If you are looking at downtown Toronto, I think the prices would be very similar to Vancouver. My parents just purchased a one-bedroom condo there for investment for CA$250,000. They are hoping to resell it for about $350K after collecting some rent income for a few years. It is brand new but won't be built until 2012, so obviously it's a long-term investment. You cannot expect the prices in Canada to skyrocket like Singapore because all they have is space down here. And you also have to remember to factor in the 7% realtor's commission, sales tax, and property tax into it as well.
The GTA (Greater Toronto Area) consists of over 50+ suburbs. There are suburbs that are directly adjacent to downtown Toronto, such as Markham, Richmond Hill, and Missisuagua (6th largest city in Canada, despite being part of the GTA). The prices in these areas are also pretty high, approximately $300k for a 2-bedroom condo to about $400-500k for a townhouse or a semi, and $600-800k for a standalone house. These suburbs are very crowded and very few new landed properties are being built, unless you want to buy resale. Needless to say, these are also very highly-Cantonese populated suburbs because the Chinese like to cluster. There are some condos that are still being built though, but they tend to be very small and not have more than 2 bedrooms, so if you have at least 2 kids you might not want to live in a condo. Most condos also tend to only provide 1 parking lot, so if you are a 2-car family it will be a problem.
The further out of the GTA you go, the cheaper it is. My parents settled in Brampton, which is about 35 minutes from downtown Toronto and their brand-new 4-bedroom, 3000 sq. ft. house cost $350k, about $400k including all the expenses. They paid a bit more because it was a corner house with a big garden. The semi-D across the street cost about $250k.
When my parents first landed in 2005, they purchased a 2-bedroom condo in Mississauga for $280k. Their intention was to settle in it when they made the move in 2007, but it wasn't built until 2008. They take 4-5 years to build up projects here because they can't do much work during the winters. It was in a good location, right next to highway exit, adjacent to train station, and next to a big shopping mall. However they decided that it was too small and are currently renting it out for $1800 a month which basically covers the mortgage and they intend to sell it when the lease expires. They tried looking for houses in the Mississauga and Markham areas too but all they could find were resale houses and none of them seemed to be in good shape.
All in all, the housing is definitely more affordable than Singapore and the price you pay for a condo in Singapore you can buy 2-3 condos here depending on price or location. But do not expect the property prices to double like in Singapore, you'll be lucky to get 20% above what you paid after 5 years. If you do not intend to resell or resettle for a while, buy a place in a new estate. The price will increase when amenities such as schools or strip malls and community centers and parks get built. The price of my parents' property jumped 10% when a middle-school was built right in their estate. The further outside the city you go, the cheaper it will be. When I get a job and get settled I'll probably move out and get a one-bedroom or a studio (the smaller it is, the less I have to clean) in a downtown area (not necessarily Toronto, i'm open to moving anywhere).
Can't sleep 'cos I'm worried about getting a job here. I'll probably flip burgers for a while until something in my field comes along. Big step down but I guess all immigrants must start somewhere.
