#Ontario needs aggregate. But do we really need more new pits and quarries? Before approving more land for extraction, we should ask whether Ontario's existing #aggregate supply can meet our needs. Good planning starts with demonstrated need. www.reformgravelmining.ca/aggregate-su...

We recognize that respect for land and water is inseparable from Indigenous and Treaty rights. Our work takes place across Treaty and unceded lands. Today, we listen, learn and reflect on what reconciliation requires of us—including how we make decisions about land. reformgravelmining.ca/resources

Ontario needs aggregate. But do we need every new pit or quarry? Ontario's own study identified 6.2 billion tonnes of reserves in the Greater Golden Horseshoe — enough for decades at current consumption. Good planning starts with what we actually need. www.reformgravelmining.ca/aggregate-su...

The most important word in our name may be REFORM. RGMC isn't arguing that Ontario will never need aggregate. We're arguing that rules governing where, when & how extraction happens must protect water, health, farmland, climate & communities. We can do better www.reformgravelmining.ca/who-we-are
Reform, it's in our name

Land-use decisions aren't made on empty land. RGMC believes resource extraction reform must include meaningful consultation with Indigenous Nations & compensation that respects Treaty rights. Reconciliation has to be reflected in how decisions get made. reformgravelmining.ca/damn-campaign/
