Thirteen colonies in 1776 came together to revolt against its British rulers in what was to be named in history as the American Revolution. This brought about great change to North America not only now to a new country (The United States) but also to Canada. The Patriots defeated its British rulers and began to look down onto the Loyalists that remained, fearing their own lives and well being they were forced to leave their homes and move a British ruled colony, generally that of the Northern Colonies.
When an uprising was in the works delegates from 13 colonies, all but Quebec, Nova Scotia, Saint John's Island, Newfoundland and Georgia were asked to attend. So why were they not asked to become involved? These colonies were working advancement, unlike its 13 brothers there were well behind in this field. This is believed why they were omitted from the delegation. Also the northern 4 were not falling under the direct hardship as the rest of the colonies had been. After France was beaten and Britain took control they left many of the laws and way of life constant, thus the northern population were not as angry towards their British rulers.
So when the Battle of Saratoga ended with an American victory and the Loyalists were expelled from the United States, there only refuge was that of the northern British colonies. This brought about a dramatic increase in population to British North America. Nova Scotia was bombarded with former Americans, so many in fact it led to the separation of Nova Scotia into two more parts, New Brunswick and Cape Breton. Not only were the Atlantic colonies experiencing a population growth but also Quebec was soon being swamped with English speaking refugees from the south.
The population growth was phenomenal, so much in fact laws and Acts were being questioned, seeing how they were meant and aimed towards the older French fashions, new English inhabitants sought for a change.
