advocacy work for Aboriginal rights in Canada. Dr. Sharon Fortney, co-curator of the exhibition with Damara Jacobs, explains that the exhibit reveals relationships that continue to be meaningful for the Squamish Nation. "The combined advocacy of the Squamish elders showcased in this exhibit, and non-native supporters, such as Maisie and Tom Hurley, enables the current generation to continue to build collaboration.”
Miniature baby buggy: Object and textile conservators treated a miniature replica of a full-size baby buggy, hand-made by a professional carriage builder and property of the Royal Alberta Museum in Edmonton, Alberta.
The carriage was cleaned using a vacuum, dry brushing, and, where necessary, gentle washing with distilled water and non-ionic detergent. Flaking and lifting paint was consolidated with adhesive. A new wooden dashboard was made and inpainted to match the rest of the carriage, and broken and deformed structural elements were repaired.
The upholstery was vacuumed and dry brushed. Neutral-coloured fabric was also inserted under losses of the fabric on the seat cushion and under losses on the chair arms to reinforce these fragile areas and make them less visible when on display. Padding was inserted along the top of the proper right arm to restore it to its proper shape.

The Great Eastern at Heart's Content: The Great Eastern at Heart's Content is a painting from the archives of the Anglican Cathedral of St. John the Baptist in St. John's, Newfoundland and Labrador (NL). It depicts a pivotal event in Canada's pioneering role in the development of telecommunications technology, i.e. the arrival of the SS Great Eastern, July 27, 1866, at Heart's Content, NL on completion of the laying of the first underwater trans-Atlantic telegraph cable from its starting point in Valencia, Ireland. Fine Arts conservators addressed extensive surface abrasion and losses with retouching and revarnishing in stable, non-yellowing media.
Moccasin Seller Carrying Papoose: CCI's Fine Arts lab treated Moccasin Seller Carrying Papoose, a painting from the collection of the MacKenzie Art Gallery in Regina, Saskatchewan, by nationally renowned 19th-century Canadian artist Cornelius Krieghoff. In 2006, conservation scientists analysed a sample of the cloudy surface coating, which proved to be a co-polymer of methyl methacrylate and n-butyl acrylate — a modern coating. UV examination of the painting revealed that the background sky and part of the foreground had been entirely overpainted in a solvent-sensitive paint. Fine Arts conservators removed the overpaints and surface coating to reveal paint loss as well as a very heavy crack pattern. The decision was made to consolidate and then relax the paint layers and canvas back into plane without flattening the tacking margins. A jig was designed and built by the conservators to carry out this procedure. The painting has been secured to the original stretcher over a transparent solid support that allows the back of the painting to be seen, and to retain, as much as possible, its original characteristics. Some retouching and reintegration were also needed to restore the delicate beauty of Krieghoff's scene to its original appearance.

Burial cloths from Madagascar: A conservation scientist analysed two silk burial cloths from Madagascar (circa 1850–1899), from the collection of the Royal Ontario Museum (ROM) in Toronto, Ontario, to identify the dyes. The cloths both feature vibrant colours and, based on their ages, may contain threads dyed with early synthetic dyes, such as mauveine. Analysis was performed using novel gas chromatograph-mass spectrometry (GC-MS) methodology. Dyes on the first cloth consisted of natural materials including indigo, safflower, turmeric, and tannins. These dyes were used individually and in mixtures to produce the magenta, blue, yellow, purple, burgundy, teal, and black colours of the cloth. Both natural and synthetic dyes were identified on the second cloth. The natural dyes were identified as indigo, turmeric, and tannins, and the synthetic dyes as diamond green (basic green 4), crystal violet (basic violet 3), and erythrosine (acid red 51). The dyes were detected individually and in mixtures on the silk threads to produce the aqua, pink, red, purple, green, blue, yellow, and black colours. Interestingly, both natural and synthetic dyes were detected on some threads. This unusual practice of mixing natural and synthetic dyestuff was likely a product of the dyeing time period, when the earliest vibrant synthetic dyes were being introduced and natural dyes remained in common use.

