You probably guessed they'll be below or at zero for the next week says Environment Canada.
Under partly cloudy skies, temperatures will drop to minus 1 overnight tonight (Friday) before struggling to reach just 6 Saturday.
We may see our first snowflurries of the season Sunday night as the low hits minus 2.
Monday will be cloudy with 30 percent chance of showers and a high of only plus 5.
The lows for Monday, Tuesday and Wednesday will be in the minus 4 range.
The normals for this time of year see highs of plus 9 and lows of plus one, so it's definitely going to be sweater time.
The highest temp ever on this day is 22.2°C in 1971, and the lowest was -7.2°C in 1959.
