Ring of Fire of space weather, earthquakes, tsunamis, volcanoes, and landslides. British Columbia and Yukon are home to a vast region of volcanoes and volcanic activity in the Pacific Ring of Fire. Several mountains in populated areas of British Columbia are dormant volcanoes. Most of these were active during the Pleistocene and Holocene epochs. Although none of Canada's volcanoes are currently erupting, several volcanoes, volcanic fields, and volcanic centers are considered potentially active.

Ring of Fire (Northern Ontario) of about "1.5 million hectares". Although the Ring of Fire crescent covers 5,000 square kilometres (approximately 1,930 square miles), most discoveries made by 2012 were within a twenty-kilometre-long strip. Ontario's Minister of Northern Development, Mines and Forestry Michael Gravelle called the region "home to one of the most promising mineral development opportunities in Ontario in more than a century". Tony Clement, Canada's Treasury Board President and the FedNor minister responsible for the Ring of Fire, claimed it will be the economic equivalent of the Athabasca oil sands, with a potential of generating $120 billion. Clement says the Ring of Fire
