I discovered this rather late, but would like to add my thoughts. He is certainly, a really lovely boy! He looks pretty well made all round.
Judging by his colour, bone, height etc., he quite well might be a full or cross Gypsy Horse. There are many in Canada and lots of breeders cross breed Gypsies to other drafts, to obtain Drum Horses. Looking at his feather (and it is feather in horses, not feathers) one and possibly both, had it in good quantity. Feather is recessive and most usually, breeding a feathered horse to a non-feathered or not very good feathered horse, will end up with a poorly feathered horse. His feather looks to be bog-burned across the front, which tells me that with good care, you should be able to grow it to the ground.
Very few drafts across the world, have what we would describe as good feather. The Gypsy Horse is one of those breeds, hence my thought he might be a Gypsy cross.
If you would give me permission, I could post his pic on the GH forum, to see if anyone recognises him. We do have many Canadian members. Let me know.
Another quick word. Do pay close attention to what might be going on under his feather, especially on the back of his pasterns. Almost all feathered breeds can get horrid problems there, (ie. scratches and CPL) if not constantly watched. Check all four feet weekly.
