At the start of the show, Andrew recalls an incident in the past year where a contestant on the Dutch equivalent of this series, De Allerslechtste Chauffeur van Nederland, injured host Ruben Nicolai and a cameraman during its shoulder check challenge, and how it has put him on edge (Canada's Worst Driver 7 was filmed as the Dutch series was airing in the Netherlands). The episode also opens with Tab and Afiya seeking help from Shyamala between episodes to address Tab driving anxiety and Afiya's lack of taking on responsibility.
The Snowplow Challenge – A Dodge Ram outfitted with a snowplow is used for this challenge. Contestants must proceed forward through a short course at 20 km/h (with wood chips being used in place of snow) without hitting any of the parked cars at the side of the course. Contestants have 30 minutes to attempt the course. Shyamala's counseling has paid off, with Tab passing the challenge after 7 minutes and Afiya after 17 attempts. Sly continues to be unaware that he hits things in his attempts; it is only when he looks far ahead that he passes (he had also sped up to 25 km/h in his successful run). Aaron is not confident going up to speed, and even under speed he hits things – due to the lack of looking far ahead. However, Aaron slowly begins to speed up, but time runs out before he can get off a successful run. As with previous challenges, Janis refuses to assist Shirley through her run despite her soliciting advice; and because of being forced to make her own decisions, Shirley passes.
Rules of the Road Test – The contestants are quizzed on rules of the road, with a special emphasis on road rules specific to various parts of Canada; such as regulations around right turn on red in Montreal (the only part of Canada where it is illegal, owing to unique safety issues) and stopping behind Toronto's streetcars (as Toronto's streetcars do not stop curbside, cars must stop behind a streetcar when its doors are open to allow passengers a safe place to embark and disembark from the sidewalk). Shirley is worst at 1/10, largely on the back of outdated knowledge.
Car Curling – As curling is a popular sport in Canada, this challenge is inspired by the amateur pastime. A Buick Skylark is used for this challenge. Contestants must push a large "rock" with the car and brake before reaching a "hog line", while the momentum of the rock carries it into a "house". The contestant closest to "the button" wins. Contestants have eight rocks to try to push into the house. In Shirley's attempts, she never gets comfortable getting up to speed without losing control of the rock, and she only gets two rocks to the hog line – both of which promptly stop a few feet past the line. Sly loses control in six of his eight rocks before reaching the hog line, and doesn't place any of the rocks in the house. In contrast, Afiya starts quickly and accelerates so fast, all of her rocks sail through the house; none of her eight rocks actually land within the house. Aaron also loses control of his rocks early on, and his timid driving and over-correcting for his errors does not get him any of his eight rocks in the house. Tab wins the competition when her first rock sails into the "four-foot" in the house.
Challenger Challenge: Swerve and Avoid – The challenge is themed around avoid avoiding moose on the road. This is a particular issue for Shirley, who has killed family pets due to not swerving to avoid them. In this year's version, contestants must clear the course at 70 km/h in the Challenger. Tab accelerates to 80 km/h, and in trying to slow down she does not have enough time to get back down – and hits the barriers, destroying the front bumper. In her second attempt, she swerves too wide... and destroys the back bumper. Tab does, however, clear the course in her third attempt. Aaron passes the challenge on his first try. Shirley swerves too early in her first two runs, and hits the last lane marker. She clears the course in the third attempt. Afiya fails the course, as she goes over-speed and hits the moose in her first run. She swerves too early in the second attempt, and too late in the third. Sly accelerates to 100 km/h, and goes straight ahead and brakes, destroying the centre of the course. The challenge is aborted then – as Andrew remarks that he could not have done the challenge any worse.
The experts commend Tab and Shirley on their improved behaviour, and both claim that they deserve to graduate. However, Afiya admits to being overconfident when she entered rehab, and the realization of the true nature of her driving skills means that she is not ready to graduate. As for Aaron, he feels that his moment has still not arrived. Sly admits to not making any ground so far through rehabilitation. Cam believes that Tab should be the graduate – while Philippe still has an issue with Tab driving too fast, so he endorses Shirley. The experts, in a 3-2 split decision (Shyamala backing Shirley and Peter backing Tab) choose Tab over Shirley to graduate – as Shirley's driving was still too inconsistent for the experts' tastes.
