That CTV article seems quite vague. At least for the Raptors, "opening the training facilities" means only one player at a time in the building, and one coach or trainer, no close interaction between them, and with disinfection of balls / equipment / surfaces in-between players. Locker rooms, fitness rooms, showers and offices all closed. In that situation, many players would probably just as well want to work out at home, with a trainer watching them over video.

If TFC is training outside, it's lower risk, but it's still likely going to be strongly controlled, with no interaction between players.
Which I think is good. I agree with Red CB, way more testing capacity is needed for this to go further. In Germany they still have some problems and huge debates about the Bundesliga reopening. That's despite the fact that Germany has the capacity to do 850,000 tests per week, yet normally uses less than half that capacity. There it's easy to say that the Bundesliga can pay for extra testing for the players & staff w/o affecting anyone else. In the US and Canada, that's much harder to say.
