If you want to pick up a 64-ounce jug of beer, also known as a growler, it is possible in Toronto, though don’t expect to do this at the LCBO or Beer Store. I recommend checking out this very good article from the Torontoist on where to find growler beer in Toronto. Most points of purchase will either charge a high price for the first order but offer discounted refills, or they will charge a deposit of around $4 for the growler.
Also, tonight, I saw it with my own eyes, Bud Light Platinum is available in Canada. A 6% version of Bud “Light” isn’t something I’m excited about, but I would try it once, likely in a bar establishment where I don’t have to purchase more than one at a time.
