The only other pertinent example that I could cite for you, and it is one that is.... Zip lines are an occasional thing that pop up. What we do find quite often on smaller waterways—and there are two or three that I passed driving between our head office in Peterborough and here—is where cables have been strung across the rivers. Going back to the fencing issue, fences are built right through the waterway. If you don't know they're there, they can be a public safety hazard if you're on that particular waterway.
It also goes to the restricted access and the public's right to access. The riparian rights of that particular waterway are not owned by that particular land owner, but they seek to cordon off that particular waterway. They may own the land on both sides of the river, but they don't own the bed of the river, the water itself, or the navigation rights on it. When putting up those fences, which is a very common occurrence in some places more than others, but it happens quite frequently, not only is it a public safety issue, but it's an access issue. That would be the most common example I could cite for you.
