(b) a mirror or mirrors securely attached to the vehicle and placed in such a position as to afford the driver a clearly reflected view of the roadway in the rear, or of any vehicle approaching from the rear. R.S.O. 1990, c. H.8, s. 66 (1).
Now, define "clearly" as used in the above clause.
If you have a mirror arrangement that is substandard per MVSA and you get a ticket on the grounds that the undersized mirror does not "clearly" provide a reflected view, it will be difficult to defend. If you have a mirror arrangement that meets MVSA then firstly, you are unlikely to get a ticket in the first place and secondly, if you do get a ticket, you have the defense that it meets MVSA.
Probability of enforcement of this type of thing, assuming you have at least one thing on the bike that you can point to and call it the "mirror", is pretty much nil.
