[2] On July 14, 2000, at approximately 7 PM, an F3 tornado tore through the Green Acres Campground at Pine Lake in central Alberta, killing 12 people and critically injuring more than 100 others.

The tornado formed out of a severe thunderstorm which formed on the eastern slopes of the Canadian Rockies and moved rapidly eastward, encountering a narrow band of low-level moisture that caused it to develop into a supercell thunderstorm.

Damage assessment suggests that winds within the central corridor reached 300 kilometres per hour (190 mph).

The highest death toll due to a single tornado in Alberta occurred on July 31, 1987, colloquially referred to as Black Friday.

Canada ranks second in the world for tornado occurrences after the United States.
