the yeshivas in montreal are really very good. in the “devimy” area, there are 2 yeshivas. one is more, what we can describe as, communal (a mix of yeshivish, lubavitch, sefardim, etc.) the other yeshiva is more hungarian-semi-chassidish/heimish, with all limudei kodesh in yiddish.
no major problems in the youth sector, though no city is perfect in this area. but in general perspective a very fine yeshiva system, and most boys are really really good.
agav, this week, montreal will host its annual siyum hamishnayos which will bring in boys from ottawa, ny, lakewood, and other cities, and is a major highlight of the boys’ year.
the bais yakkov school is top notch education wise and the girls who have gone through that school are generally frum, well-behaved, tzniusdik girls.
