In his long career with MTA, Po has applied his excellent technical and organizational skills to keep complex schedule-driven projects on track. Among many other accomplishments, Po was critical to the realization of the Wynford Drive Campus Project (the Aga Khan Museum and Ismaili Centre) in Toronto—a spiritual and cultural landmark six years in the making. Conceived in collaboration with the renowned international architects Fumihiko Maki and Charles Correa, the project required mastery of technically exacting design standards and exceptionally precise construction with minimum tolerances. Po is now leading another large-scale, complex project – Ottawa’s West Memorial Building, which will become the temporary home for Canada’s Supreme Court.

Phil Silverstein brings a wealth of experience as Contract Administrator, Designer and Job Captain of Ontario university buildings and complex, multi-phase renovation and expansion projects.

Phil’s integrated approach to design, comprehensive understanding of building science, efficient working methods, his ability to work in a wide range of scales, and his personable client / construction team interface skills have made him a skilled team leader.

Louis Lortie | B.E.D.S, B.Arch, OAA, OAQ, MRAIC
Senior Associate
Louis Lortie is one of MTA’s most experienced architects, with nearly 20 years with the firm and more than 30 in the profession. His career has centred around the construction of large and complex projects where he was involved in the preparation and coordination of construction documents followed by the responsibilities of site administration and review of construction. His experience with the construction administration process has provided him a thorough understanding of buildability issues and a keen eye for detail which he brings back into the other phases of the design process – making seemingly challenging details feasible. In recent years, Louis has worked as a studio-wide QA/QC resource, ensuring that all MTA projects are drawn to an exacting standard. A highlight in a career full of them, Louis distinguished himself on the landmark Canadian War Museum project in Ottawa, published worldwide and a recipient of the Governor General’s Medal, Canada’s highest architectural award.

As Contract Administrator and Project Manager, Janice Chan has played a key role in completing MTA’s most complex and exacting projects. A testament to her effective communication skills and attention to detail, Janice worked closely in collaboration with internationally renowned architects Maki and Associates to realize Toronto’s landmark Aga Khan Museum. Janice’s proven communication skills, comprehensive knowledge of building technology and construction experience have made her a go-to expert for large scale projects such as the Ismaili Centre and the new Canon Canada Headquarters in Brampton, and she is now spearheading the project specifications and construction administration efforts for the complex of buildings MTA has designed for the Gordie Howe International Bridge.


Mary O’Malley | B.S.Arch., M.Arch., LEED AP BD+C

A true team player, Mary’s inexhaustible ability to listen and communicate complex ideas and information has been a vital element to the success of all projects she has been involved with.


Sean Robbins | B.Arch.Sci., M.Arch. (Hons)
Sean has brought a new level of coordination and skill to our BIM design work since joining MTA as BIM Manager in 2016. His duties have included Revit integration, best practices, project support, proactive standards development, complex systems integration, BIM coordination, content creation, in-house training, troubleshooting and construction document production. In addition to his project experience, Sean instructs internationally trained architects and technologists through BIM in Professional Practice at Ryerson University — a position that he has held since 2013.
