Most of the junior arenas in Quebec seem to be old barns and relatively small (except for Quebec City, I guess, which is still kinda old). 
  
Most OHL arenas now seem to be pretty new, the smaller, older ones are getting phased out (St. Mike's, the old arena in Sault Ste. Marie, Kingston).  Hell, London is supposed to be basically an NHL calibre arena, just a little smaller.
