The Brûleurs de Montréal Burners for the past two years have thrown an event known as taBURNak! as a welcome home for people returning from Burning Man and as an introduction and celebration of that unique culture of the playa. taBURNak! is typically held in late October/early November. Tickets have sold out every time so watch this space for announcements about this year’s event, or better yet subscribe to the mailing list.
A few years ago Montreal Burners held a regional event in the woods of Quebec called Ignition!
Smaller impromptu and organized events also happen throughout the year like Buckyday, SantaCon and others.
Every month, typically the second Tuesday is a gathering of local Burners, often at a potluck, picnic or bar. Look here.
