I'm not sure if it would be. David has found a serious flaw in this plan and there's no fix for it, I don't think.
Some people genuinely need to move in to the home they purchased. Scenarios like selling your home in Halifax and being en-route to Victoria behind a moving truck are very real, and happen every day, multiple times a day. Consider individuals who have been posted here by the military. The order is given, they sell their home wherever they are, buy a home in Victoria, and are planning to take occupancy upon their arrival.
A seller must vacate the property that they no longer own. They are neither a renter or an owner and would be occupying the premises illegally.
Right now there is no reason anyone would have to move. We are not formally locked down as a nation but there is no reason people have to move at the moment.
