Record heat believed to have contributed to more than 233 sudden deaths in British Columbia since Friday, officials say.
Authorities say more than 200 people have died in Canada’s westernmost province since Friday, as record-breaking temperatures raise serious concerns for vulnerable groups, including the elderly.
British Columbia’s chief coroner Lisa Lapointe said on Tuesday that the British Columbia (BC) Coroners Service received at least 233 reports of deaths between Friday and Monday afternoon – a total she said was expected to increase as more information becomes available.
Lapointe said the coroners’ service typically receives 130 reports of death over a four-day period.
“Since the onset of the heat wave late last week, the BC Coroners Service has experienced a significant increase in deaths reported where it is suspected that extreme heat has been contributory,” said Lapointe, adding that the exact cause of the deaths was being investigated.
Temperatures have soared in BC and other Canadian provinces and territories as a so-called “heat dome” – a weather system that traps in hot air – descended on the country’s west coast, as well as in the Pacific Northwest of the United States.
“It’s like a lid or a top, and nothing can get in, weather can’t get in to remove that heat, it just builds,” Dave Phillips, a meteorologist with Environment Canada, told CTV’s Your Morning news programme.
Experts have also said climate change contributed to the record-shattering heat. Lytton, a town in central BC, broke Canadian high-temperature records three times this week, hitting 49.6°C (121.28°F) on Tuesday.
Metro Vancouver Police also said on Tuesday evening that officers had responded to more than 65 sudden deaths since the heat wave began on Friday, while police in Burnaby and Surrey, cities in the greater Vancouver area, also reported dozens of sudden deaths.
“Vancouver has never experienced heat like this, and sadly dozens of people are dying because of it,” Sergeant Steve Addison said in a statement.
“The vast majority of these cases are related to the heat,” Addison said. “We’ve never seen anything like this, and it breaks our hearts. If you have an elderly or vulnerable family member, please give them a call or stop by to check on them.”
A heat warning remains in effect for the Greater Vancouver Area, but Environment Canada says on its website that the heat “will become less intense” starting on Wednesday, though temperatures are likely to stay unseasonably warm for the rest of the week.
Environment Canada urged people to stay hydrated and remain indoors, and to check on older family members and neighbours.
The extreme heat is expected to extend to other parts of the country on Thursday, said meteorologist Doug Gillham, with high-temperature records potentially breaking in several cities including Kelowna, BC; Calgary and Edmonton, Alberta; and Saskatoon, Saskatchewan.
“The hot weather will extend all the way to the Northwest Territories and Nunavut,” Gillham said in a post on The Weather Network website.
