Found these trivia on the cold weather....http://www.cbc.ca/news/background/forces of nature/windchil.html

The coldest wind chill recorded in Canada was at Pelly Bay, Nunavut, on January 13, 1975, when 56 km/h winds (a wind chill factor of 3,357 watts/m²) made the temperature of ‑51 C feel more like ‑92 C. Pelly Bay is now called Kugaaruk.

The average high temperature in Yellowknife in January is ‑23.9 C. The average low is ‑32.2.

Temperatures in Ottawa are similar to those in Russia's capital. For the month of January, Ottawa's average high is ‑6.3 C and average low is ‑15.5 C, while Moscow's average high is ‑7 C and average low is ‑13 C. Average highs and lows for July, the warmest month, are also close for the two cities.

The wood frog, which is commonly found across Canada, has what's called freeze tolerance. In winter, the wood frog hibernates on land, usually using only a pile of leaves for shelter. Because this leaves it exposed to the cold, frost penetrates its skin and freezes its internal organs, halts blood flow and stops respiration. The heart stops beating and muscles stop moving. The wood frog's body functions return to normal when it thaws.
