Earlier quoted context omitted.
In Quebec French we use “toute garnie” to refer to a pizza with red sauce, mozzarella, mushrooms, green peppers and pepperonis.
Here in Ontario English we call that pizza deluxe!
I'm in Ontario but in a heavily French area (i.e., East of Ottawa) and "toute garni / all dressed" is common. You'll find it places like Ottawa as well given the proximity to Quebec and French population.
