Why doesn't the Dundas East bike lane have bollards to prevent cars and trucks from entering it?

I'm tired of seeing trucks at the various car dealerships on this stretch using the bike lane as a loading dock. It's so prevalent it's been caught on google street view.

Why can't the City install bollards or narrow the lane with additional concrete barriers to prevent the trucks from using it? Seems like a simple fix since enforcement is next to nil and even then it's only a $200 ticket (parking in a bike lane). This is also a no stopping zone, so I'd love to see an additional ticket for $300 (parking, no stopping) issued as well.
