People need to keep in mind OTL Montreal has a large enough Jewish community that it is famed for the local variety of bagels and "smoked meat" (ie pastrami). Same with Toronto (my professor was a Jewish man from Toronto) which also received a good amount of Italian immigration.
Some of it is American influence, but Evangelicalism also seems stronger in Canada compared to the UK as seen by former Prime Minister Stephen Harper being one. I think one potential divergence is a larger Anglican church that retains a significant low church evangelical wing and is much more theologically conservative compared to the OTL Episcopalian Church.
