The tournament is currently the largest tournament in Canada in terms of top-level talent, with 8 of the SSBMRank 2022's top 10 players and 17 out of OrionRank 2022's top 20 players in attendance.

Ultimate
The tournament was the first Canadian tournament to reach the "Premier" tier on the UltRank 2023 - the highest tournament tier on the ranking - as well as the third tournament to reach it that season. However, the tournament's tier was threatened following the dropouts of several high-profile players, most notably - who could not obtain a Canadian visa in time. - and - who did not realize his pool started on Friday; the dropouts initially dropped the tournament under the Premier tier threshold. The tournament's "Premier" status was ultimately saved thanks to #58 seed 's performance, as he upset #10 seed 3-0 (upset factor 5) en route to a 9th-place finish. This placement initially gave Armadillo a player point value of 50 on UltRank 2023, which bumped the tournament's score over the Premier tier threshold.

Aside from Armadillo, other notable runs include ones from #20 seed and #15 seed. In regards to the former, although he struggled against the Aegis throughout 2022, Zomba upset #4 seed 's Aegis 3-1 (upset factor 5); the subsequent confrontation on Twitter sparked beef between the two players that would carry over to their next supermajor appearance. Zomba also defeated #3 seed (upset factor 6) prior to Top 8, marking Zomba's first victory over Tweek outside of weeklies and eliminating Tweek at 9th. Ultimately, Zomba placed 7th, his first Top 8 finish at a North American supermajor in 2023 after falling just short of it at his previous few. In regards to the latter, kameme was initially sent to the Loser's bracket by, but then went on a long Loser's run, eliminating many players along his way, including at 13th, which marked the first time MkLeo placed in the double digits at a North American major; and #5 seed  at 5th (upset factor 4). Kameme ultimately finished 4th, tying his run at as his best performance at a supermajor since his character swap.

Finally, this tournament further widened the gap between the season's top 2 players - and  - and the rest of the season's top 5, as both players ultimately met each other in both Winner's Finals and Grand Finals. However, acola continued to struggle against Sparg0, choosing to use the Aegis and in both sets instead of his main. Sparg0 ultimately defeated acola 3-1 in Winner's Finals and 3-0 in Grand Finals, securing his second premier victory of the UltRank 2023 season and tightening the race for the #1 position for the first half of the year.
