Do you have any idea how high the cost of living in Toronto is?
People keep trumpeting this over and over but it isn't comparable. You make so much more money in Toronto, pay a ton less in taxes, sales tax is lower, and prices for many, many things are lower compared to here.
Cost of living in Montreal is cheap if you want to live in an old cheap apartment in Verdun and take the metro everywhere.
It isn't very cheap to live here if you're wealthy and you want to live a wealthy lifestyle.
At my old company (major Canadian bank), you instantly get a $10-15k pay increase for the same position in Toronto, and that's not factoring in the increase in your take home pay due to lower taxes.
Plus **** is really bad here lately. I have a lot of friends who are having serious trouble finding work. In professional industries. Several owned businesses that have closed and they are struggling now to find something else. Many are looking at Toronto, actually.
