4905 Dufferin Street
The ECCC building at 4905 Dufferin Street in Toronto, Ontario has served as a focal point for meteorology and atmospheric science in Canada for more than 35 years. It currently houses staff from several areas of ECCC including the Science and Technology Branch, Meteorological Service of Canada and the Canadian Wildlife Service.
This has been the home of a large portion of the Atmospheric Science and Technology Directorate (ASTD) and its predecessors since 1971. Currently, ASTD staff and laboratories engaged in research on air quality, climate change, meteorology and impacts and adaptation, and staff of the Science and Risk Assessment Directorate in atmospheric science assessment and integration are located here. With more than 210 staff, ASTD has the largest staff complement in the building’s total population of approximately 800, including atmospheric physicists and chemists, meteorologists, statisticians, mathematicians, physical geographers, climatologists, science-policy experts and scientific support staff. An important, co-located national research facility is the Andrew Thomson Laboratory for atmospheric chemistry (on the right in the picture above).
Proximity to researchers and facilities at several universities, federal and provincial laboratories and field facilities in southern Ontario has made this area a hub for atmospheric research in Canada.
