Small numbers of subsistence and traditional/ritual hunting by the Inuit, not "quite a lot" and monitored by the Department of Fisheries.

I think they allow First Nations to hunt a certain amount —don’t know how that affects sustainability though; it’s for sustenance.

First Nations hunting rights typically do not extend to commercial rights (i.e., first nations can hunt but not sell the meat) so I would be surprised to learn there's much in the way of whaling still happening nowadays. First I heard of it still being legal, though I'm not surprised to learn it - treaty rights are very slow to be renegotiated.

Japan is restarting their whaling, after 30 years

A lot no. Some, in sustainable ways yes.
