It is doable but would take a long time (which is not a bad thing if you have it). Don't know if you have radar, but until Quebec City, fog can be an issue and it can be cool even in July. As you likely know, fog is a problem on lake Superior too. The length of the trip and weather area a problem since you cannot start too soon but need lots of time.
Going up the St Lawrence is slow but you can use the tide until almost Three Rivers. We had one very long day where we carried the tide and did 103 miles in 18 hours. At one point we were doing 10.5 knots (upstream), but you really get used to doing 2.3 over the ground much of the time.
As was suggested, you have other options - going up the Hudson and returning down the St Lawrence makes sense but that would be a two summer trip as would going up the river if you intend to return. Another possibility would be trailer your boat to the lakes and sail it back. If you do not have a trailer you might be able to borrow or rent one. You might also be able to ship your boat to Ontario with one of the boat transport companies that is already taking a boat west and has room for your boat on the same trailer.
After the refit we have decided to sell Ainia. We want something smaller that would be could for the light summer winds of Lake Ontario, although we plan to spend at least a couple of winters in the Caribbean before heading north.
