steve woods started this petition to Ministry of the Environment and

Prevent environmental damage to our neighbourhood from >200 heavy trucks per day transporting waste in and out of West Hill 24/7/365, resulting in the production of significant noxious gas emissions and raising neighbourhood noise/safety concerns.

West Hill, Coronation, Highland Creek, Centennial and West Rouge Neighbours:

THE ISSUE:  A proposal by 2683517 Ontario Inc. has been received by the Ontario Ministry of the Environment to develop a private waste processing and transfer plant, with a biogas anaerobic digestion system, at 633 Coronation Drive (just up the street from the sewage treatment plant) on the Lake side of the site.

FACT: If this proposal to process huge amounts of putrescible wastes and truck the wet incoming materials and biosolids byproduct out through our neighbourhoods all day and night is approved we are facing a major disruption to the liveability, and safety of our communities

FACT: The proposed operation will involve 20 times as many trucks as the proposal that was turned down by the Biosolids Environmental Assessment (EA) for the Highland Creek Treatment Plant, and includes 2 anaerobic digesters, 11 natural gas boilers, one open air storage facility, and other waste processing and storage facilities. 

FACT: The City of Toronto currently collects 150,000 tonnes per year of residential and commercial green-bin organics which are processed at its Dufferin and Disco Road Plants. The Coronation Plant proposes to process up to 900,000 tonnes of wet rotting waste annually – 6 times as much as the entire City of Toronto.  

FACT: Both these City owned plants are surrounded by industrial areas with direct major road access to 400 series highways without going through residential neighbourhoods, which are at least 700m from the site. The proposed site at 633 Coronation is within 200m of residential homes, within 500m of parks and within 700m of schools. The 6 or 7 kilometre trip to the 401 (depending on the route ) by >200 trucks per day would pass hundreds of homes, several schools (primary, and secondary), the University, seniors living facilities, shopping malls, fire/police stations, and community centres.

FACT: The Proponent is planning to truck in putrescible waste (wet decomposing waste) that may include but not be limited to: rotting food, plant waste, animal waste and human waste, and then after processing on site, ship out the residual biosolids and non-processed materials for land application or dumping. There will be noise from the processing plant operating 24/7/365, from heavy trucks entering and leaving the site, and significant emissions and odours from the plant and the trucks (they are typically the large dump trucks with the tarp covering – ie: open to air) loaded with putrescible wastes. Not only will the impact be to the immediate area (within a few km of this site) but along the route to the 401 (Beechgrove/Port Union or Manse/Morningside likely) with open top trucks causing excessive noise, odour, vehicle GHG emissions and emissions/odours from rotting wet cargo. The current number of trucks using either Beechgrove or Manse to get to 401 from Coronation Dr daily is less than 100, this proposal will at least triple the amount of trucks using these routes.

FACT: The recently rejected proposal to truck biosolids from the Highland Creek Sewage Treatment Plant (HCTP) involved an estimated 5 heavy trucks per day, 5 days per week. The Coronation proposal is planning 70 heavy trucks incoming with wet putrescibles (and likely leaving empty), and 30 heavy trucks leaving with biosolids digester residues (arriving empty). There will also be an unknown number of trucks removing unusable material to local city owned landfill sites. At least 200 heavy trucks (the two pictures above are examples of the type used in other such facilities) arriving or leaving the site every day of the year, 24 hours a day. The estimated greenhouse gases alone from heavy truck emissions will be about 10,000 tonnes of greenhouse gases (mainly carbon dioxide) – this is assuming only an 80km trip per truck (typically from small communities and to farmland), however the proposal states it can ship waste from anywhere in Ontario, and if 6 times the amount of waste from Toronto is expected every year the incoming truck routes will have to reach far beyond the outskirts of GTA, and significantly add to the greenhouse gas emissions.

FACT: The proposal confirms that 6 gases, which will severely affect the air quality, are to be emitted to the local environment from this processing system, The HCTP EA evaluated over 25 noxious gases; there are concerns that some noxious gases may have been missed in this assessment.  A December 2019 emission model released for the proposed plant showed the following emission estimates:

  •   nitrogen oxides (NOx)             - up to 35% of ministry limit
  •   sulphur dioxide (SO2)             - up to 69% of ministry limit
  •   particulate matter (PM)           - up to 21% of ministry limit
  •   carbon dioxide (CO2)            - up to 301% of ministry limit
  •   methane (CH4)                       - up to 40% of ministry limit
  •   total reduced sulfur (TRS)      - up to 71% of ministry limit

It should also be noted that besides the emissions that far exceed the allowable limit, all 6 of these pollutant emission rates are considered 'significant' according to ministry guidelines. 

