Volcanoes in Canada: Active, Dormant, and Extinct Peaks of the Pacific Ring of Fire

Canada's Volcanic Landscape: Sleeping Giants of the Cordillera

Canada hosts over 200 potentially active volcanic centers, almost entirely in British Columbia and the Yukon, part of the Pacific Ring of Fire. Most are remote, poorly monitored, and pose localized rather than catastrophic risk.

Notable Volcanic Centers

Volcano / ComplexLocationTypeStatus / Last ActivityKey Features
Mount MeagerBC, Garibaldi Volcanic BeltStratovolcanoPotentially active; last eruption ~2,350 yr BP (Plinian, VEI 4–5, similar to 1980 St. Helens). 2010 massive landslide (50M m³). Monitored (seismic, gas).Closest to Vancouver (150 km). Geothermal potential.
Mount GaribaldiBC, Garibaldi Volcanic BeltComplex stratovolcanoDormant; last eruption ~10,000–13,000 yr BP. Glacially eroded; multiple cones (Atwell, Dalton).Iconic landmark; popular climbing/skiing.
Mount CayleyBC, Garibaldi Volcanic BeltStratovolcanoActive (Holocene); last eruption ~7,000 yr BP. Fumaroles, hot springs. Seismic swarms 2000s.Geothermal target; difficult access.
Castle RockYukon, Northern Cordilleran Volcanic ProvinceAlkaline basalt cinder coneYoung; eruptions ~1,000–2,000 yr BP. Lava flows, tephra.Remote; minimal monitoring.
Mount EdzizaBC, Northern Cordilleran Volcanic ProvinceShield volcano / complexPotentially active; last eruption ~1,300 yr BP. Largest volcanic complex in Canada (1,000 km²). Obsidian source for Indigenous trade.Edziza Provincial Park; hiking, cultural significance (Tahltan).
Hoodoo MountainYukon, Kluane Volcanic BeltSubglacial / tuya / cinder coneActive; last eruption ~1,000 yr BP (subglacial). Flat-topped, ice-marginal.Kluane National Park UNESCO site; glaciovolcanic features.
Level MountainBC, Northern CordilleranMassive shieldDormant; last ~2.5 Ma. Largest volume Canadian volcano.Nahlin Plateau; caribou range.
Tseax ConeBC, Nass ValleyCinder coneHistoric; erupted ~1700 CE (Nisga'a oral history). Lava flow 22.5 km, killed ~2,000. Canada's deadliest eruption.Nisga'a Memorial Lava Bed Park; culturally sacred.

Monitoring & Risk

  • NRCan / Geological Survey of Canada operates Canadian National Seismograph Network; limited dedicated volcano seismic/gas monitoring (Meager, Cayley, Garibaldi only).
  • No volcano alert level system (unlike USGS). Aviation alerts via Montreal VAAC.
  • Primary hazards: tephra fall (aviation), lahars (glacial melt), landslides (Meager), lava flows (remote).

Why It Matters

While eruptions are rare (centuries to millennia), the 2010 Meager landslide and 2021 Lytton wildfire (pyrocumulonimbus) highlight cascade hazards. Growing population in Sea-to-Sky corridor and geothermal exploration increase exposure. Indigenous knowledge (Nisga'a, Tahltan) preserves eruption histories absent from instrumental record.
