I like the trio, RR. The Opinel should be a great fine work knife, the F1 useful for many applications and the machete good for slicing, scraping, and chopping.
My single concern, given your geographic location, is the machete - are you going to need to chop or cut through hardwoods? If so, the machete may not be up to the task. Now, I've never handled an Ontario -made sample, and it could very well be much more stout and stiff than I imagine. However, I believe a hatchet or folding saw would probably be a better dedicated hardwood tool.
That being said, though, you're camping by a lake and seem to have a good idea of what you're getting into, so I think the tools should work. If it was me in your place, I'd still carry along a trusted, big chopper in my pack,
just in case. Ya never know what you'll need...
I applaud your idea of testing quality, inexpensive tools in the woods. Have a great trip
