Renewing Ontario license plate stickers just got harder

`There's the rub. My door sticker states 13000lbs/5897KG. When I trade in a couple years I wanted to consider another F350 dually or F450 but I guess the Ontario guberment does not want to promote safer large recreational vehicle towing as both the 2015 F350 and F450 are stickered at about 6300KG.
I would like to hear from a new F350 owners what his experience will be trying to get the exemption.
I'll tell ya I smell a fight coming with a bureaucrat.
