Makes no sense to look at things in isolation. Liberal support has collapsed amongst pretty much all 'immigrant' communities over the past couple of elections, especially further out into the suburbs. Which is extremely significant as such communities have been one of their main electoral bulwarks since the 1950s and after Trudeau became their main source of strength. The process has been more extreme with Jewish voters though; of course the Tories have been wooing them in a serious way for longer than other minorities and, also, they're a more affluent group overall. Suspect that Israel is a factor for some (especially the more mainstream Orthodox) but generally issues like that are overrated.
The Jewish vote change in recent years has been striking, a lot more than any other immigrant group.
Integration matters here, I suppose. Basically not ethnic whites/ "an immigrant group" anymore. When they
very much used to be.
