The smoke generated by the fires was blown into the Prairie Provinces and created a moderate health risk there leading Environment Canada to declare an air quality advisory for southern Saskatchewan and Manitoba on 9 July.

[2] The smoke reached as far away as Bismarck, North Dakota, over 2,000 km (1,200 mi) south.

[3] The smoke was also observed drifting north into Nunavut[4] and east to the Maritime Provinces and as far as Portugal.

By 9 July an area of 5,000 km2 (1,900 sq mi) had been consumed, about the size of the island of Trinidad.

[1] One study suggested that a record number of lightning ignitions during 2014 drove a significant amount of the fires.
