For many, the Mount Polley mine is the most immediate concern when it comes to clean up. The 2014 tailings breach released 25 billion litres of waste into nearby waterways and forests.

In 2017, Imperial Metals estimated a total of $67.4 million had been spent in clean-up costs for the Mount Polley spill. Of that, $15.5 million has been paid directly by government departments, with another $23.6 million eligible for tax refunds.
