Based on his other posts, the OP seems to be finding a lot of bicycles that aren't well suited for grand touring. So, I went to Kijiji Montreal and without going through the thousands of bicycle listings, I simply searched on "Touring". Most weren't grand touring bicycles and those that were, are too small for the OP's 5'11" height, with one exception, a Velosport Alpin.
This is a true grand touring frame. It has relatively slack angles and a longer wheelbase and chain stays. It accommodates two sets of water bottles and has eyelets for both racks and fenders. It even comes with fenders and two Blackburn racks. The frame appears to be Tange Mangaloy 2001 which was a double butted carbon-manganese alloy.
It does have a triple crankset, though it is swaged and it does have cantilever brakes. It appears to have been upgraded to indexing with a new rear derailleur and some cheap clamp-on shift levers. The pedals are touring appropiate quasi-platforms with toe clips and straps.
It appears to be the 1984 model, so the wheels would only be 27", which would make spares more difficult. Still, it's a good, mid-range, grand touring bicycle, that appears to be close to the OP's size and doesn't break the bank at $350 CDN, in what is an expensive market. It's been on the market for 1-1/2 months, so could probably be acquired at a discount. I think it is worth a visit to check out the condition and fit. It has the potential for being a great grand touring starter bicycle for the OP. However, I would ditch those shift levers for some bar end shift levers, to complete the transition.
