Toronto Mayor John Tory has offered the city's support to the residents of Fort McMurray who have been forced to evacuate because of a raging wildfire.

Tory tweeted Wednesday morning that he has reached out to the mayors of Fort McMurray and Edmonton to offer Toronto's assistance.

More than 50,000 residents were ordered to flee Fort McMurray Tuesday night as the wildfire crossed the area’s main highway and threatened multiple neighbourhoods and reached the city’s downtown area. Around 20,000 people are expected to seek shelter in Edmonton.

Hundreds of homes have been destroyed in the urban service town, which is located in the regional municipality of Wood Buffalo in Alberta. 

Ontario’s Ministry of Natural Resources says it will send 100 firefighters who are well trained in battling forest fires as well as 19 supervisory staff to Alberta. They are expected to be stationed in the affected area's forested region as opposed to Fort McMurray itself.

The crew is set to travel to Alberta on Friday and will be departing from Sudbury. They are departing later this week in order to provide relief to front-line crews.

Ontario is in a good position to send resources as our forest-fire threat level sits at a "stable" reading. The low threat of a forest fire in Ontario is mostly due to the longer winter and wet weather conditions, the ministry said.

The province says it has also offered specialized equipment such as seaplane water-bombers and helicopters to Alberta, but no equipment has been requested yet.

Meanwhile, back in the GTA, city council in Mississauga is expected to discuss today whether they will offer an assistance package to Fort McMurray.
