VANCOUVER - Environment Canada has issued dozens of warnings about heat and poor air quality for much of B.C. as sweltering temperatures aggravate the wildfire situation in the province.

The agency says Lytton in the Fraser Canyon reported the province’s highest temperature of 40.5 degrees, although it wasn’t a daily record, unlike in Cache Creek where it reached 39.1 Celsius, breaking the 37.8 mark set two years ago.
