On Dec. 1, 1962, the Winnipeg Blue Bombers met the Hamilton Tiger-Cats in the 50th Grey Cup at Toronto’s Exhibition Stadium. During the game, a mass of thick fog rolled ashore from Lake Ontario, severely limiting on-field visibility and forcing the CFL to suspend play with less than 10 minutes remaining in the fourth quarter (the game resumed the next day, with a Bombers victory). The moisture from the fog interacted with tailpipe emissions and industrial pollution, producing one of the worst smog episodes in Toronto’s history. For three days, heavy smog blanketed the city, exposing Torontonians to unhealthy air and symbolizing a dark period in Canada’s air quality history.
