So you've just seen Deadpool 2 [1], and you're feeling proud of yourself for catching all of the movie quotes [2], X-men tie-ins [3], and cameos [4] littered throughout the film. However, if you couldn't quite put your finger on the significance behind the supermax prison for mutants known as the Ice Box [5], don't be too hard on yourself. While the name originates from a Marvel comic, the mention occurs in only one issue: Maverick Volume 2, Number 8 issued in April 1998 [6].

The Ice Box is located in the Arctic tundra of Canada's Northwest Territories. The remote locale is meant to act as a deterrent for the mutant detainees, and the prison's escapee record reflects as much. The only person to successfully break out of the structure is Sickle [7], the bodyguard to Russian mafia lord Ivan Pushkin [8]. Sickle is extracted by Ivan's ally, the Confessor [9], a former KGB operative turned mercenary who uses a pending snow storm to cover their escape.

Naturally, Deadpool 2 [10] takes quite a few liberties with the source material. The version of the Ice Box that Firefist (aka Russell "Rusty" Collins) [11] and Deadpool briefly occupy exists in a populated area and has the capability to convert into a heavily armored mobile unit. Even still, with Deadpool [12] and Ryan Reynolds [13] both being Canadian, using the name of a comic book prison based in the Great White North is definitely a cool reference.
