"It's Christmas in Canada" is the fifteenth and final episode of Season Seven, and the 111th overall episode of South Park. It aired on December 17, 2003.
The Brovlofski family is dealt a devastating blow when Ike'sCanadian birth parents show up unexpectedly, and want their baby back. When the townspeople decide to forego Christmas gifts and take up a collection to get Ike home to South Park, the boys are distraught. Before all the money for their Christmas presents gets spent, they hightail it to Canada to bring Ike home themselves.
It is a few weeks until Christmas. At the Broflovski Residence, the entire family is celebrating Hanukkah together. Gerald joyfully notes how much the family's togetherness means at this time of year, and that nothing can break them apart.
Seconds later, the doorbell rings, and Gerald answers. At the door is a Canadian couple; who introduce themselves as Harry and Elise Gintz. Just as Harry begins to calmly explain why they have sought out the Broflovskis, Kyle and Ike walk into view to see who is at the door. Elise, calm and not saying the word until this moment, immediately screams "Peter!" and rushes in to hug Ike, who, frightened, takes cover behind Kyle.
While in discussion in the dining area, with Kyle and Ike outside listening in, Harry and Elise reveal they are Ike's (or address him as his birth name "Peter"'s) biological parents, who, having given Ike up for adoption at a turbulent time in Canada, have steadily regretted their decision as time went on. Initially, it is assumed the Gintz's are here to visit Ike, and Gerald gently asks them not to do so again for fear of emotionally hurting Ike, but it turns out the Gintz's want to take Ike back home to his birth country, Canada. The couples begin to argue, with Harry justifying their right to change their mind about putting Ike up for adoption as, due to a new law made by the Prime Minister of Canada, all Canadian-born children in America must be returned. The Gintz's depart, with the Broflovskis vowing to fight them in court.
Sadly, the Canadian law is legal and cannot be overturned by South Park's court, so Ike is remanded to the custody of his biological parents, devastating Gerald and Sheila. Ike then leaves the next day with his biological parents.
Two weeks later, Kyle notices his parents steadily getting worse as time goes on without Ike like Sheila walking around the house like a zombie and Gerald cannot stop crying. Kyle attempts to get his friends to help him, however they have other things on their minds; Cartman selfishly believes that presents are more important, Stan is obsessed with the Christmas adventures that he may have this year, and Kenny, while he doesn't verbally explain why he doesn't want to go, may believe that he will die again, as mentioned later in the episode.
In the wake of this incident, however, South Park's citizens decide to brotherly to the Broflovskis and, in an effort to aid them in their attempts to reach the Prime Minister and convince him to allow Ike to return to America, they will give them their Christmas gift money. However, they clearly did not take their children into account when they made this decision, and as such, all the children are left upset with the thought of Christmas without any presents (Clyde bursts into tears at the news). Most especially is Cartman, who is outraged and (naturally) blames it all on Kyle since his family is being given money. Cartman finally reaches his breaking point and prepares to fight Kyle, but Kyle has an idea of how to save Christmas: the boys can go to Canada and get Ike back themselves in the few days before Christmas, saving everybody's money for presents. Cartman calms down and agrees, but promises that he will fight him if they don't get back home in time.
They fly with City Airlines, run by City Wok owner Tuong Lu Kim (it is thought that the word "city" was used because it sounds like "shitty" when said in a Chinese accent, and Tuong is quoted saying, "enjoy your city flight!" while it sounds like he is saying "shitty fright"). Cartman and Kenny don't want to fly the moment they see the single engine Cessna they are expected to fly in; Cartman because he does not trust the Cessna, and Kenny because, as he says in a muffled voice, "Cause dude, I'll fuckin' die!" Stan convinces them both by reminding them that they both care about Christmas. Cartman, who only cares about presents, exclaims, "Of course I care about Christmas!" but then is forced to come. During the flight, the plane suffers from mechanical troubles, not helped by the fact that Tuong falls asleep and flies further than he was intending without him noticing. He parachutes out of the plane, leaving the four boys alone in it. It crashes in Canada, but the four boys get out completely unharmed. In Canada, they meet a bunch of Canadians, including Scott, a Canadian who is "a dick". He hates both Americans and Canadians, and vows to stop them from meeting the prime minister.
Traveling to the capital on the "only road" in Canada, the boys meet others plagued by the new Prime Minister's laws - a Mountie named Rick, who is forced to ride a sheep instead of a horse because his funding has been cut; an unnamed French Canadian mime, who can no longer drink wine; and a Newfoundlander named Steve, who can no longer practice sodomy. In Newfoundland, Steve points out, to the boys' horror, that they were heading in the wrong direction, but the group get to the capital in Steve's boat.
In the Center Block of the Parliament Buildings, where the boys convince the guard to let them in by crying, the boys finally meet with the Prime Minister; who is a gigantic floating head. Scott then arrives with the Gintz's. Scott and Kyle both appeal to the Prime Minister to support their separate views, with Kyle making a more impassioned and touching monologue that affects the Gintz's. The Prime Minister, however, is a brutal dictator, and refuses to repeal his laws, and, to prove his point, vaporizes Kenny. While the Prime Minister rants, Stan spots a curtain in the corner, and pulls it back to reveal the gigantic floating head is mechanically controlled by Saddam Hussein in a spider-hole. Upon discovery of the Prime Minister's true identity, the Canadians arrest Saddam and declare all of the new laws null and void. The Gintz's, touched by Kyle's dedication and the amount of love he has shown their son by coming all the way to Canada to get him back admit they were wrong into taking Ike back, give Ike the choice to go back to his home in Colorado. Ike accepts, and the Gintz's are left happy that their son is in the care of a family that loves him.
Suddenly Cartman's watch beeps; it's Christmas Day. Cartman is shocked about missing Christmas, but Kyle insists that he got his brother back and that's all that matters. Cartman however gets angry and thirsts for a fight. Kyle finally agrees and, very reluctantly, hits Cartman, once, with a simple punch to the nose. Cartman immediately breaks down, screaming and bawling at the top of his voice and call for his mother in his accent.
Rick the Mountie then comes back in inviting the boys to celebrate Christmas Canadian-style, being part of a parade, celebrating Saddam's capture and the boys efforts to de-power him. Oblivious (either unaware of unwilling to realize it) to what has transpired, Stan is the only one unhappy, he sighs and says that maybe they'll have a Christmas adventure next year.
