Despite the fact that it's only May 28, it was a scorcher in southwestern Ontario, with the temperature peaking at 33.1 C in Waterloo Region.
That high broke the previous record of 32 C set on this date in 1987. The highest temperature ever recorded in the month of May is 33.3 C.
Environment Canada issued a special weather statement regarding the hot and humid air mass as well as a smog advisory for much of the region.
They were also warning that the hot temperatures and increasing humidity could push humidex values into the high thirties.
Nonetheless, most people around Waterloo Region were clearly enjoying the warm weather.
One person told CTV News "It's fantastic, it's going to be a little humid, but it's that time of year so why not. Gotta love it."
Another says "I think it's awesome. I just came from Vancouver so this is great – no rain."
Anyone looking for an open public pool to cool off was out of luck though, since many aren't set to open until June.
In Toronto, a heat alert was issued by the city's medical officer of health.
Officials there were advising people to check up on family, friends and neighbours, especially seniors who are at greater risk.
Environment Canads is also asking people to do their best to reduce air pollution by using transportation alternatives.
People should also drink a lot of water, avoid the sun and go to air conditioned locations like shopping malls and community centres.
