The fall of Quebec City is in 1760. Americans were still Perfide Albion as far as they could see. Also what was the reaction to the Quebec act you mentioned? Never heard about the American opinion of that.

Bailyn’s Ideological Origins of the American Revolution is quite old at this point, but he does a very good job explaining how the Quebec Act was seen by American colonists as a threat to *Protestant* religious freedom – that by empowering the Catholic Church in Quebec, it was creating a precedent to create established religion and/or “papism” in the American colonies.
