Actually, the crime rate in Toronto is relatively low and the city actually has a reputation of being one of the safer cities in North America. Check this link out:
CTV.ca | Despite rise, police say T.O. murder rate 'low'
Toronto Cost of Living says "According to Runheimer International, Toronto is one of the least expensive cities to live in the world."
But according to
Cost of Living in Canada "The survey revealed that
Toronto has the highest
cost of living in Canada, followed by Vancouver, Calgary, Montreal, and Ottawa." so I'm sure the cost of living in Toronto will be more expensive than your native Calgary, but I doubt it'll be a significant increase.
I quickly googled up this link:
Toronto Apartment Rentals Search apartments for rent in Toronto, Ontario. which obviously shows apartments for rent. The prices they show are pretty low (and I'm sure there is some kind of drawback), but that "Lansdowne Ave. & Queen St. W." location actually falls under the downtown category and is an area that is quickly improving (due to the fact that the renowned Drake Hotel isn't too far off). Anyway, I was just using that one location as an example, that with some time spent searching, you can easily find a good bachelor's place for a low price in a decent location.
Hope that helped, and I hope you enjoy all the art and culture Toronto has to offer :biggrin1:.
