Simon Scott, head of marketing and communications at Northern office developer Bruntwood, is leaving to begin a new life with his family in Canada.
Scott said: "I've been visiting Canada to visit family for years and my wife and I think it will be a great place to bring up our daughters. The air is fresh, the mountains are spectacular, and in the winter we can ski every weekend."
Scott joined Bruntwood 12 years ago as marketing manager and was promoted to the executive board after leading the company's sponsorship of the Commonwealth Games in 2002.
He continued: "Whilst excited about what lies ahead, I leave with a heavy heart. If the research is to be believed, I am one of the statistical few who love what they do. Bruntwood has been like a family to me and Manchester my adopted home. I'll miss them both very much and hope I can replicate the sense of belonging I have enjoyed in Manchester, when I'm settled in Canada."
Chris Oglesby, chief executive of Bruntwood, added: "Simon has made a bold decision for his family and I am very sorry to be losing him. Since joining us 12 years ago, he has brought passion and commitment to everything he's done and has been a true asset to the company. Bruntwood is a family business and Simon has very much been part of our family. He's played a key role in our executive team and a far broader role in the cities. He leaves big shoes to fill and a legacy that won't be forgotten. We wish him, Sharon and the kids every success with their new life."
There was no announcement about a replacement.
