As tuscan mentioned, pretty much every condo constructed in Toronto includes a 2-pipe system with fan-coil units. These simply blow the air across a radiator that is either hot or cold. Upgrading to a 4-pipe system adds additional cost, but would benefit people around this time of year when south and west facing units want the AC, but north facing units still need heating.
Architects sometime exacerbate this problem with poor planning. I lived at the Camden Lofts for a long time, and could never understand why the south facing units were 40' wide x 20' deep, while the north facing ones the other way around. We were comfortable, while neighbours across the hall lived in a sauna!
As for heat pumps, they operate a bit differently in that they rely on a 2-pipe system with a stable temperature and then use a compressor to either draw the heat out or into your unit. During days like we've had recently, the heat injected into the system from south facing units, gets transferred to the north-facing units, requiring very little energy to operate. These are great, but I can't think of an example where they have been used in a condo in Toronto.
