No, I'm referring to the Canadian Flag Ugland ships... rugged north atlantic spec'd shuttle tankers, DP, bow loaders, rugged things that look like normal tankers until you get near one and comprehend the spec they're built to, in my opinion at least. The entire fleet isn't canadian flagged but mostly is. They run a lot of oil placentia, see them in pt Tupper and beyond. Once in a while do a bayway trip.
The Irving ships, which are really Kent Line ships, that are really managed by Vroon, are filipino and eastern european however some, if not the majority, of the captains are now Canadian citizens. The Acadian is Canadian top to bottom and sails internationally down to the states on occasion. Hornbeck, pre-genesis, had the Liberty service on a pretty stead St. John-New England run for a while but that's since over with. No reason why OSG, crowley or whoever wouldn't put a few of their ships on some of that work.
Yeah, definately not much domestic canadian tonnage, lot of chilean tugs i remember too. But they're still Canadian Flagged with Canadian crews, ultimately jobs for mariners and security are the concern; shipbuilding is another whole issue.
