Hamilton technically would be the easiest place to put a team, if a team had to move their tomorrow. They have Copps Coliseum, they have a largely populated city, they have hockey history. However there's tons wrong with a team moving to Hamilton. The OHL has failed there twice, the arena is much to big for even AHL hockey, the area doesn't even really support the Bulldogs that well. Those are just a few unsearched thoughts.
Cornwall has an arena very close to ready, technically I see know reason why a team couldn't play there tomorrow. But the Cornwall Civic Complex isn't exactly ideal for an OHL team as it sits, capacity wise its fine, but amenities need upgrades, dressing room, ect ect. Although as I said as it sits now it would be doable in the short term.
Thunder Bay other then logistical problems would be ideal, the Fort Williams Gardens holds just under 5,000 people, plus standing room I believe. Its an OHL calibre rink, renovated in 1995, could use more to become more OHL ready, however it could definitely be home to an OHL team tomorrow while upgrades where considered or completed.
The McIntyre Community arena in Timmins, it holds only around 1300-1500 people, while it has an excellent feel for junior hockey its much to small for the OHL. 20 years ago it would be ideal, now not even close.
Chatham and Woodstock don't have rinks.
Buffalo, New York or a place like Syracuse, New York may also be considered, with Buffalo being the more likely. Keep in mind both cities have or had OJHL teams in the past. An OHL team would likely start off playing at the First Niagara Centre, but like we saw with the 67's the past two years, OHL teams in NHL rinks just don't work.
Would their be interest in putting a team in the Scarborough/Pickering area.. The Generals could object, the Wexford Raiders had success for a long time, but had to cease operations about 5/6 years ago. No arena presently available. Unlikely, but just spit balling
The Town of Markham wanted to build an NHL rink in hopes of bringing an NHL team to town, would they consider building a rink for an OHL team ? Would they even Draw ? The Markham Waxers where a proud Tier two Junior Organization for many years, from 1930 until 2012 to be exact. Many NHLer's went through Markham, Steve Thomas, Adam Oates just off the top of my head. They had an ideal Tier 2 Rink, in the Markham Centennial Centre which held just under 2500. They also had a fairly successful team for a number of years, yet still.. know one attended games.
North York, with the North York Rangers, Toronto Canadiens, Toronto Lake Shore Patriots, all playing within 15/20 minutes of one another, would the area be able to support one OHL team. The Herb Carnegie arena hosted the Toronto Marlboros back in the day, but is by know means an OHL calibre rink.
Newmarket, the Ray Twinney Sports Complex was where the Newmarket Saints AHL club played and the Newmarket Royals OHL club played. It holds just under 4000 people, but, it needs upgrades for an OHL team. The club wasn't successful in its brief stay in the OHL back in the early 90's, but if the rink did get upgrades the growing population in the area could probably support an OHL team. Granted I say this without any research of the area done or looking into finer details.
