He publicly voiced concern over access to justice for the working poor and middle class who earn too much to qualify for legal aid but not enough to afford a lawyer.[7] He also called for the legal system to engage the narratives and laws of Indigenous Canadians "with a sense of humility".[8]
He authored the lone dissenting opinion when, in October 2013, the Court of Appeal overturned the Carter v Canada (AG) judgment at first instance, which had found in favour of permitting assisted suicide in Canada. Finch wrote that "[t]he point at which the meaning of life is lost, when life's positive attributes are so diminished as to render life valueless, when suffering overwhelms all else, is an intensely personal decision which 'everyone' has the right to make for him or herself".[9] The case proceeded to the Supreme Court of Canada, which agreed with Finch's position when it reversed the decision of the Court of Appeal in 2015.[10]
Finch returned to private practice in 2013, upon reaching statutory retirement age.[11]
Finch was married to Judy; together, they had three children.[8] He died on August 30, 2020, surrounded by his family.[3] He was 82, and suffered from cancer in the years leading up to his death.[8]
