With the elimination of France's colonies and hence the danger from French aggression, the English colonies felt a new freedom from dependence on their mother country. The English Parliament was faced with how to evolve it's relationship with the colonies in the areas of representation, taxation, trade, military support and many other issues.
The taxation issue became a bone of contention between |England and many of the colonists with a resultant rift developing between them. As the situation reached a critical point of confrontation, violence broke out and the continental congress representing the 13 colonies decided to invite and invade the former French colonies who had not responded to their entreaties to join them in opposition to England. This invasion and the retrenchment of British troops and naval force to Halifax, drew the line in the sand and the American revolution ground on to a conclusion which saw the informal setting of the future US/Canadian boarders and territories.
