All these "authority" types try to get you to comply with something so that they then have power over you. If you change your ride to comply with something and actually register it as such, then YES, they have authority over you. The law only has authority over things it regulates and governs. If it doesnt regulate something, then it has NO authority, further, if the law has no authority, then a LEO (law enforcement officer) cannot claim authority over you and your ride from a non-existant law. Ex, the law doesnt regulate the length of you fingernails, and therefore has no authority, meaning a cop cant charge you for having too long or short fingernails. The Canadian Constitution/ the Charter/ and the Provincial Offences Act explisitly state that if an officer is NOT acting according to the law and from authorisation granted to them by the law, they are to be treated as any other person. If a cop (constable on patrol) is not acting under any known real law, then they have no real power. Further, if a cop is trying to enforce non existant real laws, they themselves might actually be in violation of other laws and may face charges. You cannot violate the law to try to enforce non existant laws (meaning a cops opinion). Cops often say "cops are imune from civil and criminal persecution". Not true, as a cop, they have LIMITED imunity from persecution. But as a person who is in the employ of being a cop, they are wide open to being charged and sued. I hear all the time about cops under investigation, being charged, convicted, and sucessfully sued. Dont let them intimidate you.
Take a gander

Now specifically thats not true, the cop wasnt charged, but the PERSON acting as a cop was charged. The law clearly states that if an officer is not acting in accordance of the law, they are to be treated just like every other person. So if a cop does a royal screw up, the person they are (not the cop they are) can get nailed.
Another Officer faces drunk driving charges Officer faces drunk driving charges Again, not really the officer, but rather the PERSON is charged, because they arnt acting as a bonafied cop at the time.

A biggie TheStar.com | GTA | OPP officer charged with breach of trust OPP officer charged with breach of trust Again, the PERSON, not hte COP was charged. Night and day differnece, cop's on duty but not acting under any known authority, therefore the charges.

In Ontario, provincial, municipal, and city cops (but not RCMP) are governed by the POLICE SERVICES ACT. Read it. RCMP are governed by the R.C.M.P. ACT.

Just a quick lil crash course on common missused words being posted and their correct usage

1. Legal, this means its perfectly OK, means that the law has written something about it and says its ok.
2. Not Legal. Means that there is absoloutly nothing written about it, and therefore not governed or regulated. The length of your fingernail (whatever they are) are NOT LEGAL, because there is no law written for or agaist the length of nails.
3. Illegal, means something is written about it and that says charges are available under the Act/Statute/Code to be layed. Does NOT mean STRICTLY FORBIDDEN
4. Non-Legal means nothing is available, means unregulated, ungoverned.
