MacFarlane withdrew from the firm in 1912, and Robert Henry Macdonald became a partner.

He also did work with Parker & Thomas in Boston and Carrere & Hastings in New York before partnering with MacFarlane in Montreal.
He was also a member of the Royal Institute of British Architects, becoming an Associate in 1904 and a Fellow in 1913.
