We lived in europe for a few years, then in Singapore for three years and are currently in Toronto since about a year.
We agree with most posters about money, travelling, weather, etc.
In terms of everyday life, except for booze, groceries, cigarettes, clothes, restaurants, movies, cabs, parking, gas (petrol), etc is significantly more expensive than Singapore.
Healthcare in Toronto is awful. Although touted as "free" but in reality, it is not. You will have to shell out nearly C$2000 to pay for OHIP ("free medical service"), and to buy a prescription drug/dental/vision cover. And then ofciurse, you have no control over which doctor you will see and when.
Banks are very conservative and demand money for giving you the privilege of having an account with them.
Public transport is nowhere as efficient as Singapore. CableTV, Internet, and fixed line phones are atleast 5 years behind - though some choices on cable (adult) are better than Singapore.
Only 1 real GSM phone company (Rogers, which owns Fido as well). People do not even know what 3G is. No SAM machines, no EMAS, no pro-active governance. No subway link to airport.
Cheap flights are much more expensive in comparision to AirAsia, Tiger, etc.
Great weather (winter is not that bad), access to beautiful nature-areas (for a fee), courteous and polite people, pro-active media, frrdom of speech.
