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

Ontario's infrastructure relies on more material than most people realize. 📊
@_OSSGA reports that between 2026 and 2041, Ontario will need 4 billion tonnes of aggregate to support a growing population, housing, infrastructure, and construction. 🪨
Those figures reflect the ongoing need to maintain existing infrastructure while preparing for future growth. 🏗️
Understanding demand is one of the first steps toward planning responsibly. 🧭

Pits and quarries account for less than 2% of Ontario’s total permitted water taking. 💧@_OSSGA highlights this figure to provide broader context around industrial water use across the province. 📊 Aggregate operations operate within regulated permitting systems that include monitoring, reporting, and environmental review requirements. 📄 Understanding scale and context is important when discussing water use and infrastructure materials. 🧠 Provincial data helps separate assumptions from measurable resource management realities. 📚

P&Q caught up early this year with Sharon Armstrong at the Ontario Stone, Sand & Gravel Association (@_OSSGA) Operations, Health & Safety Seminar in Toronto.
Armstrong has been involved with the organization for more than a decade, having served as vice president of industry and stakeholder relations from 2015 to 2025. Armstrong took over late last year as OSSGA executive director.

Many aggregate reserves supplying the GTA were developed decades ago. @_OSSGA lets us know that more than two thirds of these reserves are over 35 years old! As reserves mature, planning for replacement supply becomes critical. We all must support continuity by planning supply transitions well in advance. Early action helps avoid gaps that could slow future projects. 🏗️ #OSSGA #SupplyPlanning #FutureBuilds #Infrastructure #PlanningForTheFuture

Some construction materials take over a decade to approve before they are used. OSSGA reports that approvals for new aggregate sites can take up to 12 years from start to finish! 📄 These timelines mean supply decisions must be made long before demand peaks. Early planning helps reduce future bottlenecks and project delays. @_OSSGA 🧭

A working aquaculture system helped bring this lake to life. 🐟 McMillan Farm in Puslinch began rehabilitation in 2002 and now includes a 65 acre lake within a nearly 100 acre restored property. 🌊 A floating raceway operated by Izumi Aquaculture reintroduced nutrients into water that was once too low in biological activity to support much life. ♻️ Today, birds, amphibians, turtles, plants, and native species are tracked through ecological surveys as biodiversity indicators. 🦆Swipe to see how aquaculture helped restart the ecosystem. 👆@IncIzumi

A single school requires thousands of tonnes of material before any walls go up. 🏫 GravelFacts.ca explains that an average school requires roughly 13,000 tonnes of aggregate to support foundations, concrete, and site infrastructure. 🧱That material is engineered to carry structural loads, manage drainage, and provide long term stability under constant use. 🏗️ Decisions made at the foundation stage affect maintenance, durability, and performance. Supplying consistent, high quality aggregate is how we support long-lasting community infrastructure. What is the nearest school to you? Let us know in the comments below. 🌱 #CBM #Community #Education #OSSGA #Schools @_OSSGA

For 70 years @_OSSGA and its members have been supplying the aggregate needed to build critical infrastructure in Ontario.
It was a pleasure to join their annual conference alongside @fordnation and their members to celebrate this milestone!

While the annual Operations, Health & Safety Seminar is the Ontario, Stone, Sand & Gravel Association’s (@_OSSGA) signature event, the organization representing Ontario’s aggregate producers has evolved its educational offerings beyond the seminar.
Julie Harrington, senior director of #training and events at OSSGA, shared more on the association’s programs during an exclusive P&Q interview at the seminar. ⬇️

The aggregate industry supports approximately 7,000 direct jobs and more than 34,000 indirect jobs across Ontario. These roles span production, transportation, engineering, and environmental oversight tied to infrastructure development. 👷♂️@_OSSGA reports that this activity contributes roughly 1.6 billion dollars annually to the provincial economy. Aggregate supply plays a direct role in supporting skilled work and economic stability in communities across Ontario. 📈

🚨@_OSSGA reports that more than two thirds of licensed reserves supplying the GTA are over 35 years old. 🛠️ Renewal and new approvals are essential to maintain a steady, responsible supply. 🌾 Planning now supports safe, affordable infrastructure in the years ahead. 🧮

Half of Ontario’s aggregate supply comes from the Greater Golden Horseshoe. 📊 According to @_OSSGA, this production fuels homes, highways, and transit for millions. 🚉Local output means communities can grow sustainably. 🌿 #Ontario #CommunityGrowth #SmartBuilding #CBM #OSSGA

Aggregates are heavy! ⚖️ @_OSSGA notes that transportation is the largest cost and emissions factor. Local supply reduces fuel use, lowers emissions, and makes projects more efficient. 🏛️ Supporting nearby sources supports sustainability. 🌐 #LocalSupply #Efficiency #Sustainability #CBM #OSSGA
