Neil Fowler, a former Toronto Sun CEO and publisher, is retiring as editor of the monthly British Which? Magazine after a three-year stay.
Fowler left the Sun in the fall of 2005 and was appointed editor of Which? in January of 2006, returning to his UK roots. Which? has a circulation of about 500,000.
When his Which? appointment was announced, Fowler said: "I'm very pleased to be joining Which? It has one of the highest trust ratings of any product in the UK - so it is a huge responsibility."
He once told Press Gazette editing Which? was "one of the best jobs in journalism."
"I think in journalistic terms it's as near to pure traditional journalism as there is. We don't take advertising, we are not for profit and we sell purely on the basis of how good the magazine is."
Now 52, Fowler says it is time for him to take a "bit of a break" from editing.
"I've been editing for 23 years and I'm having a bit of break and seeing if those skills are transferable. Which? is doing really well, I'm leaving it at a time when the sales are doing well. I want to see what else is out there."
Prior to his Sun run, his UK editing jobs included the Lincolnshire Echo, the Derby Evening Mail, the Journal in Newcastle and the Cardiff-based Western Mail.
