If you’re an Ontario resident, you can start the process to appeal this instrument decision.
First, you’ll need to seek leave (i.e. get permission) from the relevant appellate body to appeal the decision.
If the appellate body grants leave, the appeal itself will follow.
Seek leave to appeal
To seek leave to appeal, you need to do these three things:
- prepare your application
- provide notice to the minister
- mail your application to three parties

Original proposal
Proposal details
This proposal is for a new Environmental Compliance Approval (waste disposal site) for 101172801 Saskatchewan Ltd. (Trirock Construction Limited), the operator of the soil processing facility located at 5878 Highway 9 in Schomberg, New Tecumseth, County of Simcoe, Ontario.
The 3-hectare site will be used as a Class 1 Soil Management Site and resides within a 56.7 hectare works yard. The site will receive dry excess soils from Project sites in Ontario. The site has a maximum daily receiving rate of 580 cubic meters of soils (995 tonnes) and a maximum total storage capacity of 25,000 cubic meters of soil at any one time.
All incoming excess soils are tested to ensure the soil quality requirements are met for the soil processing facility. Accepted soils will be sorted using mechanical sieves in order to recover reusable soils for construction applications or similar. Once sorted and processed for re-use; the soil quality of the processed soil is tested prior to any outbound soil shipment. This sorting process will include some aggregate materials. Residual excess soils which do not have a commercial re-use are to be transported to a permitted off-site treatment or disposal facility.
Receiving, processing, and shipping activities may take place between 6:00 a.m. to 7:00 p.m., Monday to Friday and 7:00 a.m. to 5:00 p.m. on Saturday. The site occasionally provides services outside of the typical operating hours for emergency situations or short-term contract requirements (e.g., after hours and weekends).
