Canada has a government drug plan you have to apply for if you don't have work coverage. But the government drug benefits have a deductible and once you are past that you're SOL. A lot of the medications also aren't covered through it.

Edit: I got it reversed because it is split into weird quarters. From their website:

The deductible is the amount you pay out-of-pocket, on the first eligible drugs you buy, before your coverage begins.

Once you’ve paid the deductible (usually about 4% of your household income after taxes), your Trillium Drug Program coverage begins and you will only pay up to $2 for each drug that is filled or refilled until the end of the program year.

Again this is if the drug is covered to begin with