The akotifahana cloths of Madagascar come into museum collections through estate sales and dealers. Without knowing the specific dates these items were created, and in the absence of stylistic changes through time that would provide an indication of their age, they are extremely difficult to date precisely. Determining whether or not a cloth has natural or man-made dyes is, therefore, crucial for dating. CCI's ability to establish precise dates linked to the invention of certain types of dyes allowed the ROM to pinpoint more exactly the age of this cloth, and aided understanding of other similar collections around the world.
Madagascar Island lies between Africa and Eurasia, and has been at the crossroads of cloth trading for 2 millennia. Knowing the dye sources of this cloth has helped the ROM to pinpoint which nations (India or Arabia) influenced hand weaving on the island and brought them weaving supplies. Having one of the oldest collections of textiles from Madagascar, Canada contributes to these questions and to this field of knowledge.
Malépart de Beaucourt paintings: François Malépart de Beaucourt has been recognized as the first Canadian painter to have developed his technique in Europe. The materials of two of his paintings, one dated 1786 and the other 1787, were studied by CCI's Conservation Science Division. A comparison of the materials was of interest since recent research suggests that they were both painted in Saint Domingue (now Haiti), a location where there would have been a limited supply of artists' materials. The paintings, one in the collection of the Montreal Museum of Fine Arts and the other in the collection of the McCord Museum (both in Montreal, Quebec), were examined and sampled on site. Detailed information about the pigments, media, and layer structure of the paint was obtained. It was found that the materials of the two paintings were very similar.
Survey of public art at the New Brunswick Centennial Building: The Province of New Brunswick is planning extensive renovations to the Centennial Building in Fredericton, which houses the offices of the Province of New Brunswick. The murals, mosaics, metal art assemblages, and wooden relief sculptures were commissioned for Canada's Centennial in 1967, and installed throughout the six-floor building. The artwork was executed by some of Canada's most prominent artists in the 1960s: John Hooper, Claude Roussel, Bruno Bobak, Jack Humphrey, Tom Forrestall, and Fred Ross.
CCI developed a plan to protect these artworks during the rehabilitation of the building. The plan addresses demolition risks, vibration, impact damage, dust and moisture, and changes to the indoor climate during renovations. In consultation with the New Brunswick Art Bank, CCI also provided costing, scope, and a process for the conservation treatment of this important public art collection, prior to Canada's 150th anniversary in 2017.
Relocation of monuments and chandeliers in the West Block of Parliament Hill: The CCI Heritage Interiors team is working with the Parliamentary Precinct Branch of Public Works and Government Services Canada (PWGSC) during the renovations of the West Block (originally called the Western Departmental Building) on Parliament Hill in Ottawa, Ontario, a project that will last through to 2016. Renovations of these buildings will affect many different types of heritage objects, and CCI's expert services will help to ensure these significant heritage collections are protected.
When sculptures of the Right Honourable Sir Robert Borden and the Right Honourable John Diefenbaker were affected by the reconstruction of the West Block, CCI developed a plan to relocate them. By moving these commemorative statues of two former Canadian Prime Ministers to a new location behind the Library of Parliament (instead of moving them to storage as had been planned), they remain accessible to Canadians. The site selection options, soil testing, temporary concrete pad designs, granite plinth and statue relocation, and the hoisting operations were coordinated by CCI with the cooperation of the Parliamentary Precinct Branch of PWGSC and the assistance of professional stonemasons and carpenters.
CCI also worked to protect six monumental Regency-period chandeliers (1844). These chandeliers were originally commissioned for the Royal Assembly Rooms in Liverpool, England. Canada's Department of Public Works in London purchased them for the Confederation Room in the West Block in 1961. When the decision was made to return the Confederation Room to its original purpose, i.e. offices for parliamentarians, CCI disassembled, cleaned, and packed the chandeliers for their safe transport and storage prior to the decommissioning and demolition of the room.

Risk assessment pilot project at Glanmore National Historic Site: Glanmore National Historic Site in Belleville, Ontario, built in 1882–1883, is an exceptional example of 2nd Empire architecture. CCI carried out its first comprehensive risk assessment at this historic house — a pilot project using methodology and tools that have been developed over the past few years in collaboration with the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM), based in Rome, and the Instituut Collectie Nederland (ICN), based in the Netherlands. The key risks to the collection were identified, and their severity was ranked based on the likelihood (or speed) of an event occurring, the loss of value that would result, and the amount of the collection that would be affected. Options were presented for addressing the most important risks, with an indication of their cost and cost-effectiveness. This report has allowed the heritage institution to identify its priorities, and to target those risks that are most likely to cause the greatest loss in collection value.

Silverware in the dining room could eventually lose detail and inscriptions from annual polishing to remove tarnish buildup. Applying a lacquer coating would keep the silver tarnish-free and eliminate the need for regular polishing.
Inuit Heritage Trust Fly-In Conservator Program: Four Inuit Heritage Trust sites in Nunavut (Pond Inlet Archives and Nattinnak Visitor Center in Pond Inlet, and Unikkaarvik Visitors Centre and Nunatta Sunakutaangit Museum in Iqaluit) benefited from CCI's facility assessments and training se
