Canada's laws around this are...odd.
The law prohibits ads from simultaneously naming a prescription drug and its therapeutic use. So you might see an ad pushing a specific drug, but it will never say what it's used for. Or you might see an ad where people talk about treatments for a condition but never mention the drug, just saying talk to your doctor.
Sometimes they get around this subtly. In one ad a number of overweight actors discuss how much they love a specific drug, but it's never mentioned what it's for but is implied.
And of course when US channels are simulcast in Canada, US ads just run as is.
I like the one where they're in a coffee shop or whatever and everytime they talk about the indications, there's a noisy machine running.
Much better than the one where everybody is like I asked my doctor about Flugeltrophen.
