Looks like you're already to step B. We're still at step A here in
Quebec where they passed the laws. Still doesn't seem that they're
being enforced yet. We have recently seen a minimum passing law enacted
and an increase in fines for dooring. But:

I contacted the mayor to ask why the police would have the latitude to
not issue a ticket in this case and the police responded that their
officers always have the discretion as to when to issue citations.
With the no-fault insurance here, in the absence of a citation the
victim will have to go to small claims court and fight over this rather
than having the damages automatically covered by insurance.
People are complaining so we'll see what happens. The good thing here
is we have a lot of voters that ride bikes.
