Volcanoes may seem to be non-existent in Canada. There has been only one documented volcanic eruption in Canada in more-recent historical times, but there are many dormant volcanoes in western Canada, particularly in northwestern British Columbia. The entire western Cordillera (BC-Yukon) remains geologically active. Therefore, the possibility of an eruption, even a large explosive one, cannot be ruled out.
Ash plumes are the major volcanic hazards in Canada
Canada's most significant volcanic risk comes from explosive eruptions in adjacent Washington and Alaska. Prevailing winds would blow the ash into Canada, as has happened in the past. Ash fallout would cause respiratory ailments for people and a hazard to any technology. Ash plumes can also adversely affect air traffic, such as in the 2010 Icelandic volcano eruption.
