We’re looking forward to opening our studio at 50 Park Road to the public for Doors Open Toronto, on Saturday, May 27, from 10:00 a.m.-5:00 p.m. with last admittance at 4:30 p.m.

We will also be offering free presentations throughout the day, sharing insights from some of our current projects in Toronto as part of the Toronto Society of Architects (TSA) Open Studio program.

11:00 a.m., Yvonne Lam: Transforming Toronto’s Waterfront: What’s next for East Bayfront, Quayside and Queens Quay East

1:00 p.m., Mark Langridge: A Bridge to Somewhere: Two crossings in ravine settings close to Yonge & Bloor

3:00 p.m., Megan Torza: Architecture in Parks: Designing for community use at Tommy Thompson Park, Dufferin Grove and Bluffer’s Beach

Visitors to DTAH’s studio will learn about the evolution of the important modernist building that sits in the Rosedale Valley ravine in the heart of downtown. See the working environment of a leading architecture, landscape architecture and urban design firm and the transformation of the original headquarters of the Ontario Association of Architects. Recognized as an OAA landmark building and listed as a heritage property, the building and site speak directly to DTAH's philosophy which for five decades has worked to respect, preserve, and enhance the public realm, while celebrating the intersection of built and natural form.

DTAH has had the honour of helping to shape many beloved places across the city, through our expertise in urban design, landscape architecture, and architecture. Projects that we have worked on which are also participating in Doors Open include: Artscape Wychwood Barns, Danforth Garage, Cummer Church, Fort York National Historic Site, and Parkdale Arts and Cultural Centre – part of the future Parkdale Hub.

DTAH is honoured and delighted to share that we are the recipients of two (!!) CSLA National Awards of Excellence, for St. Andrew's Playground Park and Brampton Riverwalk Open Space and Urban Design Master Plan.

The revitalized St. Andrew's Playground Park brings a playful landscape and much-needed greenspace to meet the needs of the dense and lively Fashion District. As the site of Toronto's first public playground, the new design honours the history of the site with heritage signage and adds whimsical bright yellow accents throughout, while protecting the landscape's interwoven tree canopy. With recent changes to the adjacent community, including the opening of the adjacent Ace Hotel and the upcoming mixed-use Waterworks Building food hall, residence and YMCA, the reimagined St. Andrew's Playground will now play a vital role as a dynamic community greenspace for generations to come.

The Brampton Riverwalk Open Space and Urban Design Master Plan re-imagines Brampton's relationship with a once-dynamic water-way, by re-introducing Etobicoke Creek into the identity of the downtown. The plan aims to create a vibrant place for people to enjoy and a catalytic resource that weaves through the city's core. The Master Plan highlights opportunities for an integrated landscape and provides a strong framework for the city to imagine new possibilities for its future growth. The result: A renewed physical and social relationship to the Etobicoke Creek through the creation of a series of new trails, look-outs and connections with increased physical and visual access to the water’s edge, as well as connectivity to (and between) adjacent neighbourhoods and the downtown, resulting in a renewed physical and social relationship to the Etobicoke Creek by way of a series of connected public spaces and landscapes.

April is Landscape Architecture Month and we are proud of the work we do to shape our communities, from master plans to the design and implementation of parks and plazas.

DTAH is excited to continue to build on our extensive experience with the City of Toronto and share that we are the successful proponents for the design and construction of two City of Toronto parks, located at 10 Ordnance Street and 801 Wellington Street West.

The two parcels of land are located just north of Garrison Crossing, an award-winning project in Fort York, which was led by Pedelta and Dufferin Construction with architectural and landscape components by DTAH.

These parks will complement Stanley Park to the north and Garrison Common to the south, creating a continuous corridor of green spaces spanning from Adelaide St. W to Fort York Blvd. and will be part of the active transportation route to Toronto’s waterfront farther south.

We are looking forward to collaborating with the City, the community and stakeholders to transform these spaces into dynamic and welcoming greenspaces for this growing community. Stay tuned for more updates!

DTAH is excited to work with our partners at Praxis Consulting to renew the 11th sequential Wascana Centre Master Plan in Regina, Saskatchewan.

Wascana Centre is located on the traditional lands of Treaty 4 territory, the original lands of the Cree, Ojibwe, Saulteaux, Dakota, Nakota, Lakota, and on the homeland of the Métis Nation.

Wascana Centre is a unique place in Canada and one of the country’s largest park systems. At 930 hectares, it is home to many uses, including the Provincial Legislative Grounds, the University of Regina, Saskatchewan Polytechnic, recreational facilities, museums, galleries, performing arts centres, and a federally protected waterfowl preserve. DTAH has had the privilege to lead all of the master plans since 1982. This effort, the first for the Saskatchewan Provincial Capital Commission, will include a 100-year vision alongside a focused set of recommendations to inform capital works over the next decade.

We are at the beginning of the process where we listen to the community. To date we have held one-on-one interviews with Indigenous Community Leaders, an Indigenous Sharing Circle, a well-attended public open house, and our first online survey. More opportunities to engage will take place throughout the year. The overall project is scheduled for completion by the end of 2023.

