Environment Canada issued heat warnings for most of Alberta along with parts of Saskatchewan and Manitoba this week in the wake of sizzling high temperatures.
The weather office says a daytime maximum of 30 C or higher could pose an elevated risk of heat-related illnesses and residents should avoid outdoor activities until cooler hours of the day.
