Hello Kuno.

I will try to explain to you the history as I know it.

Canada went into full scale civilian vehilce production after WW2 to fill the needs of the populace for new cars and trucks. Production lines ceased producing civvy cars in around early 1942.

After the war, Canada's military decided to adopt the American styled military vehicles, commonly known as M-series.
I believe the idea was to streamline the vehicle types used by close allies such as the US and Canada, especially under the newly formed NATO pact and United Nations agreements.

I also believe that there was a certain degree of political and economic pressure to buy American made products. I am unsure of all the reasonings behind this, maybe someone could fill in the blanks.
