Indigenous Law


Sacha is a member of the English River First Nation, a Dene community located in Northern Saskatchewan. His long-standing interest in Indigenous issues has resulted in an Aboriginal law practice. Sacha has experience working for resource developers, such as mining companies, forestry companies, and hydro-electric utilities, in engaging with First Nations and Metis communities, particularly when it comes to future resource developments or the impacts of past developments.

In addition, Sacha has developed a practice respecting First Nation elections and governance issues. He has acted for Indigenous Governments/Tribunals in enforcing orders to remove people from Chief and Council and has acted for First Nation people in challenging elections.

Sacha has been a contributing editor to the Canadian Native Law Reporter, a publication that reports on Indigenous law cases, as of 2015.


Public Law/Administrative Law


Sacha’s work in Aboriginal law ties into his practice in Public Law/Administrative law. Aboriginal law frequently engages principles of administrative law, such as duties of fairness. In addition to acting for Indigenous Tribunals, Sacha has acted for and provided advice to other administrative tribunals, such as Workers’ Compensation tribunals and Residential Tenancies tribunals.

In the area of Public law, Sacha has experience with human rights under human rights legislation and the Charter of Rights and Freedoms. For example, Sacha acted for Amnesty International in the case of Canada v. Khadr respecting “life, liberty and security of the person” rights under the Charter. Sacha has also acted for clients respecting addressing human rights issues, such as equality rights.


Insurance Law and Personal Injury


Sacha has acted for both public and private insurance companies. In this context, he has provided advice respecting the interpretation of insurance contracts and on the duty of good faith. He also provides advice to policyholders when insurers deny coverage. Sacha has experience with property insurance, liability insurance, disability insurance, and life insurance.

In addition to his insurance practice, Sacha teaches insurance law at Robson Hall, Faculty of Law, University of Manitoba.

Finally, Sacha has practiced in the area of personal injury in Manitoba, the Northwest Territories, and Nunavut.

In addition, Sacha defends people from personal injury claims as part of his insurance practice.
