Berliner,
It is sad that you have such a bad view of Montreal. I completely disagree on almost every point (the MK had issues years, and years ago but has been a very fine hechsher for a while now).
I don’t know what you mean by “no rosh yeshivas have ever come out of the place.” Many, many very fine bochurim have come out of the Yeshiva and many of them have gone on to be tremendous talmidei chachamim. The Bais Medrash program of the Yeshiva is having problems now but the high school is doing just fine.
The anti-semitism is grossly over-stated. I grew up there and I never felt any “palpable” hatred. The community is actually growing quite nicely (which has led to a housing shortage).
I don’t know your connection to Montreal but it seems like it is really coming through a darkly tinted glass.
