Mud Creek Ravine Restoration

Mud Creek reach one showing bank restoration and stabilization mesures which include the placement of field stones on the bank and the replanting of native grasses and shrubs.Urban Forestry is working in partnership with Toronto Water and the Toronto and Region Conservation Authority (TRCA) to improve storm water flow conditions and overall ravine health throughout the Mud Creek watershed. Mud Creek is part of the Don River Watershed and has been prioritized for management in both the TRCA Don River Watershed Plan and the Toronto Water Wet Weather Flow Master Plan. Urban Forestry is participating in various ways:

  • Ravine & Natural Feature Protection By-law review of construction plans
  • Identifying future stewardship initiatives and trail upgrades throughout the Belt Line
  • Phasing of invasive tree removal and replanting, as well as preventative tree management work to address flood conveyance issues


July 2016 Project Update

Project planning is underway for additional channel work in Reach 2, below Governor's Bridge, and Reach 6 above Heath Street Bridge to Moore Avenue. Construction for Reach 6 will begin in early summer 2016 and be completed in autumn 2016.  Trail closures will happen intermittently during this time.

This work will help improve storm water flows and ravine health, address public safety conditions and reduce erosion of public and private property.

Trail Closure:

Sections of the Beltline Trail will be closed during periods of active construction.  To protect your safety and the safety of the staff, please follow all posted construction signs and stay clear of the work area and equipment.  Your cooperation and patience is appreciated.

Tree Removal and Replacement: 

Trees will be removed to allow for access and construction as part of this necessary work.  As part of the forest management plan, an extensive restoration plan will incorporate plantings of new native trees and shrubs following construction by autumn 2016.  

For more information about the Mud Creek Project, please call TRCA Office at (416) 392-9720.


The Mud Creek watershed extends south from Moore Avenue to just south of the Evergreen Brick Works. mud creek and surounding neighbourhoodThe channel is located in Moore Park Ravine. Blockages during flood events have impacted tree health in the lower channel throughout the watershed from both accumulation of silt on top of tree roots and soil erosion causing tree root exposure and in some cases tree failure. The existing tree cover is dominated by invasive tree species including Norway maple and Manitoba maple. This dense canopy intensifies the erosion issues in this area by inhibiting vegetation growth. Retention of the full tree canopy will impact the success of the channel erosion projects by inhibiting the success of replanting efforts. Urban Forestry will be carefully examining the existing tree cover in each channel section to plan additional tree thinning phased over subsequent years to allow gradual replacement with native species.

New plantings in these restoration areas will take some time to establish and are extremely sensitive to trampling. Please help the success of this project by staying on trails, respecting signage and fencing and keeping your dog on-leash.

The first portion of the watercourse was reconstructed in 2012, located just north-west of the Evergreen Brick Works. This section is approximately 145 metres long and was experiencing severe bank erosion and flooding.

This view from north end of channel looking south shows dense canopy and bare soil conditions on surrounding forest slopes. Several larger invasive trees were removed from the mid-lower channel in 2012 and all of the smaller saplings were removed in early winter 2013. Additional removals will be phased over the next few years to allow gradual replacement with native species.

The view after channel rehabilitation and replanting fall 2012 from north end of channel looking south. Stream banks and gaps on slopes were planted with over 200 native trees, 1600 shrubs and 2000 live stakes to increase bank stability.

Reach 2 is located south of the Governor's bridge.

Brush accumulation at culvert can be seen. Slope instability and erosion from channel blockages have caused tree failure and bare slope conditions.  Invasive trees will be removed over time to allow replacement with native species. The southern portion of the channel will be planted in fall 2015 and additional planting will follow in 2016 following phase 2 of the northern channel works

Phase 1 of this channel reconstruction was completed in 2013.  The final reconstruction phase of the lower portion of the channel was completed in summer 2015.

Urban Forestry is now initiating the restoration phase of the lower portion of the channel fall 2015 that includes removal of invasive trees and replanting with native species. 


Reach 6 is located south of Moore Avenue and extends south to the Heath Street bridge.  Uncontrolled stormwater has caused site erosion and slope instablility. Urban Forestry will be reviewing the plans to address invasive trees and to develop a restoration plan. The channel design process is currently underway to initiate work in 2016.
