Let us reintroduce ourselves.

We have embarked on a new chapter as Cochrane Sinclair LLP, honouring the legacies of Murray Sinclair and Harold (Sonny) Cochrane. Guided by their transformative leadership, we continue to lead in Indigenous, Public and Constitutional Law, blending innovation with tradition to pursue justice and reconciliation.

We challenge the status quo.

Every case we take reflects a deeper responsibility — we answer the 94 Calls to Action laid out by our General Counsel, Murray Sinclair, when he was the Chief Commissioner of the Truth and Reconciliation Commission. These calls shape every aspect of our work, from class actions on child welfare to the preservation of First Nation languages and redefining treaty relationships for future generations.

Empowering Indigenous Futures

Once absent from the courtroom, Indigenous voices now lead in reshaping law. We lead with integrity, tackle difficult cases, and educate courts, governments, and law students to better understand Indigenous law and experiences. As Murray Sinclair reminds us, “Innovation isn’t always about creating something new… Sometimes, it involves looking back at our old ways and bringing them forward.

Building Partnerships with Purpose

Our mission goes beyond litigation. Through collaboration and meaningful partnerships, we support communities, businesses, and governments in achieving their goals. By providing expert legal solutions, we empower Indigenous futures and strengthen nation-to-nation relationships.

Transforming Lives with Compassion & Expertise

We confront historic and current injustices — from class actions on the Millennium Scoop to challenging systemic barriers in criminal justice. Our work isn’t just about addressing the past; it’s about building relationships of mutual respect and shared responsibility that shape the future.

Shaping Justice Through Innovation & Integrity

Cochrane Sinclair LLP is part of a larger movement for justice, driven by the legacies of our leaders and the power of Indigenous knowledge. Our work builds bridges between tradition and progress, ensuring Canada’s legal system evolves with the communities it serves.

Rooted in Tradition

Our strength lies in the traditions and teachings passed down through generations. We honor these roots not only in the cases we fight but in the spaces we create — offices where Indigenous law and values thrive. Our practice reflects the deep knowledge of our people, ensuring that the stories and voices of our communities shape the legal landscape. Inspired by leaders like Sonny Cochrane and Murray Sinclair, we carry forward a mission grounded in resilience and respect for the past.

Leading the Future

The future demands bold action, and Cochrane Sinclair LLP stands ready to meet the challenge. We believe in the power of reconciliation through law — not as an abstract goal, but as a living practice woven into every case we take on. As we reshape systems and support Indigenous communities, we lay the foundation for future generations. In our work, we blend tradition with innovation, ensuring that equity, justice, and Indigenous sovereignty remain central to Canada’s evolving legal system. Together, we build a future where all communities can thrive.

“As Grand Chief, I’ve witnessed firsthand the tremendous impact Cochrane Sinclair LLP has had on advancing the rights of First Nation people and communities.
