Beating Trump to the punch, Canada has already started construction on their wall .... with a little help from Mother Nature and a very early winter.
It has been given the name Ga- Woc-Wwam - The Great White Canadian Winter Wall of Misery ....
Please note: We must apologize, this is a very unusual form of Cold and heartless Canadian "low humidex" humour. Not intended to offend anyone.
Also note: The term humidex is a Canadian innovation, that was first coined in 1965. The humidex is a dimensionless quantity based on the dew point.
