[3] Following the Youth Olympics, coach Andrew Evans announced that Toste would be retiring to focus on attending university while McIntosh would search for a new partner.

[6] There being no international season to speak of for Canadian skaters, McIntosh/Mimar competed as seniors on the domestic level, debuting at the Ontario Sectionals to win the gold medal.

At the 2021 Skate Canada Challenge, held virtually across several hub locations to minimize gatherings, they placed fourth, qualifying to the national championships.

[9] They went on to finish the season at the 2022 World Junior Championships, which had originally been scheduled to be held in Sofia in the traditional early March period.

[13] They were third in the free skate, despite McIntosh falling on her triple Salchow attempt and a shaky jump combination from Mimar, and won the bronze medal overall.

"[14] With the Russian ban continuing into the new season, McIntosh and Mimar made their senior international debut in a very open pairs field.

Mimar noted the event as a "new experience" and assessed that "our free wasn't the best we could do, after a good short, but we are still happy with third place.

[18] At their second assignment, the 2022 NHK Trophy in Sapporo, they placed third in the short program despite a minor throw error and set a new personal best in that segment.

The team won the bronze medal, their first on the Grand Prix, with Mimar saying that he was "very proud of my partner that she fought until then end despite a fall."

[25] McIntosh and Mimar were hampered by injury in the lead-up to the season, being able to train heavily only in the final three weeks before their first competition, the 2023 Finlandia Trophy.

[29] It was subsequently announced that the pair would split their time training under Nolan Seegert in Berlin, Dmitri Savin and Fedor Klimov in Sochi, and Bruno Marcotte in Oakville, Ontario.

[32] The pair were subsequently named to the 2025 World Championships team on the condition that they are able to earn the minimum technical element scores.
