I also live in Ontario, and you are confusing the Yellow sticker requirement with the licence. There is an RV Guide at the MTO site that explains all this.
Following is a small quote:
A truck only:
Class "G" if the truck is registered for and weighs 11,000 kgs (24,250 lbs) or less, or
Class "D" if the truck is registered for or weighs more than 11,000 kgs.
A truck towing a trailer and/or a motor vehicle:
Class "G" if the truck is registered for and the combination weighs 11,000 kgs (24,250 lbs) or less,
Class "D" if the truck is registered for or the combination weighs more than 11,000 kgs, or
Class "A" if the weight of the towed vehicle or the combined weight of the towed vehicles exceeds 4,600 kgs (10,141 lbs).
Yellow Sticker:
An annual safety inspection is required:
- on a truck, which does not tow a trailer if:
- the truck's actual weight, registered gross weight or gross vehicle weight rating exceeds 4,500 kgs (9,920 lbs).
- on a truck, which tows a house trailer only:
- if the truck's RGW exceeds 4,500 kgs.
- if the truck's gross vehicle weight rating exceeds 4,500 kgs, or
- if the truck's actual weight (without the house trailer attached), exceeds 4,500 kgs.
Notes:
- house trailer weight is not used when determining a truck's actual weight.
- house trailer weight is used to determine a truck's RGW.
- a house trailer does not require an annual safety inspection.
- on both the truck and towed trailer (other than a house trailer) if:
- the truck's actual weight, registered gross weight or gross vehicle weight rating exceeds 4,500 kgs, or
- the actual weight of the truck, when added to the actual weight of the towed trailer or trailers exceeds 4,500 kgs, or
- the gross vehicle weight rating of the truck, when added to the gross vehicle weight rating of the towed trailer or trailers exceeds 4,500 kgs.

Something else you could do is go back to the dealer where you want to buy the trailer and ask them if your require a Yellow Sticker for the trailer you want. They should be able to answer all your questions regarding this problem. I went through the same thing you are doing back in September only to discover that it didn't apply to me. If you don't register the trailer to its full GVWR then it doesn't apply. Are you really going to load your trailer right up to it's potential of 4600kg? If not, then register it at 4590 and save yourself the problem. The same thing for your truck. If it is registered for licence purposes as a non-commercial vehicle (You don't use it for business purposes other than commuting to work) then it also doesn't require the A licence. Check out the MTO site, as well and good luck.
