Peter Byrne, a copywriter and creative director with Toronto-based Einstein Brothers, is now working out of ad agency MacLaren:Lintas, Toronto.

It is understood Byrne has signed a three-month contract with MacLaren.

Though he will be there full-time, Byrne will continue to honor his commitments on several on-going projects that he handles for the Einsteins, a communications company that specializes in audio production.

Byrne’s contract is believed to carry an option for another three-month renewal.

Byrne moved to the Einsteins from Ambrose Carr Linton Kelly, where he was responsible for a number of highly acclaimed ad campaigns for such clients as The Sports Network and W.K. Buckley.
