Aspire
Since its founding by Alexander Temporale, ATA Architects Inc. has embodied the belief that architecture should always reach higher—toward more meaningful places, more sustainable futures, and more connected communities. This spirit of aspiration has driven the firm to deliver bold yet contextually sensitive designs across a wide spectrum of sectors, including residential, education, heritage, civic, and institutional projects. With an office strategically located to serve the Greater Toronto and Hamilton Area, ATA has built a reputation for creating design solutions that are enduring, uplifting, and transformative. This forward-thinking approach is evident in landmark projects such as the adaptive reuse of St. Mark’s Church in Hamilton, and the rejuvenation of the Harding Waterfront Estate. Each of these projects reflects ATA’s commitment to blending vision with responsibility—aspiring not only to architectural excellence but also to cultural, environmental, and social impact. Their leadership in heritage restoration, ecological technologies, and public architecture reflects a continuous drive to challenge convention and push the boundaries of what buildings can do and mean for their communities.
Trust
Trust is the foundation of ATA Architects’ long-standing relationships with clients, institutions, and municipalities across Ontario. The firm’s integrated design process is grounded in deep listening, collaboration, and responsiveness—ensuring that every project reflects the values and aspirations of its stakeholders. Clients such as McMaster University, York University, Humber College, the City of Toronto, the City of Vaughan and the City of Mississauga have repeatedly returned to ATA for their expertise in new buildings, complex renovations, heritage-sensitive work, and high-performance design. ATA brings together architecture, interior design, heritage conservation, and ecological design under one roof, offering clients the clarity and confidence of a coordinated and experienced team. In projects such as the St. Catherine of Siena Church in Hamilton or the transformation of Humber College’s live campus spaces, ATA’s team navigates tight timelines, occupied sites, and intricate building systems with a calm professionalism rooted in experience. Their use of BIM modeling, 3D visualizations, and energy performance simulations fosters transparency, while their stakeholder engagement strategies ensure all voices are heard—from public consultations to student and faculty input. This ability to build trust through both technical excellence and human connection is what continues to distinguish ATA across the architectural landscape.
Achieve
ATA Architects’ work is defined not just by ambition and collaboration, but by the consistent achievement of meaningful, award-winning outcomes. The firm has received numerous accolades, including the Lieutenant Governor’s Ontario Heritage Trust Award for the Harding Waterfront Estate restoration, the Design Exchange Award for the Don Montgomery Youth Centre, and a City of Vaughan Urban Design Award for the Maple Library. These projects—and many more—showcase ATA’s ability to deliver on the full promise of a design, from conception through to construction. Their work is as technically sophisticated as it is socially and environmentally attuned, whether achieving zero-carbon targets at Vaughan Firehall 7-1 or crafting warm, inclusive spaces for youth and newcomers. Each project is an opportunity to realize something enduring: not just a structure, but a contribution to civic life, environmental stewardship, and community pride. Internally, ATA supports this mission through a highly collaborative team culture and a dual-team approach that enables parallel workflows for design and heritage—allowing them to meet complex deadlines without compromise. From detailed heritage documentation to cutting-edge sustainability research and prefabricated construction methods, ATA achieves success by bringing together tradition, technology, and purpose-driven design. The firm’s mantra—Aspire, Trust, Achieve—is not just a tagline, but a proven process that turns vision into reality, time and again.
