Canadian Highlander isn't specific to Canada (specifically Victoria, British Columbia). That's simply where it was invented by fans (sixteen years ago) and where it continues to flourish.

1. It's a singleton format, which means that outside of basic lands, you can only play one copy of each card in your deck.
2. You play with a minimum of 100 cards.
3. You play with 20 life, and you duel one-on-one only. No multiplayer here.
4. There are no sideboards.
5. There are no commanders or any other color restrictions.
6. It isn't an official Wizards format. It's a fan-made format that maintains its own rules and lists.

​Canadian Highlander uses the Vintage banned list


The first thing that may come to your mind when you think of a Vintage banned and restricted list is that Vintage has the most powerful cards available in Magic. They don't even ban cards for power-level reasons in Vintage! And you would be correct.

The next thing you may be thinking is that if everyone gets to play with all of these super powerful cards from Magic's beginnings, then the format must be pretty degenerate. Combos, turn-one kills, that kind of thing.

While your instincts are correct, it doesn't play out that way for two main reasons:

The first is simple; we are talking about 100-card (typically, although you can use more if you'd like) singleton decks here. It's pretty hard to set up consistent combos or turn-one kills when you have to go that deep into the card pool. The nature of big singleton decks leads to games that don't resemble one another when played out (which is great).

The second is the most important and defining thing about Canadian Highlander, and it's called the points list.

The points list is an ingenious way to manage a format like this. It's pretty simple, too. The points list gives a point value to certain high-power-level cards, and you get a certain number of points (10 per 100 cards in your deck) to "spend" per deck.
