At your size and requirements you might have to DIY. Specialized sells their AWOL Expert frameset retail about $1000. Not sure Canadian cost but I do know their dealers tend to sell Specialized frames at pretty good discounts. I got mine for $725.

Top tube for XL is 625, reach is generous 409, and stack is almost too high at 660. "Swinger" dropouts are designed for just about any drivetrain one could imagine, including belt drive. Full steel frame including fork with generous rack/fender/bottle mounts.

My size large rides nice although it's not the lightest bike I could have built. Color is butt-ugly unless you love primer brown. I have an XL that I built with a flat bar setup. It's a bit long for me but I have a lot of stem length to play with to dial in my fit.

You didn't say whether a DIY was something you'd consider, but at your (our) end of the size spectrum choices are hard to find.
