Parks Canada Agency Laboratories

Parks Canada, Ottawa, Ontario
What the facility does

Conservation, preventive conservation and analysis of historic objects

Area(s) of Expertise

The Parks Canada Agency Laboratories focus on the study of culture heritage materials which involves their conservation and analysis. The conservation encompasses preventive, remedial and restoration actions that are all completed in our laboratories. These are: monitor and interpret environmental conditions (temperature, relative humidity, light, vibrations, etc.); training and advice to safeguard objects in storage and on exhibit; perform scientific imaging of objects/collections (radiography, 3D laser scanning, infrared (IR) photography, photogrammetry, etc.). A variety of equipment is used to complete the least intrusive, reversible treatments for objects (stabilization, cleaning, freeze dryers, vacuums, sand blasters, etc.); appropriate supports/mounts are built for storage or exhibit purposes; reproductions are created through free hand sculpting, fabrication or moulds for display or interpretive purposes (mixing resins, plasters and/or rubbers). As far as the analysis of works of art and archaeological objects is concerned, the work performed at the laboratory includes the preparation and analysis of samples as well as the interpretation of results collected through analytical instrumentation (Gas chromatography – Mass spectrometry (py-GC/MS), Scanning Electron Microscope - Energy Dispersive X-ray spectroscopy (SEM/EDS), Raman and Fourier Transform Infrared (FTIR) spectroscopies, X-Ray Fluorescence (XRF), microscopy).

Research Services

Providing conservation and analytical services for Parks Canada Agency’s sites for the care of artifacts. Analytical instrumentation is used to identify and characterize cultural heritage materials in order to shed light on their material history and technology of manufacture as well as on their stability and deterioration.
