MJMA has developed a consistent 30-year legacy of design excellence developing hybrid public spaces that form the civic anchors and social focus of communities.
MJMA is an interdisciplinary architecture and design firm focused on designing high quality public space. Our integrated studio includes architecture, urban design, landscape architecture, interior design, digital practice, community engagement, and environmental graphic design, all aimed at delivering full service, holistic design solutions.

The firm’s projects are located across the country and expanding internationally with increasing formal international recognition of design excellence. The core community-based typology has evolved over the last ten years establishing further delineated expertise in Post-Secondary Academic and Library realms. We strive to continually innovate and explore opportunities to create unique forms of social and community space.

MJMA (MacLennan Jaunkalns Miller Architects) was founded in 1988 by John MacLennan, former Senior Partner at Sperry MacLennan Architects and by Viktors Jaunkalns and David Miller, then former Senior Associates with A.J. Diamond & Partners. The firm started with the competition-winning award of the Grand River Recreation Complex in Kitchener Waterloo. This first project went on to win the 1988 Canadian Architect Grand Jury Prize Award and its associated cash prize helped to sustain a fledgling three-person practice to continue on a path of design excellence within the aquatic and community recreation project type. Andrew Filarski and Robert Allen joined the firm as original staff members in 1989 and 1990 respectively, with Ted Watson joining in 1996. The firm continued to innovate and lead advancement and definition of the project type, growing a large portfolio of sport, recreation, community and academic work within Ontario. In 2009, with the retirement of John MacLennan, Andrew, Robert, and Ted joined as partners. In 2018, with the retirement of David Miller, Timothy Belanger became partner, establishing the firm’s current leadership structure.
