Canadian Civil War

The Canadian Civil War was a short was that lasted from May to September.

Causes
The Canadian province of Quebec had long been different from Canada (they speak french) but in early 2048 it all came to a head. The Quebec council held a meeting in March, and in April they declared that they would be seceding from Canada. Canada objected.

Given that nearly all Quebecians supported the breakaway, and the fact that the Canadian government didn't want to kill citizens, Canada pleaded to the United States. Then, on May 29, the US and Canadian forces stormed Quebec.
