Unless otherwise stated, we report data for our operations on a 100% ownership basis (e.g., for 97.5%-owned operations, we report 100% of the data). Data is reported using the metric system and Canadian dollars, unless otherwise stated. Unless otherwise stated, all workforce data is limited to permanent and temporary employees.

Where available, we include comparative historical data to demonstrate trends. Historical data is reported based on the scope of the report for the respective year. The scope of the report can change year to year, depending on acquisitions or sales of assets. In our efforts to continually improve and standardize our annual reporting process, the interpretation of data from year to year can often change. Certain comparative amounts for prior years have been reclassified or restated to conform to the presentation adopted for this reporting period.


1. A legacy property is defined as a property previously explored, constructed, operated or acquired by Teck. These properties are not expected to become active again and are permanently closed. The category also includes inactive properties that are no longer under exploration or development but may become active in the future. Currently, we actively manage 35 legacy properties.
2. Teck completed the sale of its 21.3% stake in Fort Hills on February 2, 2023; therefore, it is not covered in this report.
