Well, I was hedging my bets with "some"... I am thinking it would end up being more than "none", but definitely not comprehensive.I'm not so convinced that will happen in such a smart way. Some single lines in good fishing spots will get replaced with double. Most won't be changed imo.
This really is truly useless though. Like a cop still has to witness this either way, and if they didn't feel they could make an improper passing charge stick there's already a bunch of other sufficiently vague charges they could bring out. This is classic Ontario attempting to legislate "crime" out of existence
