In 1937, two little towns in Saskatchewan (Yellow Grass and Midale) set a temperature record that stood for nearly 84 years, when they hit 45 C.
Yesterday (June 27), Lytton set a new all-time Canadian high, with the mercury hitting 46.1 C.
That record stood for 24 hours, give or take an hour.
Lytton then smashed their own record today, with 47.5 C.
That's 1.4 C higher than the previous day.
And they might add a bit more before the day is done.
"Lytton has again broken the all-time Canadian high temperature record by reaching 47.5 C at 4 p.m.," says Environment Canada in a tweet. "This is a preliminary number as heating may continue for another hour."
For comparison, Death Valley, California is famous for being arguably the hottest place on Earth. Today, they recorded temperatures peaking at 49 C.
It's just one of dozens, if not hundreds, of records being broken over the last few days by the heat wave hitting the West Coast.
Luckily, temperatures are expected to start falling tomorrow.
