Enjoy the hot summer weather while you can.

The heat wave gripping the eastern half of the country could be 2010’s last blast of extreme heat as cooler temperatures — think high teens and low 20s — arrive for the Labour Day weekend.

Dozens of temperature records have been smashed in Central Canada and the Maritimes over the past few days as the region swelters under a warm and humid air mass.

In Ontario, so many records were broken that it’s “almost too numerous to mention,” said Environment Canada meteorologist Geoff Coulson.

Toronto hit its expected high of 32 C yesterday.

That’s three consecutive days of 32 C temperatures, which is the definition of a heat wave.

But Coulson said it didn’t break the old mark of 35.6 C set in 1953.
