I see both sides on this, we really shouldn't be accepting international students (on international student visas) who need food support in the first place.
Yes that means some people will not be able to come here. There's still more applicants than available slots, so no real problem there.
The whole point of exporting education is to make money for Canada though, just like any other export, which doesn't work if they aren't able to pay.
Now if someone is here on a refugee or PR visa, I don't have a problem helping them with food and cost of living.
Also, threatening someone is never the right way to go about discussing policy.
