Stream 0 substances in the Petroleum Sector Stream Approach
Stream 0 substances under the Petroleum Sector Stream Approach are not produced by the petroleum sector. They were identified during the initial triage because they arise from processes that are similar to those used in the petroleum sector and are considered to be of unknown or variable composition, complex reaction products or biological materials (UVCBs). Refer to the Petroleum Sector Stream Approach Substances List.

Regulations
Certain Products Containing Toxic Substances Regulations
In March 2025, the Certain Products Containing Toxic Substances Regulations were published. The regulations prohibit the manufacture, import, and sale of certain coal tar-based sealant products and certain sealant products containing PAH levels above 1,000 parts per million.
In November 2023, the proposed Certain Products Containing Toxic Substances Regulations were published for a 70-day public comment period.
Comments and information received during the public comment period were considered in the development of the final regulations.
Adding substances to Schedule 1
Coal tars and their distillates have been added to Part 2 of Schedule 1 to CEPA.
- Final order adding coal tars and their distillates: Canada Gazette, Part II: vol. 159, No. 1 – January 1, 2025.

Consultation documents
Proposed regulations for Polycyclic Aromatic Hydrocarbons (PAHs) in sealant products
In August 2022, a Proposed regulations for Polycyclic Aromatic Hydrocarbons (PAHs) in sealant products: consultation document was published for a 60-day consultation period. The purpose of this consultation was to complement the consultation document on the proposed Regulations for Coal Tar-based Sealant Products by informing stakeholders and soliciting feedback on the key elements to regulate PAHs in pavement and roofing sealant products, in addition to coal tars and their distillates.
Comments and information received during the consultation were considered in the development of the proposed regulations.
Proposed regulations for coal tar-based sealant products
In December 2021, a Proposed regulations for coal tar-based sealant products: consultation document was published for a 60-day consultation period. The purpose of this consultation was to inform stakeholders and solicit feedback on the key elements of proposed regulations for coal tar-based sealant products.
Comments and information received during the consultation were considered in the development of the proposed regulations.
Final screening assessment and risk management approach
Coal tars and their distillates
In June 2021, the Final Screening Assessment for Coal Tars and their Distillates was released and the related notice was published in the Canada Gazette, Part I: Vol. 155, No. 26 – June 26, 2021. The conclusions of the assessment are considered to cover all coal tars and their distillates, including but not limited to the 6 substances specifically identified in the assessment.
The final screening assessment concluded that coal tars and their distillates meet 1 or more criteria set out in section 64 of CEPA; therefore, the Government has added these substances to Part 2 of Schedule 1 to CEPA.
A proposed risk management approach was also released for a 60-day public comment period. Comments and the Government's response relating to general themes on the proposed risk management approach are provided in the summary of public comments received on the proposed risk management approach.
In June 2016, the Draft Screening Assessment for Coal tars and their Distillates was released and the related notice was published in the Canada Gazette, Part I: Vol. 150, No. 24 - June 11, 2016. A risk management scope was also released in conjunction with this publication. There was a 60-day public comment period associated with these publications.
