Thanks for that comment
Not going to open a can of worms here but I have visited Rice Lake for over thirty-five years let alone a few other places in Ontario, met thousands of people and not one time have I ever heard of a person from the states coming up to harvest fish to sell here, not going to say it has never happened but I never heard of it before.
Now I'll tell ya what I have witnessed, locals to cheap to rent a boat from a resort for the day and will pay a "minimal fee" to park their car and some dock space to catch buckets of panfish, some not more than a couple inches long, I say nothing until they feel free to jump on the deck on my moored boat to do what ever.
Again the biggest reasons Rick posted above is what are keeping people from coming up to your fine country.
