Proposed Amendments to O. Reg. 153/04

As a result of the development of the provincial Excess Soil Management Policy, amendments have been proposed for O. Reg. 153/04 (Made under Part XV.1 of the Environmental Protection Act, R.S.O. 1990, c. E.19). The policy aims to dissolve any confusion or concerns surrounding the reuse of soil or fill materials originating from an excavation site. The framework for the policy, which includes a number of actions to be taken based on key goals and principles, was finalized in December 2016 following review of input from partner ministries and industry. The regulatory proposal is anticipated to be finalized before the close of 2017, with open commentary welcomed until June 23, 2017.

What changes are proposed for O. Reg. 153/04?

The following list presents a summary of the proposed amendments, with general comments from JFM Environmental Limited presented in blue italics:

  • Provisions related to bringing soil to an RSC property would be amended to align with the proposed Excess Soil Reuse Regulation.
  • Stockpile sampling requirements will be amended per the stockpile sampling requirements in the proposed Excess Soil Reuse Regulation.
  • A new requirement will be added to require sampling outside of APECs for industrial properties in a manner consistent with the proposed Excess Soil Reuse Regulation.
  • As part of having a risk assessment accepted for a property, the Director may provide relief from delineation requirements to applicable site condition standards based on the following specified conditions;
    • all contaminants of concern are identified;
    • maximum concentrations are identified for all contaminants of concern;
    • all reasonable efforts to delineate to the applicable site condition standards were undertaken;
    • the property is appropriately characterized;
    • additional delineation will not lead to an improved understanding of the distribution of contaminants; and,
    • there are practical or negative environmental reasons that are impediments to further delineation to the applicable site condition standards.
  • O. Reg. 153/04 would be amended such that, if a Qualified Person determines that an applicable site condition standard is exceeded at a property solely because a substance has been used for the purpose of traffic and pedestrian safety under conditions of snow/ice, the standard is deemed not to be exceeded.
    • This exemption previously only applied to contamination coming from deicing applications on roadways and highways, this update will extend the exemption to the use of deicing compounds on private properties. Examples of contaminants that this exemption could apply to include; sodium, sodium adsorption ratio, chloride, and electrical conductivity.

  • A provision would be added to the RSC regulation to exempt a change in the use of property where:Commercial property with the upper floors being used for residential purposes.
    • the change in property use is from commercial (other than a use described in clause (b) of subsection 32 (1) of O. Reg. 153/04) to residential
    • the change in property use is to take place within an existing building no greater than four storeys in height and will be limited to the portion of the building above the first storey above grade (i.e. the ground floor remains commercial);
    • the ground floor and any below grade structures are not being redeveloped or replaced, and the footprint of the building will remain the same after the change in property use.
    • This new exemption will allow applicable commercial properties to convert their upper floors to residential purposes without filing a Record of Site Condition.


      A Phase I ESA should be completed for due diligence as part of a property transaction.

  • It is proposed that O. Reg. 153/04 be amended such that an RSC would be required prior to converting the ground floor from commercial property use to residential of a building whose owner had earlier availed him or herself of the exemption outlined above, and prior to rebuilding a new mixed use building at such a property.
  • O. Reg. 153/04 would be amended such that the definition of “road” does not include a road temporarily constructed and that is recognized as temporary in a planning or development approval (i.e. the temporary road would retain the past use, similar to vacant land, until changed to another use).
    • Temporary roads would no longer change the usage of a property, such that a temporary road would no longer require a Record of Site Condition before being converted to a residential land use (provided they were not originally used for a less sensitive land use).
  • O. Reg. 153/04 would be amended such that an applicable site condition standard is deemed not to have been exceeded if a Qualified Person determines that the standard is exceeded at a property solely because the substance is associated with drinking water treatment.
    • This exemption removes the applicable site condition standard for contaminants that are present due to drinking water treatment (e.g. contamination resulting from a water main break). Example parameters could include chloroform, bromodichloromethane, dibromochloromethane, and bromoform.
  • O. Reg. 153/04 would be amended to indicate that an applicable site condition standard is deemed not to have been exceeded if a Qualified Person demonstrates that the standard is exceeded at the property solely because of the deposition of fill prior to environmental site assessments and that the concentration of a substance in the fill does not exceed naturally occurring concentrations of that substance found within the municipality or an adjacent municipality.
  • Subsection 1 (3) of O. Reg. 153/04 would be amended to replace “day-care centre” with “child care centre”, and subsection 1 (1) would be amended to add the term “child care centre”; that term would be defined as it is defined in the Child Care and Early Years Act, 2014.
  • O. Reg. 153/04 would be amended to remove buildings used for indoor gatherings of people for religious purposes from “community use” and add them to the definition of “institutional use”.
    • Churches may no longer require a Record of Site Condition to be converted into a residential land use.
