"D'oh Canada" is the 21st episode of the thirtieth season of the American animated sitcom The Simpsons, and the 660th episode overall. It aired in the United States on Fox on April 28, 2019. The title of the episode is a play on the national anthem O Canada.
The Simpson family is at the Mt. Splashmore water park, in line to ride the water slide, when Homer suddenly hustles the family out of the park.
Homer has earned two million soon-to-expire hotel rewards loyalty points, and takes them to Niagara Falls, traveling through upstate New York. At the falls, Lisa accidentally plunges over the falls while roughhousing with Bart, and is rescued by a Canadian Mountie.
Lisa is taken to a hospital, where she is kept for observation. Homer balks at the cost, but is reminded that Canadian healthcare is free. Lisa starts to rant to the Mountie about America, and is declared a political refugee.
With the help of Bart and Homer, Lisa and Marge sneak across a frozen river back to the United States.
Dennis Perkins of The A.V. Club gave the episode a B-, stating, "’D’oh Canada’ wants to skewer its targets on the American side of the border by having Lisa’s infatuation with all things Canadian (politeness, a hunky young Prime Minister, mounties with handsome horses, cape-wearing rescue beavers, free healthcare, schools that put on thought-provoking productions of Canadian literary legend Margaret Atwood’s The Handmaid's Tale) focus the show’s barbs more sharply and directly than usual."
"D'oh Canada" scored a 0.8 rating with a 4 share and was watched by 1.93 million people.
The musical mock salute to upstate New York drew substantial attention from the natives of that area, including a response from the New York State Republican Committee blaming the policies of Andrew Cuomo for making the region a laughingstock and a fact check from the Rochester Democrat and Chronicle, which concluded most of the claims were true but that some (such as Fox News viewership and disability claims) were misleading or unprovable. The Great New York State Fair responded that they were taking the song in jest but would invite the writers to the fair to allow them to see the area in person.
The episode came under fire in late April 2019 for offending some people. While the episode mocked American and Canadian heads of state Donald Trump and Justin Trudeau and brought up the SNC-Lavalin affair, the aspects that caused offense were largely related to a Frank Sinatra parody song where Homer made fun of Upstate New York and for the use of the slur "newfie" in relation to Canadian residents of Newfoundland. In the latter several Canadian children chime "stupid newfies" before a character closely resembling Ralph Wiggum calls himself one and proceeds to beat a baby seal pup plush toy with a club while singing about being a Newfoundlander.. Musician Bruce Moss rejected an offer from the show's producers to use his song "The Islander" for the episode, referring to them as "morally bankrupt" and turning down $20,000 US.
