Vague Act in Ontario Pit bull Law confusing...

It's recently come to my attention that muzzling your Pit bull in your vehicle is complying with the Law. Since I've never heard of this before, nor many others, I decided to call London's Animal Care today to see what they had to say about it. I was sure it was some rediculas rumour going around, but I was told it was a specific violation of the act as the act specifys the conditions of private property as your back yard with the appropriate fencing, etc. It does not state that your vehicle in the act.
Right afterwards, I phoned the London Police department and asked the same question. Their response was quite opposite as they assured me there was no law about that. She even went another step further to have it checked out and came back with the same answer.
But I have heard via a forum where someone was pulled over, although not sure where in Ontario this happened and the police gave this man a warning. This goes to show you how vague this new law really is. It could differ from city to city. If this is the case, should you have to phone all the police departments within your route to see which departments allow or don't allow your dog to be muzzled while in the safe confines of your vehicle?
Matter of fact, I recall hearing that the temporary muzzles put out where for such reason. You muzzle your dog to get them from your home into your vehicle and remove the muzzle as prolonged use is unhealthy to the breathing of the dog. Twenty minutes is tops for the use of the tempory muzzles.
It seems that if it isn't specified in the law, then it is a violation according to AC.
Law abiding citizens of Pit bulls are learning something new as we go along. I would think they should give us a handbook, because it seems to change at their convience. How will we ever understand the law if it isn't in black and white and written down? How many other Ontarian's have never heard of this neither and driving around believing they are justly following the law? Further more, what other surprises will be find out in the future?
