The problem I have with the 'new' (Level 2) crossover signage in Ontario is the flashing beacons are off to the side rather than overhead in the driver's field of view where they are in the older 'Level 1' configuration. In some cases, because of curb design, trees, or whatever, they can be quite a bit off to the side to the point of being obscured. In a couple of communities that I know of in Central Ontario that originally had this design of crossover (in both cases a built-up area reduced speed zone interrupting a highway speed zone), they have been replaced with full signals.
In my opinion, if they repeated both the signs and lights overhead the lane it would be much safer.
