I don't want to get too sidetracked into Jewish voting patterns around the world, but i should point out that the "pro-Israel" swing to the right in Jewish parts of Montreal, Toronto, or Orthodox parts of Brooklyn etc...do not exactly fit the "affluence" pattern. The Orthodox Jews who support Trump are generally very low income...and ditto for the ultra orthodox enclaves in Canada that might hypothetically support extreme right candidates. The ultra orthodox tend to have large families and often times no one makes any money since the men just study the Torah all day and live off handouts. Poverty is a big problem. The enclaves where there are a lot of very affluent Jews (i.e. Beverly Hills, the upper east side etc...) won't touch Trump with a ten foot poll. In the 2014 Toronto mayoral election, the affluent Jewish areas of Toronto pretty overwhelmingly preferred John "noblesse oblige" Tory over Doug "rightwing populist" Ford.
Your perception of Beverly Hills is a few decades out of date. It's not mostly made up of liberal Ashkenazi Jews and people in Hollywood etc. anymore. It's about 25% Iranian Jewish and is actually very conservative and "Trumpy" by L.A. standards.
In Montreal, the Hasidim live in Outremont. Hampstead/Cote St. Luc are where the Conservative, Modern Orthodox and traditional Sephardim live. Westmount is where affluent, liberally minded Jews live (you'll find a similar Jewish demographic in Toronto's St. Paul's riding).
