Over the years we’ve worked in many ways to encourage better land stewardship on both public and private lands in our area. We’ve funded research about optimal approaches to stewardship, and we’ve sponsored projects which help demonstrate responsible and sustainable land management.

Uxbridge Township has more than 30 aggregate pits in various stages of mining. We’d like to see aggregate pit rehabilitation occur in a way that is in tune with nature and the surrounding areas. See the location of licensed pits in this area: Ontario Aggregate Resources — Find a Pit and Quarry

Fifty million tons (or 2.5 million truckloads) of excavated material a year is created from large condo developments, subway and highway expansions in the GTA. Rural areas surrounding the GTA are increasingly becoming the place construction companies look for disposal sites. This excavated material may in some cases be contaminated. Most municipalities now have bylaws to oversee importation of fill. If you have concerns reach out to the local bylaw officer in your region.
