Avoiding Ontario Place P-gates
It's possible to follow the "old" route to the south instead of taking the current path with its P-gates. A few barriers that were in place at the west end on Wednesday morning were gone by Wednesday evening. Currently, the only obstacle of note is the gate at the east end on the roadway, which may or may not be closed, but that's trivial to get around.
During the weekday, all you see is hectares of empty pavement and concrete, no P-gates, and no traffic signals. In fact, it may even be quicker to ride that way if the alternative is hitting a red or two on the current routing.

P gates are the subject of today's The Fixer in the Toronto Star. Here is the article:
Interestingly that first the Ontario Place person says that the problem is cars using the path:
And this is very, very bad. But the solution to this problem is slowing down bicyclists:
Anyone want to call Daley and ask, is the problem really cars on the path, or is it that bicycles head through the intersections too fast? Because drivers, you know, don't notice the signalized bicycle crossing. And slow bicycles may be able to stop when a car comes barreling through.
By the way, slowing down trail users will just make a bigger mess. Ontario Place wants to try that, I might decide to stop, dismount my bike, and slowly (and safely!) walk across the road accesses....preferably when an event is on.
Is this really something to even complain about?
Just slow down for 10 bloody seconds and pass the barriers with care.
Considering these p-gates keep cars OFF of the route, it's probably something we don't need to throw our arms up over.
Its not the tour de france. You're out there getting to work, or going to a friend's, getting exercise, contributing to helping the planet... you don't need to do all that at a non-stop rate of 35km/h.
There are zippo cars in the Ontario Place parking lot on a weekday morning or evening. What are the odds that one of those non-existent cars will want to drive down the trail? Likewise zippo. Yet the P-gates are closed, dispite the utter lack of events or attendance at Ontario Place.
I think that the "keep the cars off the trail" is BS spin. I expect that Ontario Place's logic goes like this:
I'll also point out that, despite the long design process involved in relocating the trail, the intersections are poorly-designed and unsafe even wthout the P-gates.
Do traffic engineers try to improve the safety of dangerous intersections by narrowing them down with metal barriers in the travel lanes to make a narrow gap through the intersection? This would surely slow the cars down and increase their safety, no?
If I was the only one on the trail I wouldn't care as much. When it gets busy, you'll get strollers, joggers, rollerbladers, and cyclists all making random moves to squeeze through. "Just slow down" is not the answer to this problem.
