At 2059 mountain standard time (MST) on 20 May 1999, Line 3 on the Enbridge Pipelines Inc. (Enbridge) pipeline system ruptured, releasing 3 123 cubic metres (m3) (20,600 barrels) of Cold Lake heavy crude oil. Approximately 3.6 hectares (ha) (8.8 acres) of farmland was affected by crude oil.

The Ochapowace First Nations, whose traditional lands this spill occurred on (this is Treaty 4 land, some consider to be Metis teeeitory), have stated that there were long term environmental and cultural effects that the company chooses not to acknowledge.  Enbridge claims they have “fee simple” to a corridor that is bound “on two sides” by land owned by The Ochapowace First Nations.  Enbridge has stated that, in 2007, the National Energy Board declared that the remediation of the land was completed appropriately.
