Let me first start by saying, I really don't want any team to move and screw it's fans. It sucks losing a team, and it sucks when an owner uses the threat of a move as leverage. That said, it is a conversation to be had here. First off, arena renovations of this scale don't happen overnight, so in a couple years this is a bit of a different conversation. As far as who? Well lets look at the bottom 8 team in terms of OHL attendance. My comments here aren't especially informed so if you have a better local perspective please share it and feel free to correct these comments.
North Bay - North Bay hasn't really had a deep run since moving from Brampton. This season coming up I think will be a big test but I think they can turn it around. It just strikes me as awfully soon to be moving them around.
Mississauga - The Steelheads are of course in this conversation after their current arena deal is done, which I believe is five year. Before then, it simply won't happen unless the city of Mississauga was asleep at the wheel during the arena deal and ownership was left with an escape clause. If the team hasn't turned a corner by then, I can see a move.
Flint - Flint I would say is probably the most likely, because to be honest, their owner has really shown some bad stripes. It was clear during his coaching scandal that is primary interest with the team was his kid getting minutes. What will happen when his kid is done with junior? I'll say this, he hasn't endeared himself to Flint and while they've been a basement dweller since inception, I think it will be interesting if they actually produce a competitive team. It's also pretty clear the league doesn't want another controversy coming out of Flint.
Sudbury - Sudbury is building a new arena for the Wolves and I'm to understand ownership may have a stake in the new arena. I'm very disinclined to think Sudbury is going anywhere any time soon.
Owen Sound - Really, Owen Sound doesn't belong on this list. Their average is a sellout average and many had said Owen Sound is the model of a small market franchise. The Attack aren't going anywhere.
Peterborough - Given the city council was looking at arena replacement and seems to fairly strongly believe in keeping the team in Peterborough, barring a massive sticker shock/municipal cleanout. I don't recall the last time Peterborough had a great team, and from my understanding attendance for the Pete's improved substantially this year.
Sarnia - I think the Sting are the sleeper here that no one is talking about. The team claims to have lost money and had attendance woes for some time and I believe and this season they were a top team in the west and it only bumped the attendance up by a couple hundred. I'm to understand their lease renewal comes up in two years as well.
Saginaw - The Spirit's attendance has declined a bit over the last few years, but I don't think to the point where a move is a serious consideration. I would think if Saginaw does end up moving, it would be after Flint has, but even then.
I think there is one last option that may present itself, and that's expansion. Cornwall I'm to understand has been pursuing a franchise for sometime, and Brantford coming in at the same time would balance the conferences.
