Osler’s Regulatory, Indigenous and Environmental Group possesses extensive knowledge and decades of accumulated experience advising clients on a broad range of issues. Relying on their own individual skills and drawing on each other’s expertise and experience, the team’s lawyers provide clients with thorough, comprehensive and seamless assistance.

Working as an integrated group across the country, Osler’s Regulatory, Indigenous and Environmental lawyers advise clients on their energy, natural resource and infrastructure matters including:

  • Mining

As environmental issues continue to be at the forefront of public and political discussion, there are increasing regulatory, civil and reputational risks and liabilities relating to projects, facilities and operations, as well as potential penalties for environmental offences in Canada. Governments at both the Federal and Provincial levels have increased their focus on environmental enforcement and are seeking stiff penalties for individuals and corporations that allegedly break environmental laws. Should you need assistance in this area the group can also help with:

  • Environmental litigation and dispute resolution
  • Responding to environmental incidents, regulatory inspections and investigations
  • Conducting internal investigations into potential environmental non-compliances
  • Environmental enforcement and defence of prosecutions
