How come there are so many British people in Toronto???

I know exactly what you mean,im British but my Aunt and Uncle live in Toronto.I think its one of those word of mouth things,like we have a lot of expats in Spain.When i was out there,no one took a blind bit of notice about my english accent until i wrote my address down in guestbooks etc and then they were like 'oh your from England'. My uncle works in an office with mainly English people so even though he's been there nearly 30 years,he still sounds English. I also think its like the Australia scenario where a lot of people can trace their great relatives to a part of Britian.I met a lot of Canadians who said their nan came from London etc.There is still strong roots to Britian for a lot of people.Bit round the houses,but i hope this helps anyway.
