OS has flights from 3 East Cost / Canadian Gateways (YYZ, IAD; JFK) - they fly 767s and will get refurbished, full-flat C seats between Dec 2012 and April 2013. I believe IAD will receive the upgraded product in Jan, but better check. (Seating is a staggered 1-2-1/2-2-1, so can be easily identified).
IMHO soft product (service, food, drinks) are on par with other airlines' F. With the nw AVOD and seat it should make for a nice ride.
