Canada's Worst Parking Lot – This challenge is only done once every two years. This year, contestants must park into the spaces by reversing. Initially, no spaces are available, and spaces will only open up as blocker cars move out. Aaron is the first to be penalized with a lap when he suddenly stops in the parking lot, and Shirley is penalized when Janis takes her steering wheel; no other penalties were assessed for the rest of the challenge. Aaron is the first to park after a brief encounter with a blocking cube truck and initially trying to give up the space; the cube truck is unable to park in the space and promptly moves out, prompting Aaron to try again. Sly is the second to park, though he is initially unsure as to whether he is between the lines until he stops. Tab is third to park, though she was "shaking somewhat" through her run. The last space is claimed by Afiya when she beats Shirley to the vacated space.
Parallel Parking – After a lesson on parallel parking (Sly getting written instructions as requested), the contestants must park a 1967 Chrysler Newport into a space. Contestants have 30 minutes to park, and must make only one parking attempt per trip through the course. Tab eventually passes in five attempts. Afiya demands silence, and – despite getting out of her seat to check the passenger side as she is reversing – passes on her first try. Andrew observes Sly from the backseat throughout his run; Sly spends two minutes to recognize where the wheels are, and another eight minutes to reverse – only to end up too far from the curb. He runs out of time, and fails. Aaron repeatedly solicits his father's advice, but though the advice is well-meaning, Aaron fails each attempt. When he demands silence, Aaron succeeds after two additional attempts. Similarly, Shirley solicits her daughter's advice. On Shirley's final attempt before running out of time, Janis adamantly refuses to assist her mother despite repeated solicitations – and Shirley passes as a result.
The Trough – The annual challenge consists of a simple course with two turns using the Toyota RAV4. Contestants will have 30 minutes to go through the course. Janis is repeatedly fed up with her mother's solicitation, and Shirley fails. Aaron passes on his last attempt before running out of time, again demanding silence from his father after being given bad advice in every previous run. Tab inches along in each run, but due to Matt's bad advice, Tab banishes him from the vehicle. She makes the first turn but fails the second turn as a result; and runs out of time. Afiya repeatedly falls off the course, and though she wants to quit after 20 minutes, she is convinced to go the entire 30 minutes. She fails on the last turn in her last attempt. Sly – in an ill-fated attempt to "gun it" through the second turn – causes severe damage to the underside of the SUV, ripping out the exhaust manifold and puncturing the fuel line when the rear wheel hops the rails. Tearing a hole in the RAV4's gas line was considered to have been impossible by the show's vehicle maintenance crew, and the challenge is thus aborted.
Challenger Challenge: Icy Corner – After a lesson on collision avoidance, the icy corner must be tackled at 50 km/h. Contestants have three attempts at the corner before failing. Sly releases the brake too late, and hits the wall in all three attempts. After this, Andrew voices his opinion that Sly's driving is showing no signs of improvement, and that he should seriously consider giving up driving permanently; a point which Andrew would continue to make until the end of the season. Tab goes over-speed (at 60 km/h) during all three of her runs, and hits the wall each time. Afiya brakes too soon and takes up the tarp in her first attempt, and hits the wall in her other two attempts. Shirley also pulls up the tarp too soon in her second attempt, and in all three attempts she does not release the brake and hit the wall. As for Aaron, he passes on his first try.
In deliberation, Afiya apologizes to Andrew for cursing at him after failing the Trough. Cam lashes out at Sly for "gunning it" during the Trough, while Shirley is confident that she deserves to graduate. Tab also feels confident in graduating even though she went over-speed in the icy corner. Aaron, the consensus best performer in the episode, believes that he also deserves to graduate based on his performance; but he would rather stay put, as he believes his moment has not arrived. Shirley and Tab are shortlisted by the experts, but Andrew is not confident in graduating either of them. As a result, no one graduates this episode.
