Heck of a stretch your trying to make...just because YOU can't afford the set user fee...it's not an obstruction as defined by the act. If the guy behind you is willing to 'pay to play' he can launch unobstructed.
The definition of 'obstruction' from the act:
Quote:
obstruction means any thing, including a vessel that is left anchored, moored or adrift or a wreck, that obstructs or impedes navigation or renders it more difficult or dangerous, but does not include a thing of natural origin unless a person causes the thing of natural origin to obstruct or impede navigation or to render it more difficult or dangerous.
Every municipality in Ontario has the right to charge or not charge a user fee. Looks like yours doesn't...but from what I have read on here there are some that do.
