It's been a while since I've been up there (lived in Montreal for many years), but I can't really think of anything like that.
They do have a history of trapping and logging. I remember hearing about a lumberjack camp/museum in Shawinigan, which is just a few miles north of Trois-Rivières. Never been there, but it's supposed to be nice. There are also "sugar shacks" (cabanes à sucres or érablières) all over the place. But that's more woodsy stuff rather than knife-related.
I also remember some stores selling goods made by some of the Indigenous people. I've seen some interesting, handmade knives for sale in some of them.
