If the system is functioning correctly, provincial and territorial taxes are collected from everyone in the province or territory and the services they fund are disbursed where they are the most helpful, not to the people who paid the most in. Sometimes that means that money flows from a larger population to a smaller one, if the smaller population's needs are greater.

I take it you've never lived in a rural or remote community. They tend to be disproportionately underfunded and impoverished (and in the Territories, many of the people living in those places are from Indigenous or mixed-race backgrounds, whice opens a whole other can of worms).

Not that couriering a few pills up to sit on a shelf along with the painkillers and disinfectants requires a lot of funds—I'd guess less than $100/community/year, and it would have to be a pretty sad place if the inhabitants aren't paying even that in taxes. We are not talking about surgical abortions here. We are talking about a few bloody pills that can be prescribed as necessary via pre-existing telemedecine setups if no one on site is qualified, and disbursed by the nurse running the clinic.

(Edit: I admit that I'm assuming the Territories use a similar model to remote Ontario communities like Kashechewan, where the government will fund nursing stations for communities of a couple of thousand that are largely inaccessible by land.)
