| Comments | North York ON, February 21, 1979. The North York Gasoline Leak occurred on the morning of February 21, 1979 at Imperial Oil. The gasoline had escaped from a separator and gone into the sewer system underneath the industrial area bounded by Finch and Sheppard on the north and south and by Keele and Dufferin on the west and east. Estimates of the gasoline that eventually flowed into Dufferin Creek vary between 800 and 2,000 gallons. |
