Environment Canada issued heat warnings for most of Alberta along with parts of Saskatchewan and Manitoba this week in the wake of sizzling high temperatures.
The weather office says a daytime maximum of 30 C or higher could pose an elevated risk of heat-related illnesses and residents should avoid outdoor activities until cooler hours of the day.
Temperatures could climb to 33 C as far north as Thompson and almost 30 C in Churchill along the Hudson Bay coast.
Forecasters say the extreme heat will continue this weekend but a slight cool down is expected early next week.
Weather watches, warnings, statements re: heat and thunderstorms, 08 July 2017 (Environment Canada)
A strong ridge of high pressure over Western Canada has pushed the thermometer into record high territory for British Columbia and Alberta.
On 07 July, dozens of communities set new maximum temperatures with the highest at 39.4 C in Warfield and 38.3 C in Nelson but the hot spot in Canada was Garden River in northern Alberta at 40.3 C.
The major cities were warm too with Calgary reaching 33 C and Edmonton 30 C.
Heat warnings have been issued for most of Alberta and parts of Saskatchewan where temperatures will be near 29 C or higher for the next few days and residents are urged to take precautions.
Smoke from forest fires in Western Canada drifts south deep into the USA, 29 June 2015 (NASA)
Hundreds of forest fires are burning in Alberta, Saskatchewan and the Northwest Territories thanks to recent warm, dry weather and smoke is being carried south well into the United States this week thanks to a big dip in the jet stream.
New Brunswick has sent at least 34 firefighters from the Department of Natural Resources to help out in Western Canada since the season to date here has been very quiet.
At least 5,000 people from several northern Saskatchewan communities have been evacuated due to the fires and the Red Cross says they are being housed at several shelters across the province.
The polar vortex has migrated much further south than usual bringing bitterly cold weather to much of Canada and the United States.
Temperatures have not been this cold in at least two decades and many records are expected to be broken over the next few days.
Many cities will experience unbearable cold with wind chills ranging from -50 in Western Canada to as low as -25 in the Southern United States.
The polar vortex typically sits near the North Pole and circulates a pool of cold, dense air in a counter-clockwise direction but an unusually southerly jetstream has carried it southward.
