Temporary foreign workers are supposed to fill skill gaps in the economy when not enough qualified workers exist, not to supply cheap labour when employers want to improve their bottom line.
Even then it seems like the "temporary" part gets ignored. There should be some requirement to invest in local training for any specialized position that's needed long term/multiple times.
The law just changed to 4 months notice for landlord/family use (3 months if it's for a new buyer) and the landlord/new buyer/family must live there for 12 months (actually live there, not just keep it off the rental market).
