KWtoxman; you are correct the wording is vague, as is the wording of about 98% of the HTA and other legislation including the Criminal Code of Canada. It was written purposely vague, in an attempt to cover as many possible scenarios. If it was written with specifications etc then the CCofC would be well over 2,000 pages and the HTA would be numbered in the volumes.
Just because the wording is vague doesn't mean YOUR interpretation is the correct one, nor does it mean the cop on the street has the correct interpretation either. The ONLY interpretation which counts is that of the JP or judge. period.
Personally I could care less if someone wants to modify their bike and use integrated lights, not my butt on the line when they can be seen, (and will likely come on this forum to complain how some cager pulled out in front of them or rear ended them, while forgetting they bought a $50 piece of Chinese junk to replace the bright stock lights)..lol
BUT if a rider chooses to modify their bike then they NEED to be aware it "can" attract unwanted attention to them and result in an interaction with police, when otherwise none would have been unwarranted. That is what the OP was asking, and the simple answer is yes to both his questions. 1. Can it result in him being pulled over merely for that, and 2. Can it result in a ticket or "another ticket" in the case of a traffic stop for another offence.
Does it really matter what justification the officer uses for the ticket? No it still results in the same consequences...
Time and effort to attend court, (if he returned t to stock and had photos may get tossed by crown)
Possibly a few appearances in the event a trial is scheduled
Potential conviction
Potential insurance ramifications, (depending upon his insurers rating policies and how they deal with "equipment infractions")
