Of course Canada has volcanoes!
Would you believe 21 active volcanoes? There have been almost 50 eruptions in the Yukon and British Columbia since the last ice age ended.
However, per experts,
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.
Here is a video from the Royal Tyrrell Museum of Paleontology with more detailed information:
Global Volcanism Program:
- Mount Garibaldi (VEI 3, about 8060 BC)
- Cayley Volcanic Field
- Meager (VEI 5 around 410 BC)
- Tseax River Cone
- Iskut-Unuk River Cones
- Level Mountain (I think this is the same as what Canadians call Volcano Mountain.)
- Edziza (VEI 3 some time in the last 7,000 years)
