Wrong, Mark. First of all, my father is an ex-Montrealer, not me. I'm an ex-Canadian, but that's besides the point. And if it makes you feel any better, I think Toronto is a shithole (I lived there for a bit), but that's another debate.
Here are the largest Jewish cities in the North America:
New York 1,900,000
Los Angeles, California 585,000
Miami, Florida 535,000
Philadelphia, Pennsylvania 315,000
Chicago, Illinois 250,000
Boston, Massachusetts 228,000
San Francisco, California 210,000
Toronto, Ontario 175,000
Washington, DC 165,000
Baltimore, Maryland 100,000
Montreal, Quebec 100,000
I think L.A. and New York's population is a bit more than the figures above because Orange County (L.A.) and Rockland County (NYC) are not included in these figures.

If it also makes you feel better, Jews are moving out of Toronto as well. Mostly to Vancouver, the U.S. or Israel. They're not very happy about the way the Canadian government has handled the Israeli-Palestinian issue. Canadian Jews are very, very sensitive about this...a lot more than their counterparts down here.
