Early Immigrants
It is the early 19th century and in both British and French North America, there is massive amounts of immigration, mostly from northern and western Europe at first, both British and French settlers are arriving to North America in droves, Immigrants would come to North America, both British and French North America, for a boat load of different reasons, but it would mostly be for better job and economic opportunities, fleeing persecution, some would flee from desperate poverty as well, and crop failures, and those aren’t just the only reasons, those are just a few mentioned.
Ireland, due to the potato famine that struck Ireland, and since there would be a British and a French North America and the British being Protestant and the French being Catholic, would make places where immigrants would immigrate to be more determined on religion than they were in our timeline, the Irish Catholics would mostly settle in French North America, due to their shared Catholic faith and their disdain for British authority, meanwhile the Irish Protestants such as the Ulster Scots, would settle in British North America due to their shared Protestant faith, and the Irish Protestants didn’t really have it as bad as the Irish Catholics did under British rule, and their Protestant faith would make them loyal to the British Empire.
The Irish as well as the British and French aren’t the only immigrant groups coming in droves to North America, there are also a large amount of German immigrants as well, Catholic Germans from the southern and western regions of Germany would mostly migrate to French North America while the Protestant Germans mostly coming from the Northern part of Germany would migrate to British North America again this has to do with their shared faith.
Cities like New York, Philadelphia, Boston in British North America while the cities in French North America that will be booming would be Montreal, Quebec City, Taranteau (OTL Toronto), Ottawa (OTL Ottawa, it would likely have the same name), would be the main industrial centers in French North America, due to the industrial revolution creating many new economic and job opportunities, with new industries being created by the industrial revolution, there would be new things such as textiles and heavy industry, this industrial boom would attract a huge amount of immigrants, just like they did in our timeline, from many parts of not only Europe, but also much of the Americans from the rural areas, especially from the South would also relocate to the major cities in the North as well. Chicago would be split with British and the French parts, and Chicago would most definitely be apart of both French and British North America due to its geographic location.
