Makes sense because the punishment can't be consistent between charges.
For example:
Scenario 1:
I'm drunk in my canoe. I have an Ontario drivers license, so I am charged under the H.T.A., I receive demerit points AND a license suspension - along with a hefty fine and possibly impound my vehicle.
Scenario 2:
I'm drunk in my canoe. I DO NOT have an Ontario drivers license (or any license fo that matter). I can be charged, but the punishment isn't the same. I do not have a vehicle to be impounded, I won't get any demerit points nor will my license be suspended (because I don't have a license) so really - all I will get is a fine.
The fact that all cases can't be punished the same implies (and is fact) that some people are punished much much harder than others, for the EXACT same offense - which isn't consistent with the Canadian Charter of Rights and Freedoms.
I'm glad this will be lifted, not so I can get hammered in my canoe, but for the overall fairness to anyone in this situation.
Crack a beer and get paddling! (or not)
