Leaving out the resounding question of why they would do this could the British have built a Canal connecting Lake Superior to the Hudson Bay in the 1850's to 1900?
Series of canals along Nelson River which links lake Winnipeg to Hudson Bay. Then several along Winnipeg River gets us to lake of woods.You'd get more value from a canal linking Lake Winnipeg and Lake Superior.
You'd have to go Michipicoten - Wawa Lake - Hawk Lake - Hawk River - Whitefish Lake - Dog Lake - Crooked Lake - Missinaibi Lake - Missinaibi River - Moose River - James Bay.

Now several canals linking lake of woods and Lake Superior accomplished the task. Take a billion dollars at that time and couple hundred thousand lives.
Plus it would open up Manitoba, North Dakota and Minnesota to settlement earlier.That is an interesting Idea would accomplish the task and open up more traffic to Great lakes traffic.
Looking at some topo maps, going along the Lake Superior-Pigeon River-Boundary Waters-Rainy Lake/River then down doesn't seem too hard actually. The 800 feet elevation change from Lake Superior to Pigeon lakes source isn't exactly easy, but the Erie canal pulled off a total elevation change of 560 some feet, so the tech to do it is there. Still going to need locks on the way down to the Rainy River, and then probably some more down to the Lake of the Woods, but that opens up a huge area of the Minnesota-Ontario interior to travel to the Great Lakes. The lakes in the Boundary Waters are rather deep too, so you can get some pretty good sized ships on them if there was actually a way for them to get there. It wouldn't be a cheap proposition, but it seems doable.I have something similar (minus the Hudson Bay link) in a TL of mine. Go Lake Superior - St. Croix River (the Chippewa River might work too) - Mississippi River - Minnesota River - Red River - Lake Winnipeg. At that point you have the most usable portion complete since the Nelson River is full of rapids and can sail from New Orleans to Duluth to Winnipeg. Probably better than linking Lake Superior directly to Lake Winnipeg via the Rainy River - Lake of the Woods - Winnipeg River route.
It cost Britain 800,000 pounds and took six years to do the Rideau, and that was a military and economic necessity which was only 200km long.
That said, a large chunk of that cost was land acquisition, which isn't near as much an issue from say Winnipeg to Superior. The Nelson river portion is probably insane though. Huge and frequent drops in elevation, plus lots of rapids to deal with, and most of it is in Sub-Arctic conditions. Winnipeg to Superior on the otherhand wouldn't be a walk in the park, but apart from the Pigeon river portion, most of the route is probably easier than Rideau was. The Pigeon River section would need a couple 100 ft step locks, and that sure as hell won't be cheap or easy. Doable if there's a reason to though.I would say impossible. It cost Britain 800,000 pounds and took six years to do the Rideau, and that was a military and economic necessity which was only 200km long. What you're describing would be 10x as long with no local labour pool to draw from and through much harsher country and few logistical centers nearby for something that offers almost no benefit.
Britain would get much more from the Trent-Severn or even the more crazy French River-Georgian Bay proposal for a fraction of the cost.
usable a month or two a year? I guess during the loooooooong winter it could be used by ice road wagoneers.
On second thought, a canal at Thunder Bay going up the Kaministiquia-Matawin-Shebandowan to Shebandowan Lake is amost certainly easier than going through the Pigeon River Canyon (and it doesn't disturb that beauty). From there its a short canal to Lac des Mille Lacs and you go down Seine-Rainy Lake-Rainy River-Lake of the Woods-Winnipeg. Thunder Bay has a great natural harbour breaking bulk from canal ships to lakers so that's another plus. Significantly less dramatic rises in terrain as well, so its more viable earlier.That said, a large chunk of that cost was land acquisition, which isn't near as much an issue from say Winnipeg to Superior.

I don't think viable means what you think it means. Any canal west of the Great Lakes is the opposite of viable, you're going from edge of civilization into literal wilderness. Where are the workers coming from? What exactly is the point of the canal when rail is starting to come into play?On second thought, a canal at Thunder Bay going up the Kaministiquia-Matawin-Shebandowan to Shebandowan Lake is amost certainly easier than going through the Pigeon River Canyon (and it doesn't disturb that beauty).

That's kinda the point of canals in this era though, they open up the interior to civilization. The Mississippi tributaries in the great plains are in literal wilderness, but were channelized to open them to navigation and it directly led to development anywhere navigation was improved. A Winnipeg-Superior Canal does exactly that, it opens the interior for easier settlement. If you do it before the railroad craze starts in earnest it is indeed perfectly viable.I don't think viable means what you think it means.
