Freshmart
L'Intermarché
Loblaws / Loblaw GreatFood / Loblaws CityMarket
Lucky Dollar Foods
Maxi / Maxi & Cie
NG Cash & Carry

T & T Supermarket
Valu-mart
Wholesale Club / Club Entrepôt
Your Independent Grocer / Independent CityMarket

Yes there are other big oligopoly chains like metro, Sobeys/Safeway, Pattison, but I think it's best to start with one major chain to see how much coordinated action can affect them.
