The general trend will be toward more telecommuting, and Covidian times are simply accelerating that along. We'll still see new office towers going up but perhaps not at the frequency we once saw. In my part of the local film and television industry we're being told to generally expect to work primarily from home, albeit with once or twice-weekly visits to the office to talk to department heads and coordinate with other departments. Some good and bad in there but I won't miss commuting daily, especially when a given production is on the other side of the GTA for me. Still, I'm not sure the new provisions will hold once we are post-Covid. The pressure to have real face-time for making quick decisions will likely be immense.
Anyway, it will be interesting to see if the pace of new residential tower builds also slackens off. Will more people opt to leave the city for smaller cities and 'burbs? For many of us the city continues to be a draw, but I wonder if we will see new settlement patterns aided and abetted by greater reliance on tech. Will we see more decentralization?
