It is gravy and curd cheese over fries.
Smokey, Poutine is dish in the same way a sandwich is a dish. You would no more order a sandwich as have them ask "do you want the bread" than asking for a poutine and having them ask if you want fries. Poutine is the dish, not the dressing.
Something more like that... the grated cheese thing isn't very common at all.
