Supplemental Information


The Chemicals Management Plan (CMP) is a Government of Canada initiative aimed at reducing the risks posed by chemicals to Canadians and their environment. A key element of the Chemicals Management Plan is the monitoring and surveillance of levels of harmful chemicals in Canadians and their environment. Monitoring and surveillance are essential to identify and track exposure to hazards in the environment and associated health implications. Monitoring and surveillance programs provide the basis for making sound and effective public health and environmental health policies and interventions, as well as measuring the efficacy of control measures.


In support of the Chemicals Management Plan, monitoring and surveillance initiatives were established to support Health Canada and Environment and Climate Change Canada scientists, in collaboration with external partners and researchers, to advance our knowledge. This initiative has allowed the Government of Canada to increase its commitment to a number of existing monitoring initiatives, as well as to support new efforts.

Data on cannabis adverse reactions

Adverse reaction data with respect to cannabis products are one of several important indicators of the impact of legalization and regulation of cannabis on the health and safety of Canadian consumers and the risks associated with the real-world use of these products.

Health Canada conducts near-time monitoring, detection, and assessment of cases of adverse reactions involving cannabis products as part of the Vigilance Framework for Cannabis Products in Canada. Health Canada also monitors cases involving cannabis as a substance for broader issues of public health importance such as vaping-associated lung illness (https://www.canada.ca/en/public-health/services/diseases/vaping-pulmonary-illness.html), cases involving pediatric populations from studies like the study on serious and life-threatening events associated with non-medical (recreational) cannabis use in Canadian children and youth(https://cpsp.cps.ca/surveillance/study-etude/serious-and-life-threatening-events-associated-with-non-medical-recreational-cannabis-use-in-canadian-children-and-youth), and other potential emerging safety issues (for example, potential drug interactions, like cannabis and warfarin)(https://www.canada.ca/en/health-canada/services/drugs-health-products/medeffect-canada/health-product-infowatch/october-2020.html). Adverse reaction data are often used in combination with other sources of data (for example, published literature, hospitalization data and survey data) to better understand cannabis use behaviours among Canadian consumers and their potential risks.

The purpose of these annual surveillance reports is to provide a descriptive analysis of the types of adverse reaction reports involving cannabis products regulated under the Cannabis Act and its Regulations that are received by Health Canada to address gaps in current knowledge about the risks associated with use of cannabis products for medical and non-medical purposes. These annual surveillance reports are intended for use by a broad range of stakeholders such as licence holders, health care professionals, the public and others, including regulators, poison control centres, provincial and territorial stakeholders, and researchers.

Census of seabird colonies on St. Helena Island, Nunavut, from 1973 to 2007

St. Helena Island supports nationally significant populations of northern fulmar (Fulmarus glacialis), Thayer’s gull (Larus thayeri) and High Arctic brant (Branta bernicla hrota), as well as locally important numbers of other species including common eiders (Somateria mollissima borealis) and black guillemots (Cepphus grylle). To contribute to the understanding of seabird populations, Canadian Wildlife Service and partners conducted colony surveys on St. Helena Island, Nunavut, from 2002 to 2007. Each summer, ECCC conducted a daily count of all bird species observed on the island, both at terrestrial sites and during scans of the polynya. 


The crew (2 - 4 people) landed and surveyed the island systematically on foot. This involved walking all shorelines and lowlands on the small islands, and scanning scree slopes and cliffs, to give complete coverage. All breeding birds (as indicated by birds on nests, or the presence of eggs) were recorded, and where breeding was not confirmed, individual counts of each species were noted. In 2003 and 2004, ground surveys on St. Helena Island were restricted to minimize disturbance of the nesting birds that were part of focal research, that is, observers not want to increase the chance that birds monitored for long-term study would abandon due to disturbance. Instead, the island was split into irregular sections (e.g. 25 × 40 m, varying due to terrain) which were counted from blinds or discreet locations using 10× binoculars or 60× spotting scopes (Mallory & Gilchrist 2005).


This dataset includes the seabird colony surveys conducted by CWS and one of the first census done on St. Helena Island by Nettleship in 1973 (Nettleship 1974).

Water Quality - Kouchibouguac

The Canadian Council of Ministers of the Environment (CCME) has designed a Water Quality Index (WQI) to translate complex water quality data into an overall integrated score from 0-100. This score is based on the number of measured variables, which have observations exceeding water quality thresholds (i.e., scope); the number of these exceedances in the dataset (i.e., frequency); and the magnitude by which the observations exceed the guidelines (i.e., amplitude). These water quality parameters are crucial indicators of the physical, chemical or biological conditions in aquatic systems and processes. The purpose of the water quality monitoring program at Kouchibouguac National Park is to use this index to calculate a score and evaluate the status of our freshwater ecosystems. The methods for this measure involve a once-a-month sampling, from May to November, of permanent stations in five tributaries: Kouchibouguacis River, Tweedie Brook, Black River, Rankin Brook, and Portage River. At each station, a number of water quality parameters are measured in situ as well as the collection of samples that are sent for laboratory analysis of chemical content three times a year in the Spring, Summer, and Fall to capture seasonal variation. In addition, ten key variables (i.e., total phosphorus, nitrate, dissolved oxygen, pH, total alkalinity, aluminium, calcium, total suspended solids, turbidity, total organic carbon) were selected to include in the WQI calculation in order to reflect the regional situation and account for possible natural or anthropogenic disturbances (e.g., eutrophication or oxygen deficits, acidification, land-use changes) related to deforestation, agriculture, and urbanization activities.
