Early career

Ayer began skating around 2007. He competed in only domestic events with his first three partners: Taylor Yanke, Nicola Salimova, and Jolie Che. Ayer and Che split at the end of the summer in 2017, and he spent about a year trying out with various partners before teaming up with Fabbri. He relocated from Calgary to Montreal to train full-time with Fabbri.^[1]

2018–2019 season: New partnership

Fabbri/Ayer were assigned to two Junior Grand Prix events in their first season together. They placed fourth at 2018 JGP Slovakia and seventh at 2018 JGP Slovenia.

Fabbri/Ayer placed second at the 2019 Canadian Championships behind Marjorie Lajoie / Zachary Lagha. Together, they were named to the Canadian team for the 2019 World Junior Championships in Zagreb, Croatia.^[2] At a tune-up event, the 2019 Bavarian Open, Fabbri/Ayer again won silver behind Lajoie/Lagha.^[3]

Fabbri/Ayer were thirteenth after the rhythm dance segment at the 2019 World Junior Championships but rallied with an eighth-place showing in the free dance to place ninth overall. Combined with Lajoie/Lagha's placement (first place), their rank qualified three ice dance spots for Canada at the 2020 World Junior Championships in Tallinn, Estonia.

2019–2020 season: New coaches

In July 2019, Fabbri/Ayer left coach Julien Lalonde to train with Marie-France Dubreuil, Patrice Lauzon, and Romain Haguenauer in Montreal.^[4] They made their senior international debut at the 2019 CS Warsaw Cup, where they placed sixth with personal bests in all segments.

2020–2021 season

Fabbri/Ayer were assigned to make their Grand Prix debut at the 2020 Skate Canada International, but the event was cancelled as a result of the coronavirus pandemic.^[5]

With the pandemic continuing to make it difficult to hold in-person events, Fabbri/Ayer competed at virtual domestic competitions, placing fifth at the 2021 Skate Canada Challenge. This result would have qualified them for the 2021 Canadian Championships, but they were cancelled due to the pandemic.^[6][7]

2021–2022 season

Fabbri/Ayer returned to international competition after almost two years at the 2021 CS Lombardia Trophy, placing twelfth.^[8] Given a second Challenger assignment, they were fifth at the 2021 CS Cup of Austria.^[9]

At the 2022 Canadian Championships, held in a bubble in Ottawa due to Omicron variant restrictions, Fabbri/Ayer finished in seventh place overall after being hampered by a fall in the closing seconds of their rhythm dance.^[9]

2022–2023 season

Skate Canada named Fabbri and Ayer to the senior national team for the first time in the lead-up to the new season.^[10] They ventured out internationally for the first time at the 2022 CS Budapest Trophy, where they finished in fourth place, 11.60 points behind bronze medalists Wolfkostin/Chen of the United States. Ayer assessed that they had given a "really strong performance in the rhythm dance and connected with the crowd," though faulting themselves for a free dance error.^[11] They were then invited to finally make the Grand Prix debut and came eighth at the 2022 MK John Wilson Trophy.^[12] Ayer dislocated his shoulder in the practice sessions at the Wilson Trophy and, while they were able to finish the event by making modifications to their program, it was subsequently determined that he required surgery. As a result, they withdrew from the 2023 Canadian Championships.^[13]

2023–2024 season

Following Ayer's recovery, Fabbri/Ayer started the season at the 2023 CS Nebelhorn Trophy, coming ninth.^[14] They were given one Grand Prix assignment, the 2023 Skate Canada International, where they placed seventh.^[15]

Fabbri/Ayer won the silver medal at the Skate Canada Challenge, the final qualifier to the 2024 Canadian Championships.^[16] In advance of the championships, defending silver medalists Lajoie/Lagha withdrew due to Lajoie entering concussion protocol, whilst reigning champions Fournier Beaudry/Sørensen withdrew after the latter was revealed to be under investigation for sexual assault. The ice dance podium was thus considered more open than in recent years.^[17] Fabbri/Ayer won the bronze medal, reaching the senior national podium for the first time.^[18]
