Saw this article today about the province thinking of banning new bike lanes that reduce the number car lanes. Not sure how likely it is to become law or how much it would affect the plans mentioned above.

I didn't see anything the last time I was that way a few weeks ago. But then again I didn't realize they were adding a stair there. Is it supposed to be on north or south side of Dundas? I'll have a look the next time I go by.
