Burdett “Burd” Sisler, the oldest known living Canadian — and one of the world’s oldest Second World War veterans — has died at 110, his family confirmed on Saturday.

The supercentenarian from Fort Erie, Ont., died of natural causes on Thursday, less than two weeks before his 111th birthday.

“It’s certainly bittersweet. We were blessed to have him for so long,” his son, Norm Sisler, told CBC News.

“He will be missed by so many in our community and at the Legion. He made quite an impact on quite a few people.”

Oldest Canadian’s life advice is don’t drink, don’t smoke, and bowl until 103

At 110, Burd Sisler is now Canada’s oldest person. The Ontario resident worked as a border agent for 30 years and was also a veteran of the Second World War. His advice for staying healthy is to take care of your body. He stayed active by bowling into his 100s.

Sisler was born April 13, 1915, in Akron, Ohio, before his family moved to Ontario in 1918. He previously told CBC News that on his 105th birthday he decided his goal was to make it to 110 — a goal he accomplished.

At the time of his 110th birthday, he had five children, 11 grandchildren, 22 great-grandchildren and 14 great-great-grandchildren, by the family’s count. His wife Mae died in 1985.

Sisler had lived through both world wars, and got married just days after Britain declared war on Germany in 1939. He enlisted and travelled to Nova Scotia for training.

“He never got overseas or there’s a good chance I wouldn’t be here,” son Norm Sisler said in a previous interview with CBC News.

Burdett Sisler worked for the military after the war before starting a job as a customs agent as an appraiser at the Peace Bridge port of entry in Fort Erie.  He retired more than 45 years ago.

Last year, Canada Border Services Agency sent greetings to their former agent. “Happy Birthday Mr. Sisler, and thank you for your service!” a CBSA Facebook post said at the time.

Sisler once told CBC News that the world had “changed beyond recognition” during his lifetime.

“It was a sensible place to be at one time. When I look at the news and the weather, everything seems to be out of line. Nobody seems to think about the other person. He only thinks about himself and how much money he can grab,” he said in April 2025.

The beloved veteran drove until he turned 100 and lived in his own home until about 107, with family members helping him get through the COVID-19 pandemic. He stayed active and engaged, including by following the news and calling bingo.

His big piece of life advice? “Everything everyone does matters,” he said, adding that people should treat others the way they’d like to be treated.

As well, he said, don’t drink, don’t smoke — but take up bowling.

A funeral is scheduled for April 9 at Benner Funeral Home in Fort Erie.
