Quebec's construction holiday is expected to end the way it started -- with stifling heat and humidity.

Environment and Climate Change Canada has issued a heat warning for southwestern Quebec.

People are encouraged to drink plenty of water before getting thirsty, stay in cool places and schedule outdoor activities during cooler times of the day.

Outdoor workers are encouraged to take frequent breaks.
