Micro-organisms and the Chemicals Management Plan
Micro-organisms are broadly defined as bacteria, fungi, yeasts, protozoa, algae, viruses, eukaryotic cell culture, and any culture other than a pure culture. As with chemicals, new and existing micro-organisms must undergo a screening assessment under the Canadian Environmental Protection Act, 1999 (CEPA 1999) to determine whether they can cause harm to human health or the environment.
As part of the Chemicals Management Plan (CMP), the 68 micro-organism strains on the Domestic Substances List (DSL) will be assessed. The Government of Canada used known hazard characteristics to rank the micro-organism strains into groups that determine their priority for assessment. The criteria used to rank the micro-organism strains are described in the Prioritization of Micro-organism Strains on the Domestic Substances List.
A Two-year Rolling Risk Assessment Publication Plan for the Remaining Existing Living Organisms to be Assessed under CEPA (2017-2019) is available. This plan outlines proposed publication dates for both draft and final screening assessments of existing micro-organisms. It will be updated yearly.
Screening assessment process
The steps used to conduct science-based risk assessments of micro-organism strains on the DSL are described in the Framework for Science-Based Risk Assessment of Micro-organisms regulated under the Canadian Environmental Protection Act, 1999.
Once complete, screening assessments undergo scientific review by both governmental and non-governmental experts. This review process ensures that the screening assessments are scientifically sound, complete, and based on the most up-to-date information.
As a result of the screening assessment process, the DSL may be amended from time to time to indicate that the Significant New Activity (SNAc) provisions of CEPA 1999 apply to some existing micro-organism strains. For more details on the screening assessment process, please refer to the general information on the screening assessments of micro-organisms on the Domestic Substances List.
Micro-organisms strains that are not listed on the DSL are considered 'new'. Read about how new substances and new micro-organisms are assessed and managed.
2017 Mandatory Section 71 Notice
In September 2017, a notice was issued in the Canada Gazette, Part I: Vol.151, No. 38 – September 23, 2017 under section 71 of CEPA 1999. The notice applies to 11 micro-organisms.
This notice will collect critical information on commercial status, downstream use and yearly market fluctuations between 2013 and 2016 in order to help inform future risk management activities.
2009 Mandatory Section 71 Notice
In October 2009, a notice was issued in the Canada Gazette, Part I: Vol.143, No.40 - October 3, 2009 under section 71 of CEPA 1999. The notice applied to approximately 45 animate substances (micro-organisms).
The notice collected data from those that manufactured or imported micro-organisms, whether alone, in a mixture or in a product during the 2008 calendar year, complementing information collected or generated as part of the DSL categorization process, in order to inform prioritization of the substances and subsequent risk assessment and risk management activities.
The following are examples of products that may contain new and existing micro-organisms that may be subject to CEPA 1999. Please note that these lists are not exhaustive.
