This is a magnitude 5.0 earthquake scenario under Lake Ontario, very close to Toronto. This fault is not known to be active but demonstrates a plausible earthquake scenario for Toronto region.

The Beaufort fault in Eastern Vancouver Island is probably an active fault, near Courtenay/Comox/Cumberland. Based on current science, this fault may have ruptured in the 1946 magnitude 7.3 Vancouver Island Earthquake. This scenario represents a smaller magnitude 5.2 event.

Full rupture of the Leech River Fault, a fault that cuts southern Vancouver Island and extends beneath Greater Victoria. Based on current science, this magnitude 7.3 earthquake scenario represents the strongest ground shaking event that could strike the region, and is one of Greater Victoria’s most severe events.

A magnitude 5 earthquake scenario along an unnamed fault located about 15 km north-northeast of Burnaby City Hall and directly south of Mt Elsay. This fault is not known to be active, but this scenario represents a small but damaging event in the North Shore Mountains.

This is a magnitude 5.0 earthquake scenario along the Burlington Toronto Structural Zone — a fault near Toronto and its surrounding region. This fault is not known to be active but demonstrates a plausible earthquake scenario for the Toronto region.

In September 1732 a damaging earthquake occurred immediately beneath the Island of Montréal. This scenario visualizes the effects of that event if it occurred today with a magnitude of 5.0, and represents a strong ground shaking event that could strike Montréal.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia, near Vancouver. This scenario visualizes the effects of that event if it occurred today with a magnitude of 5.0. A magnitude 7.0 Georgia Strait scenario is also provided, and represents a less likely but more consequential case for comparison.

A magnitude 5.9 earthquake near Montreal, along the Milles-Îles Fault. This fault is not known to be active, but this scenario represents a small but damaging event near the City of Montreal.

The National Earthquake Scenario Catalogue, presents the probable shaking, damage, loss and consequences from hypothetical earthquakes that could impact Canadians. It considers only damage to buildings, and their inhabitants, from earthquake shaking, and therefore does not include damage to critical infrastructure or vehicles. Losses from secondary hazards, such as aftershocks, liquefaction, landslides, or fire following are also not currently included. The information is provided at the approximate scale of Census dissemination areas, and is intended to support planning and emergency management activities in earthquake prone regions. This project is run by the Geological Survey of Canada's Public Safety Geoscience Program.

In 1997, a magnitude 4.6 earthquake occurred 3 to 4 km beneath the Strait of Georgia, near Vancouver. This scenario visualizes the effects of that event if it occurred today with a magnitude of 4.9. A magnitude 7.0 Georgia Strait scenario is also provided, and represents a less likely but more consequential case for comparison.
