Our Experience


We have over 200 public and private clients throughout Ontario. We have been working with Ontario Ministry of Environment for many years, and specialize in Environmental Activity and Sector Registry (EASRs) and Environmental Compliance Approvals (ECAs) for Air & Noise emissions, from Manufacturing, Waste Transfer Stations, and Municipal Water and Wastewater Facilities. 

More on Our Experience

Ontario’s Environmental Activity and Sector Registry (EASR)


If your facility meets the EASR criteria, we can register your operation with Ontario Ministry of the Environment. EASR operations include: paint spray booths, printing shops, non-hazardous waste transportation, small ground-mounted solar facilities, and facilities processing end-of-life vehicles.

Ontario’s Environmental Compliance Approvals (ECA)


Businesses with complex or unique types of operations, such as manufacturing facilities, landfill sites, water & wastewater treatment, and complex operations must apply for an ECA. The ECA application includes: Application form, Facility details, Emission Summary and Dispersion Modelling Report (ESDM), and noise screenings.

Environmental Reporting


ChemTRAC is a City of Toronto Municipal Bylaw that requires all facilities to annually track and report on their use of priority substances. The National Pollutant Release Inventory (NPRI) is Canada’s legislated, publicly accessible inventory of pollutant releases for reducing releases of toxic substances in the environment.

Biosolids Management


Biosolids are organic materials produced during wastewater treatment which may be added to soil to supply nutrients and replenish soil organic matter. Biosolids can be used on agricultural land, forests, rangelands, or on disturbed land in need of reclamation.

Environmental Assessments


Ontario's Environmental Assessment Act sets out a planning and decision making process so that environmental effects are considered before a project begins. A class environmental assessment sets out a streamlined self-assessment process. This applies to routine projects that have predictable and manageable environmental effects.

Ontario Ministry of Environment, Conservation and Parks

We have an excellent relationship with Ontario Ministry of Environment, as we work with them to meet all of their requirements and obtain your approvals. We go beyond just the bare minimum to satisfy all requirements to bring your facility into compliance at the lowest cost possible. 

More About Ontario's Environmental Approvals Process

Any Ontario business must have an environmental approval from the Ministry of the Environment, if it releases pollutants into the air, land or water, stores, transports or disposes of waste. Depending on the nature of the business activities, the owner must apply or register for either an Environmental Compliance Approval (ECA)which covers emissions and discharges related to air, noise, waste or sewage; or an Environmental Activity and Sector Registry (EASR), which is a registry is for business activities that pose minimal risk to the environment and human health, and are already regulated by other regulations; or a Renewable Energy Approval, which is needed for most solar, wind or bio-energy projects.  Businesses with complex or unique types of operations, such as landfill sites or wastewater treatment plants, must apply for an ECA. By law, your business must meet the specific conditions set out in the ECA.  To apply for an Environmental Compliance Approval (ECA) you need to complete the ECA application form, include copies of site drawings and all required supporting documents including facility and process details, site drawings, and emission emission dispersion modelling.  For waste disposal sites, a copy should be sent to  the Clerk’s office of the local municipality (both upper and lower tier) in which the facility/proposed facility is located.  Activities eligible for the EASR include automotive refinishing facilities, commercial printing facilities (lithographic, screen and digital), non-hazardous waste transportation systems (e.g. trucks and other motor vehicles, including vans and cars on public roads), small ground-mounted solar facilities, facilities processing end-of-life vehicles, and  specific construction-related water-taking activities. 


Acoustical Assessment Reports (AAR)

As a part of the Environmental Approvals, a facility's noise emissions must also be considered. A facility may be "screened out" based on the Ministry's noise screening method. If a facility does not meet the noise screening criterion, an AAR must be completed. An AAR calculates the facility's overall generated noise levels and compares it to the Environmental Noise Guidelines. The AAR projects the expected noise level from the facility at the closest receptor, usually the closest residence to the facility. This noise level must be below the Noise Guidelines in order to issue an ECA for the facility. If the facility exceed the Noise Guidelines, we can propose solutions in order to bring the facility into compliance. This can include adding noise barriers, recalibrating the operation of the equipment, and adding noise control measures for the equipment.

What is Biosolids Land Application Inspection?

The final byproduct of wastewater treatment is an organic rich bacteria sludge called biosolids. Under certain conditions these biosolids may be applied to agricultural land to help crop growth. The conditions under which the biosolids can be applied to land is detailed in the Certificate issued by Ontario Ministry of Environment for each specific site. These conditions include setbacks from ravines, property lines, slopes, roadways, etc. in order to ensure that adjacent sites are not contaminated. Biosolids land application inspections ensure that the spreaders adhere to these conditions. This is all documented in a daily site inspection for each day that the biosolids are being applied on land.
