Or is the onus being put on the airline, therefore it's denied boarding rather than denied entry?
I think these are two different things and you need to carefully at the wording. The government of Canada will likely never deny entry to its own citizens'. It is protected in the charter. If someone demonstrates they are a Citizen to a customs/immigration officer they will likely be let in. Perhaps having to quarantine after entry.
They are restricting who can fly on an aircraft. It will be up to the airline to deny boarding.
I believe the pre-clearance treaty between Canada and the US permits Canada to establish pre-clearance at US airports. However Canada has never done pre-clearance anywhere. So it is virtually always the airline that checks that a traveler comes in contact with first.
