Police say a sweltering heat wave that has settled over Western Canada for several days is believed to be a contributing factor in dozens of sudden-death calls they have responded to in Metro Vancouver.
Cpl. Mike Kalanj of Burnaby RCMP said Tuesday the 25 sudden-death calls the detachment responded to relate to a single 24-hour period starting on Monday.
The deaths are still under investigation and many of the deceased were seniors, he said.
Temperatures in the Vancouver area reached just under 32 C Monday, but the humidity made it feel close to 40 C in areas that aren't near water, Environment Canada said.
The record-breaking heat wave could ease over parts of British Columbia, Yukon and the Northwest Territories by Wednesday, but any reprieve for the Prairie provinces is further off.
In a news release, Kalanj urged residents to check on their neighbours and family members.
“We are seeing this weather can be deadly for vulnerable members of our community, especially the elderly and those with underlying health issues," he said in the statement.

In Vancouver, the police department said it had redeployed dozens of officers and asked the public to only call 911 during emergencies because heat-related deaths had depleted front-line resources and delayed response times.
"Vancouver has never experienced heat like this, and sadly dozens of people are dying because of it," Sgt. Steve Addison said in a news release. "Our officers are stretched thin, but we're still doing everything we can to keep people safe."
As of mid-afternoon on Tuesday, he said police had responded to more than 65 sudden deaths since the heat wave began on Friday.
"The vast majority of these cases are related to the heat," Addison said, adding that on a typical day, Vancouver police respond to between three and four sudden-death calls.
British Columbia's chief coroner, Lisa Lapointe, said her office would normally receive about 130 reports of death over a four-day period. At least 233 deaths were reported from Friday to 3 p.m. on Monday, she said.
"Coroners are carefully gathering all information available for each death reported, to determine the cause and manner of death, and whether excessive heat played a role," she said in a statement.
"Environmental heat exposure can lead to severe or fatal results, particularly in older people, infants and young children and those with chronic illnesses."
Ingrid Jarrett, CEO of the B.C. Hotel Association, said residents in parts of the Lower Mainland, Victoria and the Okanagan region have been booking air-conditioned rooms so they can continue working and also get some sleep.
A lack of staff is the biggest challenge for hotels, motels and resorts, she said.
"So many hotels have to limit their occupancy and reservations that they can take because they simply don't have enough people working in order to clean the rooms," said Jarrett, who did not yet have the latest occupancy numbers for this week.
Environment Canada said the "historic" weather system shattered 103 heat records across B.C., Alberta, Yukon and N.W.T. on Monday.
Those records include a new Canadian high temperature of 47.9 C set in Lytton, B.C., smashing the previous record of 46.6 set in the same village a day earlier.
Temperature records were also set in the Alberta communities of Jasper, Grande Prairie and Hendrickson Creek for a second day as the mercury hit the mid- to high 30s.
It was 38.1 C in the Nahanni Butte region of N.W.T.
The weather office has also issued four heat warnings for regions along Manitoba's western boundary.
Forecasters warn extreme conditions will persist across the Prairies at least through this week and possibly into next.
As the sweltering system slides out of B.C., temperatures are expected to dip to more seasonal levels. The weather office is calling for a chance of lightning Wednesday night in the parched southern Interior. It's the same area where evacuation alerts were issued Monday because of a wildfire.
The BC Wildfire Service announced a provincewide campfire ban effective at noon Wednesday, as the fire risk across most of B.C. is rated at high to extreme. The ban, which also covers fireworks, torches and burn barrels, remains in effect until Oct. 15.