The above emission rate is based on processing 1240 tonnes of wet waste per day, but a site approval was granted in early 2019 to increase importing of up to 2500 tonnes (about double what is being presented for assessment) daily. It is unclear if these emission amounts should be doubled, essentially making many of the acknowledged noxious gases well above the legal limit. The impact from increased trucking, air quality, noise, safety etc are all likely impacted significantly as well.

FACT: In March, a brief notice outlining this huge project was sent to only a few residents immediately adjacent to the project site. However, the significant environmental impacts of this project will be felt by residents all the way to the 401. Because of COVID-19 we have all been self-isolating for the last two months. This has hindered the residents from hearing about, and learning details about this project (a copy of the text of the notice is included at the end of this petition).

FACT: The current deadline for submission of comments to the Client Services and Submissions Branch at the Ministry of the Environment is May 24th. (The deadline has just been extended 30 days to June 23rd). Thanks to all involved for making this happen.

Therefore, we the undersigned, urge the Ministry of the Environment to:

  1.  Reject the application and recommend that it be relocated to another site which is in a more suitable location (similar to the two City processing plants) or a rural location closer to source/destination material and away from residential areas and close to the 401, or
  2. Extend the deadline for submission of comments for two months to August 24, 2020, and
  3. Hold a public meeting to allow the proponent to fully explain the details of this significant proposal to the local communities that will be impacted, and
  4. Request that the City of Toronto Public Health Department conduct a study of the health impacts of this proposal on the affected communities, and City of Toronto Traffic Management do a detailed study to assess the impact of the significant additional heavy truck traffic in residential neighbourhoods.

What are we asking you to do (as many of the items listed below as possible):

1. – Review the two ERO (Environmental Registry of Ontario) links below and submit your comments for both based on some of the information above, or your own thoughts/concerns.

                                      Environmental Registry #1

                                      Environmental Registry #2

2. – Write a letter expressing your concerns to the Ontario Minister of the Environment, Conservation and Parks (Jeff Yurek)

3. – Write a letter expressing your concerns to our MPP (Vijay Thanigasalam)

4. – Write a letter expressing your concerns our Councillor (Jennifer McKelvie), and request that Toronto Public Health (TPH) prepare a formal HIA (Health impact assessment) for the project including the additional proposed truck traffic, and Toronto Traffic Management be asked to review the Traffic impact of this proposal.

5 – Tell your friends/neighbours/newspapers etc.

6 – Sign this petition, and add a comment (it is so much more valuable if you do).

Thanks neighbours – if you require additional information regarding this or any other community issues please contact the email address below.                                                            


Below is copy of text of letter initially sent to property owners and tenants within 300m, and later revised to 500m of the proposal site.


Notice to all adjacent property owners and tenants:

2683517 Ontario Inc. proposes to construct an organics processing centre (OPC) and anaerobic digester (AD) facility at 633 Coronation Drive, Scarborough, Ontario.

The OPC will process industrial commercial and institutional (IC&I) and source separated organics (SSO) for use as in the anaerobic digester system and for export from the facility for use at other appropriate locations. All material brought to the facility will be received, off-loaded and processed within the enclosed OPC.

The AD facility will process organics from the OPC to generate biogas and organic fertilizer called digestate.  The biogas will be cleaned to produce renewable natural gas for injection into the existing natural gas grid. The digestate will be exported from the facility for use on area farms as an organic fertilizer.

2683517 Ontario Inc. has applied for an Environmental Compliance Approval from the Ministry of Environment Conservation and Parks to process a maximum of 1,240 tonnes/day of material (452,600 tonnes/year). This material will be either comprised of up to 1,240 tonnes of non-hazardous waste or up to 1,240 cubic metres of other liquid (non-hazardous) waste per day.

The service area for the facility is the province of Ontario. The facility will operate continuously, 24 hours per day, 365 days per year. The facility shares the site with an existing permitted waste disposal facility (ECA Permit 4568-AJTR84) which processes construction and demolition (C&D) material.

All of these feedstocks will be received and processed inside the OPC to manage and treat odours associated with the reception of these products; all air within the OPC is treated prior to reuse within the building and/or discharge to the environment. Up to 219,000 tonnes per year (620 tonnes/day) of organics from the OPC will be processed on-site in the AD facility, the remainder will be exported from the facility for use at other appropriate locations.

IF there is any concern or clarifications required, please send written comments to Part V Director, Waste Approvals, Environmental Approvals Branch, Ministry of the Environment Conservation and Parks, 135 St. Clair Avenue West, Floor 1, Toronto, Ontario, M4V 1P5 within 15 days of receipt of this Notice.
