Sure, I'm not quite sure how near you want them; there's Moncton (CYQM), Halifax (CYHZ)and St. John's(CYYT). That's about all I can think about right now. We use them as ETOPS-alternate for B767's. I'm not sure if you can use them for bigger planes, but as a fact I know a B767-300 actually landed at Moncton a few months ago.
Hope this helps,
Frank.
