Murray Sinclair, who was born when Indigenous people did not yet have the right to vote, grew up to become one of the most decorated and influential people to work in Indigenous justice and advocacy.

A former judge and senator, one of Sinclair鈥檚 biggest roles was chair of the Truth and Reconciliation Commission into residential schools.

He died Monday morning in a Winnipeg hospital, said his son Niigaan Sinclair. He was 73.

Sinclair was a father of five and a grandfather.

His traditional Anishinaabe name was Mizhana Gheezhik or The One Who Speaks of Pictures in the Sky.

Born in 1951, Sinclair was raised on the former St. Peter鈥檚 Indian Reserve north of Winnipeg. He was a member of Peguis First Nation.

He was raised by his grandparents and graduated from a high school in Selkirk, Man., where he excelled in athletics.

Some of his earliest childhood memories were published earlier this year in his memoir, 鈥淲ho We Are: Four Questions for a Life and a Nation.鈥�

In it, Sinclair described discrimination he experienced being Anishinaabe in a non-Indigenous school.

鈥淲hile I and others succeeded in that system, it was not without cost to our own humanity and our sense of self-respect. These are the legacies all of us find ourselves in today.鈥�

Sinclair later worked as an assistant to legislature member Howard Pawley, before Pawley became premier.

In 1979, Sinclair graduated law school at the University of Manitoba.

In 11 years, he became the first Indigenous judge in Manitoba 鈥� the second in Canada 鈥� when he was appointed an associate chief judge of the provincial court. In 2001, he rose to was then called the Court of Queen鈥檚 Bench.

In all, he spent 28 years as a judge.

He served as co-chair of the Aboriginal Justice Inquiry of Manitoba to examine whether the justice system was failing Indigenous people after the murder of Helen Betty Osborne and the police shooting death of J.J. Harper.

He also directed the complex Pediatric Cardiac Surgery Inquest into the deaths of 12 children at Winnipeg鈥檚 Health Sciences Centre.

In leading the Truth and Reconciliation Commission, he participated in hundreds of hearings across Canada and heard testimony from thousands of residential school survivors.

The commissioners released their widely influential final report in 2015, which described what took place at the institutions as cultural genocide and included 94 calls to action.

鈥淓ducation is the key to reconciliation,鈥� Sinclair said. 鈥淓ducation got us into this mess and education will get us out of it.鈥�

Two years later, he and the other commissioners received the Meritorious Service Cross for their work.

It was one of many recognitions Sinclair received over his career.

He was given a National Aboriginal Achievement Award, now the Indspire Awards, in the field of justice in 1994. In 2017, he received a lifetime achievement award from the organization.

He was also awarded the Manitoba Bar Association鈥檚 Equality Award in 2001 and the Canadian Bar Association鈥檚 president鈥檚 medal in 2018.

In 2016, Sinclair was appointed to the Senate. He retired from that role in 2021.

The following year, he received the Order of Canada for dedicating his life to championing Indigenous Peoples鈥� rights and freedoms.

In accepting that honour, Sinclair said he wanted to show the country that working on Indigenous issues requires a national effort.

鈥淲hen I speak to young people, I always tell them that we all have a responsibility to do the best that we can and to be the best that we can be,鈥� he said.

Sinclair limited his public engagements in recent years due to declining health.

In his memoir, Sinclair described living with congestive heart failure. Nerve damage led to him relying on a wheelchair.

His family recently posted a statement saying he had been in hospital for the last few months.

Sinclair spoke at the 2023 swearing-in ceremony of Manitoba Premier Wab Kinew, the first First Nations person to lead a province. Sinclair called the milestone 鈥淢anitoba鈥檚 true act of reconciliation鈥� that would usher in a 鈥渘ew phase.鈥�

鈥淭hat phase ultimately is going to lead to a relationship between Indigenous and non-Indigenous people in which we are able to show true respect to all of those who are here and all of those who come here.鈥�

Sinclair鈥檚 memoir was released in September. In it, he continued to challenge Canadians to take action.

鈥淲e know that making things better will not happen overnight. It will take generations. That鈥檚 how the damage was created and that鈥檚 how the damage will be fixed,鈥� Sinclair wrote.

鈥淏ut if we agree on the objective of reconciliation, and agree to work together, the work we do today will immeasurably strengthen the social fabric of Canada tomorrow.鈥�
