A wildfire of epic proportions has now driven almost all 80,000 residents from the oilfields' capital of Fort McMurray, Alberta, as much of the community has gone up in flames.
Spawned by high winds, scorching heat and low humidity, the fire changed course and took aim at the city, causing residents to flee in a mass exodus that included huge convoys by road and some evacuations by air.
Police and the military were escorting a procession of 1,500 vehicles carrying evacuees stranded at oilfield camps north of the city to safer ground.
Heavy smoke was hampering their travel that was continuing this weekend to the Edmonton area, about 270 miles to the south.
"The beast is still up, it's surrounding the city and we're here doing our very best for you," regional fire chief Darby Allen said in assessing the situation.
Thousands of houses and buildings have been destroyed and Premier Rachel Notley said she cannot speculate on when it might be safe for residents to return to the city.
The Red Cross has raised $11 million and Prime Minister Justin Trudeau said his government will match the donations to help those displaced.
The Alberta government is also matching donations up to $2 million.
"We will weather this storm together and together we will rebuild," Trudeau said.
Mail delivery decision is under review
Canada's Liberal government has launched a formal review of the previous Conservative decision to phase out door-to-door mail delivery.
Prime Minister Trudeau pledged to restore home delivery during last fall's election campaign and then halted the ongoing transition to community mailboxes.
A four-member independent panel is reviewing the decision made as a cost-cutting move by Canada Post, a government corporation.
The panel is to provide an interim report by the end of the summer and final recommendations by the end of the year about mail delivery and other potential money-making ventures for the post office.
