The warning says "dangerously hot and humid" conditions are expected for most of the week. Daytime highs on Monday through Thursday are expected to be between 30 and 35 C with humidex values between 40 and 45.
There will be "little relief" in the nighttime hours, as overnight lows are expected to be between 18 and 23 C with humidex values of 26 to 30.
"Watch out for heat related impacts such as heat exhaustion and/or heat stroke. Remember to drink plenty of water," the weather agency says on its website.
The hottest day is expected to be on Tuesday, with highs temperatures expected to reach 34 C in Ottawa. It's also forecasted to be the hottest day of the year so far.
Environment Canada has also issued heat warnings stretching from Windsor to Ottawa, and northward to Moosonee. A special weather statement for heat has been issued for western and southern Quebec.
Senior climatologist David Phillips told Newstalk 580 CFRA that while the expected hot and humid conditions are normal in the summer, the first heat wave is the most significant.
"The fact is just people aren’t ready for it yet," he said. "From a health point of view, the first heatwave is often where we see hospitalizations."

Phillips says the upcoming weather event is significant for its duration.
“It's not a severe weather event that comes and then goes. This has got legs to it. It's a heat dome," he said.
He recommends drinking lots of water and staying away from caffeine or alcohol. Keep an extra eye out for pets and children.
According to Ottawa Public Health (OPH), extreme heat affects children, people with chronic illnesses and the elderly the most. The health authority says extreme heat can cause dehydration, heat exhaustion, heat strokes and sunburns.
