United States Annexation of Canada

In 2072, the United States of America formally annexed Canada as the Sino-American War heated up at a dramatic rate.

Background
The foundation for Canada's annexation was laid in 2059, with the establishment of the Anchorage Front Line as America's bulwark against the Chinese. National relations between Canada and the United States deteriorated rapidly with continual pressure from the U.S to Canada for authorization to be given for the US Army to protect (and by unofficial extension, claim) the Alaskan oil pipeline hosted on Canadian land.

Permission was eventually granted in 2067, after the Chinese invaded the year before. With its military presence established, the United States began drawing on Canadian resources to support the war effort. By 2069, this process resulted in straining Canadian resources to the breaking point and the destruction of vast stretches of timberland. Canadian protests went unheard. In fact, Canada became known as 'Little America' in the minds of U.S. citizens.

The behavior of the United States in Canada led to mass protests and rioting in several Canadian cities. A 2072 sabotage attempt of the Alaskan pipeline became an excuse for officially beginning the annexation itself, formalizing what was started in 2067 with the garrisoning of U.S. troops on Canadian soil.

This process would be completed nine years after, in 2076. Canada was placed under a draconian military occupation which effectively absorbed the Canadian half of the continent into the United States' borders with all civil rights suspended to the Canadian citizenry. Canadian protesters, rioters, and resistance members were shot on sight, while military units swarmed across the entire length of the Alaskan pipeline. Pictures of atrocities committed by American soldiers made their way into the United States, fueling unrest and protests. At least one soldier of the US Army serving within Canada during the gritty annexation was said to be sickened by the "criminality" of the event.
