The expectation is just to stay 14 days at home. Nothing else.
I arrived from the US a couple of weeks ago and got no follow up at all (no email, no phone call, and no one came knocking).
I have several friends who have travelled over the last couple of months and most of them also had no contact. A couple did receive an email or two, and one guy had a phone call.
Because there are so many people traveling now I think the most you will get is an email.
FYI the police are absolutely NOT sent out unless the Canadian immigration agent specifically suspects you will not comply with the quarantine. There was an article in CBC about this.
If you are landing in YYZ as your final destination you can also opt for a Covid test on arrival, although regardless of the results you still have to complete the quarantine.
