In the season finale, the winners from each episode competed in a series of competitions for the title of "Canada's Smartest Person". The seven Gauntlet winners from the previous episodes were joined by a wildcard, determined by the Gauntlet loser who had accumulated the most points in their episode.

The fourth season of Canada's Smartest Person (officially entitled Canada's Smartest Person Junior) premiered on November 14, 2018. As the official title implies, the contestants are all preadolescent. Paul Sun-Hyung Lee hosted this season.

Unlike the previous three seasons which followed a knockout format, this season followed a traditional competitive reality television series format.

Each of the first three episodes began with a Speed Round, which consists of six small challenges in a rapid-fire succession. After the challenge, the lowest-scoring contestant was eliminated from the competition automatically and the highest-scoring contestant was deemed safe from elimination. Then, the remaining contestants were paired based on their rankings in the Speed Round (2nd place with 3rd place, 4th place with 5th place, etc.) and competed in a team challenge. After the challenge, all but the bottom two pairings were deemed safe from elimination. Afterwards, the remaining four contestants competed in a head-to-head challenge and the top two performers were deemed safe after the challenge. Finally, the remaining two contestants competed in the Ultimate Elimination round, which consists of various sudden-death challenges that two contestants compete head-to-head in. Once a contestant won three rounds, that contestant was deemed safe and the other was eliminated from the competition.

The fourth episode also began with a Speed Round, but unlike the first three episodes, the highest-scoring contestant was not deemed safe from elimination after the challenge. Then, the remaining contestants competed in a head-to-head challenge instead of a team challenge. After the challenge, only the highest-scoring contestant was deemed safe from elimination. The latter two challenges of the episode proceeded the same way that the latter two challenges of the first three did.

The fifth episode was a Redemption episode in which the first eight eliminated contestants were given a chance to return to the competition and qualify for the finale as a result. Like usual, the episode began with a Speed Round, but, after the challenge, the two lowest-scoring contestants were eliminated from the Redemption episode automatically and the highest-scoring contestant still had to compete in further challenges with the rest. Then, the remaining six contestants competed in a head-to-head challenge that, afterwards, would eliminate the two lowest-scoring contestants from the Redemption episode. Then, the remaining four contestants competed in a head-to-head challenge that, afterwards, would eliminate the lowest-scoring contestant from the Redemption episode and would return the highest-scoring contestant back into the competition. Finally, the remaining two contestants competed in the Ultimate Elimination round. The winner of the face-off returned to the competition and the other was eliminated from the Redemption episode.

The sixth and final episode consisted of five head-to-head challenges in which, after each one, the lowest-scoring contestant would be eliminated from the competition. The last of these challenges was the Super Gauntlet, a Canada's Smartest Person classic, which resulted in Mateus Soto being declared the winner of Canada's Smartest Person Junior.
