What will be interesting is whether the longer term pattern is to spread attendance out over the work week (say, a 60% of past peak every day, Monday to Friday) or align around a common "at home" day. (Replace Casual Fridays with Work at Home Tuesdays and Fridays). That has a major impact on transit as under the former scenario, ridership will not display the same peaks, whereas under the latter there may still be peaks some days but not others.
I'm a bit suspicious of ideas like this; first because of the real-world experience in the U.S., in tech companies, thus far.
But secondly, because it really doesn't account for childcare, for a start.....
See what happens if you try, with most childcare centres to reserve space only 3 days a week........
I think you'll find you pay for 5, or your child does not have a space.
There are lots of realities like that that creep in...........
Imagine that everyone is told 3 days in the office, 2 at home.
But first, to achieve real estate optimization, those days at home need to be different.
But if they are different........then all your staff can't collaborate in-office; and you couldn't fit them all either.
If everyone's days at home are different, coordination is more of a pain.

None of us know for sure.
But I really don't see remote work taking off, in the near-term, the way some think. (statistically significant change).
I think we continue to see evolution in that direction........but a shift of 1-3% is utterly immaterial to the office market, and the commuting market in Toronto.
