Poutine probably did originate as a French-Canadian specialty, but it has traveled eastward.
Poutine is most often hot FFs and fresh white cheese curds topped with brown gravy. They can also be topped with red sauce (marinara or other varietal sauce) and cheese of choice for Italienne-style; Mexican-style with cheese, jalapeños and salsa (think nachos); or any other topping or combination of toppings. The only requisite seems to be cheese in some form. In and around Montreal, they're even served at Burger King. That said, it becomes apparent that the final quality depends upon the individual ingredients. As for the potatoes, the better places go through the two-step oil-blanching, then golden-frying to achieve the crisp exterior-creamy interior. The toppings can range from bottled to housemade-with-care varieties. "Brown sauce" for poutine is available as a standard condiment at groceries. I've included a few places offering poutine for location and variation purposes; of particular interest are Bud the Spud in Halifax (two years ago) and Fameux Viande Fumée et Charcuterie and Ma-Am-M Bolduc! In Montreal (1 and 2 years ago respectively).
