From concrete channel to living creek

For decades, the creek has run through Jefferson, Jordan and Jayfield Parks inside a straight, poured-concrete channel. Channels like this were common across Ontario in the 1960s and 70s, built to move stormwater away from new subdivisions as quickly as possible.

That speed came at a cost. Concrete banks leave no room for fish habitat, no soil or roots to filter runoff before it reaches the creek, and no floodplain to slow the water during a storm. Over time, the aging concrete lining has also begun to crack, raising maintenance costs for the city. Where the concrete ends, the exposed banks erode just as easily, washing sediment straight into the creek.

The proposal is for the City of Brampton and TRCA to remove the concrete lining where feasible and rebuild the creek with natural curves, a floodplain, and banks held together by living roots instead of poured slab.

Banks would be reshaped to gentler slopes where appropriate, and erosion-control and bioengineering measures, such as geotextile, riprap and native seeding and planting, would be applied based on technical recommendations. The anticipated result: slower water, more habitat, and far less long-term maintenance.

Here is how each problem from the trail entry sign would be addressed:

A concrete channel supports almost nothing. On the morning of 13 September 2026 we walked all three parks before any restoration work began: 22 bird species and 213 detections, mostly common urban birds, along a creek of shallow, murky water with no riffles or pools. In TRCA's watershed-wide survey, no fish were found at three of five monitoring stations along the creek.

Watch for Eastern Wood-Pewees hunting insects in the mature trees, Common Yellowthroats calling from the dense thickets, and Mallards resting beside the creek. Restoration is anticipated to bring more native species, including native fish such as creek chub and white sucker, and we will repeat the surveys to measure the change.

Every species along this corridor earns its place: trees give canopy and shade, shrubs and deep roots hold the bank together, and flowers and grasses feed pollinators and resist erosion. None of them are decorative choices. They're also the first line of defence against invasive species, which would otherwise crowd them out.

Each was chosen to suit the wet, moist or drier conditions of its planting zone along the creek corridor.

Removing concrete and planting native species is the hard part. Keeping this stretch healthy afterward is an ongoing job, one that works best with the people who use the park every day.

Tell us what you think, join a Community Bird Watch, or share a bird photo or sighting next time you're here. Every bit of feedback helps the City of Brampton and TRCA plan what comes next.

A few ways to help: stay on designated trails, respect wildlife and new plantings, avoid removing or damaging plants, keep litter and pollutants out, and observe without disturbing sensitive habitat. Recovery is expected to take a few years, not a few months, so newly planted areas will look young at first.
