Fans mostly pair the two together because they are both snowy lands, both of them are mostly neglected by the other countries and they both love the sport of hockey.
In real life, both Canada and Russia compete with each other fiercely in ice hockey. And in 1972, the Summit Series, the Canadian men hockey team went against the Soviet Union team in a best out of eight game. In the last game, Canada won in overtime. In the Anime/Manga, Russia unknowingly sits on Canada. Fans have taken this to being a regular habit for him, and, have used this instance for situations in which Canada may 'get back' at Russia and see how he likes being sat on.
Russia and Canada also have a bilateral relationship with each other, beginning when the Soviet Union had established diplomatic relations with Canada on June 12, 1942. Canada is officially represented in Russia by an Embassy in Moscow as well as an Honorary Consulate in Vladivostok. The Russian Federation maintains an Embassy in Ottawa, two consulate generals (in Toronto and Montreal), and an Honorary Consulate in Vancouver.
