This report discloses sustainability data for the fiscal year ending December 31, 2016. Assessment of material issues continued through the first quarter of 2017. The consolidated data for key indicators can be found in the Selected Performance Indicators table on page 128.

Unless otherwise stated, we report data for our operations on a 100% ownership basis (e.g., for a 97.5%-owned operation, 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.
