The numbers behind Canada’s worst wildfires season

This has been - by some distance - the worst wildfire season in Canada's history.

This week, thousands of people in the western and northern parts of the country have been forced to flee their homes.

Others have been told to be ready to leave at a moment's notice.

There are over 1,000 active wildfires nationwide and two-thirds of those are classed as out of control, according to the Canadian Interagency Forest Fire Center.
