Richler worked for many years as a radio documentary producer for BBC Radio, representing the organization at the Prix Futura and winning a Sony Award before following in his father's footsteps and becoming a writer. After returning to Canada in 1998, he was the books editor and then the literary columnist for the National Post. His book This is My Country, What's Yours? A Literary Atlas of Canada won the 2007 British Columbia's National Award for Canadian Non-Fiction. The book is a literary travelogue and cultural portrait of the country, for which he interviewed novelists and storytellers from Newfoundland to British Columbia and the Inuit Arctic. He also produced and presented a ten-part series for the CBC Radio program Ideas based on his research.
He has contributed to numerous publications in Britain, including The Guardian, Punch and The Daily Telegraph, and in Canada, The Walrus, Maisonneuve, Saturday Night, the Toronto Star, and The Globe and Mail.
He lives in Toronto with his wife, House of Anansi publisher Sarah MacLachlan. Richler stood as a candidate for the New Democratic Party of Canada in the Toronto electoral district of St. Paul's in the 2015 federal election. In 2016 he published The Candidate: Fear and Loathing on the Campaign Trail, a memoir of his experience on the campaign trail. The book was a shortlisted finalist for the 2016 Shaughnessy Cohen Prize for Political Writing.
