Helloi Peekawho, I live in Alberta Canada. The medication you're referring to is commonly called Tylenol 1 here, or a generic Tylenol 1 is also available. My understanding of the dose is that it's about 1/3 the strength of Tylenol 3. It can be bought over the counter here in Alberta, although ALL pharmacies do keep track of who buys it, what quantity & how often, and share the information with each other. In BC & the Yukon it's sold OTC with no records kept.
