I'm almost certain there will be flat beds on YYZ-YVR. AC runs a number of internaitonal configured 763's that are "direct" flights from YYZ to Asia/Australia that stop in YVR to disgorge transcon passengers and pick up transpac. I see no reason why these flights will stop when the 767's are refurbed (or 787's arrive for that matter). These flgihts will continue to make sense where AC is not confident of their ability to fill the aircraft on the transpac non-stop from YYZ.

The only problem is that the transcons with the 763's are not at the time of day when people really would want to use the lie flat feature.
