More than 300 firefighters from across Canada including New Brunswick are now in British Columbia to relieve those already on the ground battling over 180 wildfires.
Some progress has been made thanks to recent cooler weather but 14,000 residents have been evacuated and thousands more are on alert to leave their homes at short notice.
Forecasters say gusty winds expected this weekend could fan the flames even further and the heat is also expected to return.
The economy of the B.C. Interior is taking a hit this summer with many campgrounds and provincial parks forced to close due to the wildfires and related road closures.

More than 7,000 residents in the Interior and Cariboo regions have been evacuated from communities like Cache Creek, Princeton, Ashcroft and 100 Mile House to be housed in Kamloops.
Temperatures remain hot in these areas this weekend soaring above 30 C.
