Lake of Bays Brewing Company Limited has some vegan options

Company email (April 2020)

"Both our Paddle On & Starboard are vegan. Our Peach Paradise was not vegan as it used lactose (milk) products. Our products are only bottled and manufactured at our brewery in Baysville, ON."

Company email (July 2012):
"Our beer contains malted barley, hops, yeast and water. We use mineral salts to adjust the profile of our water and put something called Irish moss (brown seaweed, or carrageenan) into our beer during the boil to help clarify it - this is all removed prior to filtration. No gelatin or isinglass in our beer, with the exception of our cask beers, where we sometimes use isinglass as a clarifying agent. So, all in all, no animal ingredients that we're aware of (except for in the casks).

We make all our beer at our brewery up here in Baysville - no contract production elsewhere."
