You must be refering to Arctic Canada. An example would be Yellowknife, Nortwest Territories, which gets about as much precipation as Phoenix, AZ. High relative humidity does not lead to a lot of precipitation in a very cold climate. Cold air holds less water in vapor form.
canada has higher temperature
The potential evapotranspiration is greater in the southwestern United States than in northern Canada.
