Grieving parents who lost their nine-year-old boy last week say their son died after a severe asthma attack made worse by wildfire smoke engulfing parts of British Columbia.

The wildfire has now grown to 565 square kilometres in size.

Air quality alerts remain in place for several areas in B.C.'s southern Interior on Tuesday as more than 200 wildfires continue to burn through hundreds of square kilometres of the province.

"Environment Canada is currently predicting highs of 21–22 C Friday to Sunday this week (Thursday is just short at 19 C). That's well above the normal for this time of year, says Environment Canada meteorologist Lisa Erven, which usually sits at 17 C, but won't be record setting."
