Quebec faces $1.2 billion burden cleaning up hundreds of abandoned mines
A provincial audit finds Quebec’s Ministry of National Resources and Forests is failing to enforce mine-restoration rules, leaving the government liable for about $1.2 billion in cleanup costs.
Quebec’s auditor general has criticized the Ministry of National Resources and Forests for weak supervision of mining activities and poor enforcement of the Mining Act’s restoration provisions. Although companies must file rehabilitation plans and post financial guarantees before starting work, the audit shows many submissions are incomplete, updates are delayed, and guarantees do not reflect rising costs or inflation.
On average, plan revisions occur every seven and a half years, with four mines experiencing nine-year gaps. Experts argue that the guarantees are set far below the true expense of cleaning up large waste volumes, and the lack of a public comment period keeps these estimates opaque. The province now faces roughly $1.2 billion in liabilities for abandoned mines that were active before modern regulations were introduced. The ministry says an action plan is being drafted to improve its processes.
Why it matters
Taxpayers could bear huge costs if abandoned mines are not properly funded and overseen.
