Some data on the Canadian Jewish population is out from the 2021 census, and I'm looking at the census tract level.
In Toronto, Jewish population has really grown in the area I grew up in (St. Clair West area). It's a middle to upper middle class streetcar suburb type area, just south of the Cedarvale ravine (where the Jewish corridor on Bathurst begins). Anecdotally I heard the area was re-emerging as a Jewish hub. Very accessible to Jewish commercial strip on Eglinton and major synagogues, but also to the Annex and other core neighborhoods to the south. Relatively affordable housing compared to Cedarvale and Forest Hill. Jewish population is about 4,000 out of 30,000, up about 70% in just 10 years. A Reform day school campus opened in the area. A lot of Jewish restaurants and businesses have opened:

The area was fairly Jewish during the 1940s, 1950s and 1960s, a sort of transition area between the old inner city Jewish community in the Kensington-Harbord area to the south, and newer suburban areas of Forest Hill, Cedarvale and North York. But by the late 1960s the major synagogue in the area moved to North York, following their congregants, and the community declined. There were some Jews in the area when I was growing up, but it was probably no more than 10% Jewish at most.
Meanwhile, Jews seem to really be moving out of the wealthy Bayview-York Mills area, the northeast edge of the favored quarter. For a generation of doctors and successful businessmen, this was a step up from postwar Jewish middle class Lawrence Manor and Bathurst Manor, and it became as secondary Jewish concentration after Bathurst (but with virutally no Orthodox). Probably about 1/3 Jewish at its peak, now it seems to be no more than 15%. The area is probably about as Chinese as it was Jewish 30 years ago.
