Yeah, so there's a few factors behind those numbers:
those kids are most likely concentrated in pockets in the old outer boroughs of Metro Toronto: Etobicoke, Scarborough and North York. Most of the core of the city - the upside-down T - running roughly from the 401 down the middle of the city to the lake and east and west in old "streetcar suburbs" are still, in many areas, predominately White
a lot of Muslims pack families into shitty apartments in certain corridors (Dixon Road, Don Mills and Flemington Park, Jane and Finch, Malvern etc.) and once they can, they move out to Mississauga and Brampton and Milton; just like jeets they hate "old" houses in the core, and move to new slopshit subdivisions that quickly become shitty slums; so the seemingly high numbers you see in the city proper are probably, to some extent, transitory
the "moderate" Muslims with money - Persians especially - focus on a couple of areas: Yorkville and the Yonge corridor from Sheppard up to Steeles; from experience they're the best to deal with and relatively civilized
I don't see those patterns changing much long term other than Mississauga, Brampton, Ajax and Oshawa increasing their Muslim share. They outbreed everyone else and won't settle for shitty shoebox condos at Bay and College for long.
Whenever I read the scriptures of the world's various religions I always think "where were the editors when this was written? Where were the damage control teams to go back and clean up all this embarrassing shit?" Even modern movie productions employ continuity people and script doctors to make sure the story doesn't go off the rails, but religions just say "if any of this doesn't make sense to you, it's because you're evil" and leave it at that
I've said it before, but if there's ever going to be a full-blown race war in this country it'll be between the various religious flavours of subcontinentals and Middle Easterners and whites aren't going to be involved in it at all (at least at first)
So those are 2021 numbers. Probably higher now. Be interesting to see the census results. Old Stock classic Canadians I would say are less than 60% overall under 50% in places like Vancouver, Sar Ree, Browntown, Toronto etc
From the data I've looked at the idea that after a certain percentage of Muslims, the trajectory is irreversible such that your country becomes majority Muslims is incorrect.
Canada can still exterminate all non-Whites from the country with the right government, in theory.
The biggest issue with a large Muslim population is we also have a large Indian population. 10% Muslims and 10% Indians is just asking for trouble. Indians hate Muslims more than blacks hate Whites.
