The following list is provided for information purposes, to help you make more enlightened choices. Don't forget: you must apply for authorization from Québec's Ministère de la Culture et des Communications as well as permits from the City of Montréal. You must then wait for the authorization and permits before purchasing your materials or beginning work.
