There will be some residents that will be shocked to experience the huge increase of maintenance fees after the first year. The average 50cents/sq.ft. that most developers are stating for their new construction condos are generally low to begin with, with or without amenities. The average for all condos in Toronto (new and old) is at 70 cents, of course there are many factors that could make the maintenance higher or lower than this.
Maintaining a pool here is different than Florida, where pools are used year round and they have a much warmer climate. Here they need to be drained and cleaned yearly and heating the pool is a big expense especially with our cooler evenings and off-peak seasons. 12 Degrees also has a roof top deck/lounge/bar amenity connected to this pool which is extremely luxurious and substantial for a building of that size. The insurance for a pool and also potential problems associated with it is not cheap either and will become more of an issue as the building ages.
There are a few purely residential condo buildings that have an outdoor pool amenity in the city (there are a couple in Cityplace and some near Lakeshore), but those serve 500 to almost 1000 units so the maintenance cost is spread over a much larger pool of people.
12 Degrees is a very nicely designed building with excellent amenities and generally speaking I'm sure most will enjoy the perks and will be willing to pay the premium maintenance fees that go along with it.
