In April 2012 David McRobie announced expansion of ownership of the firm to include colleagues William Crompton, James Salem and Tony Fuso. Christopher Deimling and Jill Sparling were appointed as Associates joining Johanna Garwood.

In June 2012 Bill Crompton traveled to St. John’s, Newfoundland, where he was inducted as a fellow in the Royal Architectural Institute of Canada (RAIC) during the institute’s annual conference. This honour recognizes Bill’s many years’ service as an ORSA board member as well as mentor to OAA interns and an educator in the RAIC’s Syllabus Program. Congratulations Bill, FRAIC!
