Brad Riddoch takes over as creative director of Bates Canada in Toronto next month.

Copywriter Riddoch has been acting creative director at MacLaren:Lintas since Bill Durnan left earlier this year.

Peter Lanyon, most recently creative director at Lanyon Phillips Brink in Vancouver, takes over as president of MacLaren:Lintas Aug. 1.

Riddoch has been with MacLaren:Lintas for two and a half years.

He was with J. Walter Thompson for two and a half years before that and spent 18 months with Creative Interchange after his first seven-year stint with jwt.

Riddoch replaces Bill Maynard, who joined Bates in January 1992 as executive creative director and will consult with Bates New York and Canada on a project basis.

Maynard’s contract expired earlier this year but remained with the firm until a replacement was found and will continue to consult with Bates New York and Canada on a project basis.

Maynard’s long list of senior responsibilities at ad agencies includes four years as vice-chairman director of creative services, Ted Bates Worldwide, and executive vice-president, managing director, creative services of Ted Bates New York.
