According to Gilles Courteau, the Avenir Centre is the best "purpose built" Major Junior Hockey arena in Canada.
He says that CHL teams in Quebec City, Edmonton and Calgary may play in larger buildings with similar capabilities, that those arenas were built with the "NHL in mind". Of the rest, according to Courteau, the Avenir Centre has no equal in the land.
Further, in terms of QMJHL arenas capable of hosting the Memorial Cup, there are currently only five - Halifax, Moncton, Saint John, Shawinigan and Quebec City. Gatineau will join the list when their new arena in built in 2022.
So, Halifax is hosting this year (2019). The earliest Moncton can hope to host the Mem Cup is 2022. Shawinigan hosted not long ago, and I think Moncton will have a leg up on Gatineau. This means our competition will be QC and SJ. Both of these cities deserve to host the cup too, so the competition will be tough. I'm pretty sure though that Moncton will host the tournament again in 2022, 2025 or 2028. I'm banking on sooner than later, especially with the Avenir Centre being a showcase facility.
