My understanding is that condo fees are set by the condo administrative board (or something like that, I don't know the precise name), of which you as a condo owner are legally entitled to sit in, and they vote on the condo fees based on the reserve pool, need for maintenance and security, etc.
I have had several friends who have purchased both free-standing homes and condos, and whether one is beneficial than the others really depends on where you choose to live, employment, and other factors.
Free-standing homes often (although not always) tend to appreciate in value over time, so for resale purposes, it may be a wiser investment. Also, if you intend to raise a family, homes tend to be more spacious. On the other hand, homes can be very expensive to maintain, and you are responsible for shovelling the snow in the driveway, paying for electricity and hydro bills, and maintaining the security of your home.
Condo ownership tends to be very convenient in that regard, in that maintenance and security are provided by the condo association. Many condos, especially in the GTA tend to be located in areas close to major shopping centres or areas of employment, leading to commuting convenience. Also, for many (but not all) condos, your electricity and hydro bills are included in the monthly condo fees. However, condos tend to depreciate in value over time, and poorly designed condos can have issues with noise from neighbours or plumbing issues as well. Condos tend to be smaller as well, which is not too convenient for families.
Bottom line:
(1) If you are single, and live alone within the GTA, condos are probably the best investment.
(2) If you travel frequently (for work or pleasure), condos are probably also the best investment.
(3) If you live with a group of people or have a family, homes are probably the best investment.
Just my 2 cents worth.
