Looks like Canadian gamers can't get enough of the Legend of Zelda or Pokemon franchises. According to an interview with Reggie Fils-Aime, Canada has a real affinity for two of Nintendo's biggest brands.
“The Canadian audience is the very tip of the mountaintop when it comes to Zelda games. There are certain franchises that overperform in the Canadian market. Legend of Zelda is one. I can’t tell you why but the Canadian consumer loves it. Every single game in the series has done better with the Canadian audience than the U.S. audience, and the U.S. audience does better than Europe or Japan. Another phenomenon, and this is a recent trend, over the last 10 years is Pokémon. Pokémon games do exceptionally well (in Canada).”
