D'oh Canada/References

==Cultural References==
*The name of this episode is a reference to the national anthem of Canada, "O Canada" which was performed in "The Bart of War" and sung by Ralph in "Das Bus".
*The episode references the incident where US President Donald Trump called Canadian PM Justin Trudeau "very dishonest and weak" following a G7 meeting in 2018.
*Lisa saying "please not Ottawa" when she is granted her own hockey team is a reference to the fact that the Ottawa Senators NHL team finished last in the 2018-19 NHL season, posting a 29-47-6 record.
* Several defunct retailers are mentioned and/or seen:
**Toys 'Я' Us
**Sears & Roebuck
**Circuit City
*The following mascots are seen in the episode:
**Otto, the Syracuse Orange mascot
**Roni the Raccoon, the 1980 Winter Olympics (Lake Placid) mascot
**A borscht jar. Borscht is a sour soup made with beetroots that originated in Eastern Europe. The mascot references the "Borscht Belt," which consisted of parts of Orange, Sullivan, and Ulster counties in New York. The Borscht Belt was a popular vacation spot for Jewish families during the 1920s through the 1970s.
**A dime
**Opioid pill
**A scratch-off lottery ticket
*A sign outside Lisa's foster home says "Give us your Alec Baldwins, your Lena Dunhams, yearning to breathe free." This is a reference to both those celebrities saying they would move to Canada if Donald Trump became president. The wording is a reference to the poem 'The New Colossus' found on the Statue of Liberty.
==Trivia==
*The "Will you take us to Mt. Splashmore?" quote from "Brush with Greatness" is mentioned by Bart and Lisa in this episode.
*The episode's production number is the license plate number of the car which Marge gets into upon crossing into Canada. Part of the number is obscured by rust.
*A Canadian version of Ralph Wiggum is seen in Canada.
**Groups of people protested this episode due to the satire of upstate New York and making fun of Newfoundlanders with Canadian Ralph Wiggum wearing a seal pup hat. 
***The robot baby seal/robopet he breaks and then wears as a hat is the same one that was seen as part of Bart and Martin Prince's science fair project from "Replaceable You".
*Dewey Largo mentions to his music class that they have been working on the same song for thirty years, referencing the Opening Sequence.
==Goofs== 
*Homer shouldn't be allowed in Canada as he was banned from the country in "Midnight Rx".
**Though the ban may have been lifted a while after the events of "Midnight Rx", because Homer returned to Canada in "Boy Meets Curl" and didn't get in trouble.
*In Canada, free universal healthcare is only available to Canadian citizens or permanent residents. As Lisa Simpson is neither, she would not qualify for free healthcare in Canada, and will need to pay a hefty medical bill for her hospital stay.
**Also, in "The Bart Wants What It Wants", Homer already knew that the medical healthcare is free in Canada, but in this episode he is surprised to learn it. Though he might have forgotten that.
*In Lisa's discussion with her foster family, five restaurants are mentioned: Harvey's, Swiss Chalet, Mr. Submarine (which has actually been known as Mr. Sub since the 1990s), Earls, and Humpty's. Lisa entered Canada in Niagara Falls, Ontario, and re-enters the United States by walking across the Detroit River from Windsor, Ontario to Detroit. Though Harvey's, Swiss Chalet, and Mr. Sub are national chains primarily based in Ontario, Humpty's is found exclusively in the western provinces (Manitoba, Saskatchewan, Alberta, and British Columbia). Earls is also primarily found on in the west, with only 4 of its 68 locations found in Ontario (fewer than its 10 locations in 7 US states).
