We synthesize the information available from the peer-reviewed literature on the ecological status of lakes and rivers in the oil sands region (OSR) of Canada. The majority of the research from the OSR has been performed in or near the minable region and examines the concentrations, flux, or enrichment of contaminants of concern (CoCs). Proximity to oil sands facilities and the beginning of commercial activities tend to be associated with greater estimates of CoCs across studies.

Over the past decades, concerns regarding the local and cumulative impacts of oil sands development have been increasing. These concerns reflect the industry's emissions, land disturbance, water use, and the resulting impacts to Indigenous Rights. Effective environmental management is essential to address and ultimately manage these concerns.

- Arctic lakes have shown significant ecological changes due to 20th-century climate change, and this study compares these changes with alpine and boreal lakes while considering factors like reactive nitrogen deposition.
- The research synthesized 52 diatom sediment records from various ecosystems in North America and Greenland, revealing that diatom diversity in arctic and alpine lakes significantly increased in the 20th century compared to previous centuries.
- Findings indicate that changes in diatom diversity aren’t strongly linked to specific environmental parameters, leading the authors to use Principal Components Analysis to understand the broader impacts of factors like nitrogen deposition and temperature trends.
