Immediately before the American Revolution, the area that would become Upper Canada (modern-day Ontario) was largely French-speaking, having been a French colony until 1763 when the British took over. After the American Revolution, however, a large number of English-speaking loyalists migrated from the Thirteen Colonies to the area. This caused such a shift in the demographics and culture that in 1791, the British split the old Province of Quebec creating Upper Canada in order to accomodate the loyalists.
In the area that would become Upper Canada, what was the ratio of French to English speakers before the American Revolution (~1764-1774) and after the American Revolution (~1784-1790)?
I'm trying to determine how big the loyalists' impact on the language demographics really was, because to a decent extent, the relationship between English and French speakers in Canada is still an important and sometimes controversial topic.
