Take a guess: what percentage of Ontario's aggregate goes toward roads and highways? 🤔 @_OSSGA puts it at nearly 60%, including aggregate used in asphalt and concrete. 🛣️ That's a significant share of Ontario's stone, sand and gravel supporting the transportation network we use every day. 🪨 Would you have expected the number to be this high? 👇 #OntarioRoads #Aggregate #Infrastructure #Construction #CBM

Thank you for taking the time to meet with the team and see firsthand how Ontario’s aggregate industry supports road building and infrastructure projects across the province. We appreciated the chance to discuss the challenges and opportunities facing our industry.

🌊 More than 293 hectares of aquatic habitat — the equivalent of 1,849 NHL hockey rinks — have been created from rehabilitated aggregate sites in Ontario. That's real community impact. These rehabilitated sites provide valuable habitats and support biodiversity in the local areas long after extraction is complete. ✅ Learn more about the industry's progressive rehabilitation practices: ossga.com/gravel_facts/rehab…

♻️ An excellent day on the road with OSSGA members and industry partners during our Rehabilitation Tour, showcasing how former aggregate sites can be transformed into valuable community, environmental and economic assets. A highlight of the tour was a stop at the Royal Botanical Gardens’ Rock Garden, where we rededicated the OSSGA Bronze Plaque Award. Once a gravel pit, the Rock Garden stands today as one of Ontario's most celebrated examples of aggregate rehabilitation. Thank you to our participating members, sponsors and the @RBGCanada!

🌊 Did you know that 92 per cent of the water used to wash and process aggregate is recycled through a closed-loop system? It’s one of the ways aggregate producers responsibly manage resources while supplying the materials our communities need. 🔗 Learn more: ossga.com/gravel_facts/rehab…

What if yesterday's concrete could help build tomorrow's infrastructure? ♻️ Concrete that has reached the end of one use can still contain valuable aggregate. Suitable material can be recovered, processed and reused as recycled aggregate in new applications instead of being treated solely as waste. 🪨 That means a material that already helped build something once can potentially contribute again. It's resource efficiency on an infrastructure scale. 🏗️ @_OSSGA #SecondHandSeptember #RecycledAggregates #ResourceEfficiency #OntarioConstruction #CBM

As Canada navigates ongoing trade uncertainty, investing in homegrown infrastructure is essential to supporting jobs, economic growth and long-term competitiveness. Building Ontario means building a stronger, more resilient economy using local materials.
