The Mohawk established a network for communications among the Mohawk villages/reserves of Akwesasne, Kanesatake and Kahnawake, using hand-held radios, cellular phones, air raid sirens and fire hall bells, as well as local radio stations, and human patrols. The situation escalated as the local Mohawk were joined by Natives from across Canada and the United States. Despite pressure to do so, their barricade was not dismantled. The SQ established their own blockades on Highway 344 to restrict access to Oka and Kanesatake. Another group of Mohawk at the nearby reserve of Kahnawake, in solidarity with Kanesatake, blockaded the Mercier Bridge at the point where it passed through their territory, thereby sealing off a major access point between the Island of Montreal and Montreal's densely populated South Shore suburbs.
