Saint-Hyacinthe offers medium and large commercial spaces on either side of Highway 20.
A number of car dealerships and a Rona Le Régional renovation centre are located on the south side of the highway. The north side has a Canadian Tire, Bureau en gros, Yellow, Harley Davidson, Club Piscine, Walmart and other stores.
The establishment of these businesses has helped stop the shopping migration and attracts regional clients to the Maskoutan territory, to the benefit of local businesses
