Harron's eldest daughter Martha said her father died yesterday morning surrounded by family at his Toronto home after choosing not to seek treatment for cancer.
The wit and humour that landed him roles on CBC radio and television programs continued to define her father to the very end, Martha Harron said.
"He was still sharp. He was still capable of being funny even though his voice was barely above a whisper," she said.
Harron introduced his Farquharson character, a country bumpkin from rural Ontario dressed in a frayed grey cardigan sweater who poked fun at almost anything Canadian, on a CBC television revue in 1952, drawing inspiration from a stint working on an Ontario farm.

He went on to perform as Farquharson on the long-running US TV variety show "Hee Haw." He also wrote many books under the name of Charlie Farquharson.
He also appeared regularly on US TV shows in the 1960s, including "The FBI," "Mission Impossible," "12 O'Clock High," "The Outer Limits," and "Dr. Kildare."
"I said I'd been reading a book to my kids called 'Anne of Green Gables' and it seems to me that this little girl has such an imagination that the only way you can really realise it would be in song," Harron recalled in a 2014 Canadian Press interview.
Nine years later, the TV version was adapted into a stage production.
The play has been performed for more than 50 consecutive years at the Charlottetown Festival on Prince Edward Island, a fact Harron sees as a stroke of good fortune.
Harron was born in Toronto in 1924 and, according to his own accounts in past interviews, got his start in show business at an early age.
Harron began his career as a cartoonist drawing caricatures of people at banquets in the 30s before landing an audition for CBC radio.
Cormier said Harron's intellectual passions nearly led him down a very different career path than the one that made him famous.
His passion for philosophy earned him scholastic awards at the University of Toronto.
