For the record it wasn't your comments I was referring to.
Also for the record I haven't yet decided which way I'm going to go when the time comes (and for my wife's bike it wasn't even on the radar), however before replying here I did a metric crap ton of reading on the issue (for a few weeks on and off, actually) bolstered by my experience with the trailer tire situation.
I'm an open minded person that investigates things sometimes relentlessly before making a decision. The evidence to backup many of the arguments *against* dark side is slim, if not none, despite the fact many like to tirelessly repeat them, and I never "drink the cool aid" just because it's the way most people lean, I use critical thinking and evidence to form a decision or opinion accordingly. I'm at that stage right now and still contemplating things, looking for evidence to or against (not just opinion) as well as trying to narrow down the exact legallity.
I respect the potential legal implications should the matter not be 100% clear, and would be the first to say the same thing to anyone else here, so I'm listening, and expected such.
That said, a charge being laid that may (or may likely not) stick is of zero evidence to me with regards to the safety aspect, however the many millions of Kilometers people have traveled on dark side spanning several decades is. An overzealous LEO could pull over my horse trailer and charge me for having LT tires fit to it, by that neither automatically makes my vehicle inherently dangerous, nor is it going to stick in courts as I *would* fight it tooth and nail, and there is plenty of evidence to support my side of the case. Therefore, it is unfair to compare that situation that would result in a charge to darkside and drawing any sort of correlations.
So, here's what I think I'm going to do - with an open mind, I'm going to draft a letter to the Minister of Transport as well as perhaps the head of the OPP, present the situation and evidence both to and against the matter, point out the unclear/fuzzy laws, and ask for their "official" word on the matter. From what I can see, despite much unnecessary fighting and uninformed (on both sides, admittedly) wrangling (this thread being a great example), nobody has ever actually contacted the government in a very formal way like this and asked for clarification. I'll be happy to do so.
