Any average is going to be a meaningless because Canada covers over 9 million sq/kms, extending from the North Pole to below the 49th parallel and both east and west coasts of North America. That includes some of the worlds driest deserts and rainforests. But for the heck of it some figure it to be 5c (year average) and 50 cm.

90° north latitude (the north pole) and 90° south latitude (the south pole)
No. The North Pole has lower average temperatures then Mt. Everest.

The annual mean temperature at the South Pole in winter is -76 °F (-60 °C) and -18 °F (-28.2 °C) in summer. The annual mean temperature at the North Pole is -40 °F (-40 °C) in winter and 32 °F (0 °C) in summer. Note that the average elevation of Antarctica is considerably higher than the Arctic, so the temperatures are expected to be much lower.
On the average, cold, with little precipitation.
The South Pole has more land around the pole. The continent of Antarctica has an average revelation above sea level of +6000 ft The North Pole is covered by floating sea ice.
the hardest environment would probably be the north and south pole because it is really cold and very little rainfall
Its probably very cold.
