Canada is a country that neighbours most of the United States to the north. It is where Robin Scherbatsky was born and raised in. Throughout the series, the country has been a constant subject of mockery by the American members of the Gang, especially Barney, who is revealed in Season 7 to have 1/4 Canadian blood due to his paternal grandfather's origins. The Gang has portrayed Canada as much more backward than the United States. Robin often mentions Canadian people, ideas, customs, etc that other members of the Gang are not likely to be familiar with. Sometimes, Robin is seen hanging out in Hoser Hut, a Canadian-themed bar in New York.

Notes and Trivia
- The character that plays Robin, Cobie Smulders, is Canadian in real life.
- Producers originally meant for Robin to be from Toronto but changed it to Vancouver. 
- In an interview with George Stroumboulopoulos, Smulders revealed that one of the show's writers is also Canadian, specifically from Guelph.  One of the show's co-creators, Craig Thomas, said in an interview with website Canadian of the Week that a lot of the specific Canadian references are from staff writer Chuck Tatham.
- On 6 December 2017, Smulders posted on her Instagram account that she made her own Robin Sparkles-themed Tim Hortons doughnuts. 
- Tim Hortons also actually happens to have several branches in the New York metro area and other parts of the US.
- The 'actual' and 'fictionalised'/'movie' versions of Stella, Sarah Chalke and Malin Akerman respectively, are both Canadians. However, unlike other Candian guest stars who appeared or were mentioned in the series, neither actresses' Canadian citizenship was alluded to at all. The character Stella is instead portrayed as someone from New Jersey.
- Although Katie Scherbatsky is Robin's sister, her nationality was never explicitly mentioned. Given that Robin's and Katie's mother is British, it technically remains unclear whether Katie is Canadian.
- Katie is shown to share Robin's love for hockey and calling her and Lily "Hosers" in Daisy.
- The name of Robin's childhood dog, Sir Scratchewan, is an obvious play on the word Saskatchewan, a province in central Canada.
- The highest point in Canada is actually not Mount Waddington as Robin pointed out in Dowisetrepla. It is actually Mount Logan in Yukon.
