Landscape Carbon Benchmarking Study received two prestigious awards from the Canadian Society of Landscape Architects (CSLA): a National Award in the category of Research, and the Jury’s Award of Excellence.

The study began with a focused question: how carbon intensive are the landscapes being reviewed through Toronto’s development application process? Commissioned by the City of Toronto, it creates a practical starting point for municipalities, practitioners, and policymakers to better understand lifecycle carbon in landscape design and move toward lower-carbon development landscapes across Canada.

“The jury felt that this Study truly advances the science, the practice and art of landscape architecture. The jury was particularly impressed with how the case study findings are communicated in a simple and clear language, to be widely understood and accessible to those outside of our profession. This will inspire others to apply the practical, yet science-based, principles to projects across Canada, resulting in measurable impacts to climate change. Most notably, this benchmark un-complicates carbon reduction and sequestration in urban landscapes and positions landscape architects as leaders of that change.”

The City of St. Catharines is studying how to renew Facer Street from Niagara Street to Grantham Avenue. DTAH and R.V. Anderson are leading the work, looking at how this street can become safer, greener, more comfortable to walk, and a stronger place for the neighbourhood.

Facer Street is more than a route through the city. It is a street where people live, shop, walk, gather, and connect. That is why this project is looking at both street safety and the public space experience.

Early analysis and concept options are now available, and public feedback will help shape the next steps. If you live near Facer Street or in St. Catharines, take a look and tell us what you think by filling out the survey below. The survey closes Thursday, April 30, 2026.

The new Children’s Garden at Evergreen Brick Works offers an exciting outdoor classroom for children to engage with the site’s ecological, Indigenous, and industrial heritage. DTAH led the Garden’s recent revitalization that integrated accessible seating, a gathering circle mosaic and fire pit by artist Ferruccio Sardella, and a feather-shaped arbour roof inspired by Anishinaabeg teachings – all designed to create an inclusive play space that fosters a sense of wonder and delight.

The Children’s Garden is part of a series of campus-wide updates led by DTAH and LGA Architectural Partners in joint venture. These updates seek to improve visitor experience, accessibility, and adaptability to evolving on-site programming for all ages and abilities. Projects underway include a new Welcome Centre; Ravine Centre; improvements to the TD Future Cities Centre and outdoor common areas.

Parks Canada, in partnership with the Royal Architectural Institute of Canada (RAIC), launched an international design competition to reimagine 10 contiguous lots in the heart of Banff National Park as a vibrant community space and visitor centre. In collaboration with Kengo Kuma and Associates (KKAA) and Paul Raff Studio, our team was selected as one of the six shortlisted teams to develop conceptual designs for Phase II of the competition.

The six conceptual designs are now available online for your feedback. Complete the survey by February 27th, 2026 to evaluate which proposal best reflects Banff’s character, incorporates Indigenous representation, and supports the local community.

DTAH is revitalizing Seaton Park for the Bloor-Annex BIA! The project builds on our previous work with the BIA on four award-winning parkettes, which transformed a series of underutilized sites into lush, ecologically functional green amenity spaces along Bloor Street West.

The proposed designs open the site along the southern and eastern edge to improve site lines, pedestrian flow, and opportunities for viewing murals and artwork along the laneway. Diverse seating options, new lighting, paved areas, and adaptive pollinator species are further introduced to create a safe, connective urban park for rest, contemplation, and social interaction. 

We want to hear your thoughts! If you have any questions or feedback on the designs, please email [email protected] by February 15, 2026 at 5 p.m.

DTAH is developing Markham’s first Complete Streets Design Guide!

Complete Streets prioritize people, challenge conventional transportation thinking, and influence every aspect of street design — no matter the scale or complexity. This project is a component of the Transportation Master Plan Update currently underway (led by HDR). DTAH is working closely with City staff and the broader team to prepare a guide that considers the ever-evolving Ontario context, the full range of possible street projects, and subjects such as micromobility and green infrastructure.

The guide will help Markham create safe, equitable streets that better connect communities, embed sustainability, and support the future growth of the city.
