Rosenberg Building Supply Inc — Building Materials & Supply in Thessalon, ON
Rosenberg Building Supply has been serving contractors and homeowners along Highway 17 in northern Ontario since the 1950s, when it started as a sawmill making railway ties for CP Rail. Located at 15345 Highway 17 in Thessalon, the yard has grown into a full building supply operation that stocks the materials needed for most renovation and construction projects without requiring a four-hour drive south to a big-box centre. Phone: 705-842-2303.
Distance is the real variable in northern Ontario renovation planning. Contractors in Thessalon and the Algoma District can’t count on same-day deliveries from Sudbury or Sault Ste. Marie when a project runs short on framing lumber or roofing shingles. Having a local yard that stocks a full range reduces that risk and the scheduling delays that come with it. Rosenberg has operated on that premise for over 70 years, surviving multiple ownership changes while maintaining the same core function: a stocked, accessible supply point for the communities that line Highway 17 through the Algoma District.
