Health Canada estimates that 5,900 Canadians die every year from air pollution. [50] A 2008 study by the Canadian Medical Association estimated that almost 3,000 Canadians die annually from short-term exposure to air pollution, while another 18,000 die annually due to long-term effects of polluted air. The study estimated the economic impact of ...
The number of climate change–related events, such as the 2021 British Columbia Floods and an increasing number of forest fires, has become an increasing concern over time. [56] Canada's annual average temperature over land warmed by 1.7 °C (3.1 °F) between 1948 and 2016.
Pollution Probe was founded in 1969 by a group of students and faculty at the University of Toronto out of a desire to address environmental issues. The group initially focused on air pollution and only the Ontario area, but gradually expanded to also focus upon other forms of environmental pollution over time, and also nationwide concerns.

Asthmatic airway versus normal lungs' airway. The Government of Canada estimates that 14,600 premature deaths per year in Canada can be linked to air pollution from fine particulate matter, nitrogen dioxide and ozone, from the report Health Impacts of Air Pollution in Canada – Estimates of Morbidity Outcomes and Premature Mortalities - 2019.

For Ottawa, it was the biggest snowfall since nearly 14 inches (36 cm) fell on February 23, 2003, but fell well short of its all-time snowfall record of 29 inches (74 cm) set on March 2–3, 1947. [ 34 ] [ 40 ] In Quebec City, the 16 inches (41 cm) received in 24 hours were 4 centimeters short of its worst in such a period, the record being the ...
On April 5, a major low-pressure system crossing Lake Superior pushed a warm front toward eastern Ontario and western Quebec while a high-pressure area over eastern Ontario siphoned cold air into the St. Lawrence and Ottawa River Valleys. [2] The mild air aloft ahead of the front produced rain, but the air was below freezing at the surface ...
Tropospheric Emissions: Monitoring of Pollution (TEMPO) is a space-based spectrometer designed to measure air pollution across greater North America at a high resolution and on an hourly basis. [ 4 ] [ 5 ] The ultraviolet–visible spectrometer will provide hourly data on ozone, nitrogen dioxide, and formaldehyde in the atmosphere.