DTAH is pleased to announce that Partner Emeritus Robert (Bob) Allsopp has established the Robert N. Allsopp Urban Design Fellowship with the Landscape Architecture Canada Foundation (LACF). The one million dollar donation will allow LACF to award a yearly Fellowship of $35,000 to $50,000.

The Robert N. Allsopp Urban Design Fellowship is intended to provide a practicing mid-career landscape architect, whose work and exploratory interests are in urban design, with funds for research or pursuing a specific area of inquiry over a five-to-six-month ‘sabbatical’. The Fellowship will provide support for urban design research which elevates the art, science, and practice of landscape architecture, contributes to the knowledge base of the profession and is beyond the scope of the projects in their office or practice.

Bob Allsopp explains:

In establishing this Fellowship, my larger motive is to promote excellence in the landscape architecture profession particularly in urban design. I am offering an opportunity to seasoned urban designers to take a break from practice and to pursue areas of enquiry and research that are useful and invigorating to them personally, and that benefit the larger profession and ultimately, urban environments.

Click here to learn more about the Fellowship.

First Deadline for the Fellowship is 1 June 2023.

According to Eha Naylor, LACF President:

This extraordinary gift will advance awareness of landscape architect's role as leaders in thinking critically and creatively about urban design issues in our built and natural environments.

About Robert (Bob) N. Allsopp

Bob grew up in Leicester, England where he studied Architecture at the Leicester College of Art and Technology and was winner of the Royal Institute of British Architects Soane Medallion design competition following graduation. He became a registered architect in 1961 and completed his first major architectural commission two years later. He then pursued graduate studies in Civic Design at the University of Edinburgh, Scotland, followed by two years as Visiting Lecturer in Architecture at the University of Kansas, USA under the auspices of the Fulbright Scholarship Program. Returning to London, UK, he worked as an Architect/Planner on the planning of Redditch New Town and major urban regeneration projects in London and Cardiff. Bob moved to Canada in 1968 to take up the position of Director of Campus Planning at the University of Manitoba and subsequently became involved, with Alex Rattray, in establishing the graduate Landscape Architecture Program there. He taught the first design studio in that new program. In 1979, he joined Roger du Toit Architects/du Toit Associates in Toronto and began teaching in the Department of Landscape Architecture, University of Toronto. The partnership, du Toit Allsopp Hillier, was formed in 1985 and it continues as DTAH, a much-expanded, multi-dimensional design practice. Bob is principally known for his breadth of understanding of urban design issues and his doggedness in search of deceptively simple design solutions strongly rooted in their place. His best-known work is in campus planning, urban neighbourhoods and a wide range of projects in Canada’s National Capital recognized nationally and internationally. He is the recipient of CSLA Fellowship in 1995, the 2008 OALA Pinnacle Award and 2016 CSLA Lifetime Achievement Award.

Bob was recipient of the 1989 Canada Council’s Residency in Barcelona Award. It is the personal and professional value of this ‘sabbatical’ experience combined with his belief that Landscape Architecture is the best multi-dimensional ‘home’ for Urban Design, that has stimulated the establishment of this LACF Fellowship.

DTAH Partner James Roche contributed a chapter to a new book, Innate Terrain: Canadian Landscape Architecture, edited by Alissa North. In his chapter, James explores the transformation of Toronto's waterfront from an industrial land to a new vibrant community.

An open letter to Premier Ford and Minister Clark
Re: Bill 23 – More Homes Built Faster Act, 2022

We are writing to you as leading architects, landscape architects, and urban designers in Ontario.

The More Homes Built Faster Act, introduced on October 25, proposes extensive and significant legislative changes that would, if enacted, radically alter land use planning and city building in Ontario. The stated intention of this proposed legislation is to accelerate the construction of 1.5 million homes over the next 10 years to address our housing crisis.

We firmly believe that this legislation will not achieve its stated intent.

Instead, it will inhibit the construction of affordable housing in our province; dismantle regional planning and urban design considerations; undermine heritage protection, environmental protection, and climate change mitigation; and limit public participation in how we build our communities.

We have summarized our major concerns below:

Bill 23 will reduce the supply of truly affordable housing by reducing the affordable housing requirement in Inclusionary Zoning from 20% to 5%. The required period to maintain affordability is reduced from 99 to 25 years. This will exacerbate generational poverty and extend inequitable access to resources and infrastructure for the people of Ontario.

Bill 23 will encourage urban sprawl and undermine local democracy by effectively dissolving 50 years of regional planning in the Golden Horseshoe. This will certainly lead to a substantial conversion of farmlands, loss of green lands, and suburban sprawl.

Public participation will be limited by removing the requirement for a public meeting for plan of subdivision. The Minister will have new powers to amend Municipal Official Plans at any time, for any reason, without public consultation.

Bill 23 undermines environmental protection by limiting the role of Conservation Agencies to solely that of flooding and erosion hazards. Removed from their oversight will be watershed planning and management, coordinated flood protection, conservation of green lands and biodiversity, which are all core to climate change mitigation.

Bill 23 threatens the Greenbelt. There are 86,500 acres within the GTA currently zoned and ready for development. This is more than enough land available now that can be used to meet government targets. Housing construction needs to start without delay on these lands that are close to transit and urban services, where people already live, work and play.

Yet the government wants to remove 7400 acres of protected green space and farmland in the Greenbelt. Our Greenbelt lands protect the headwaters of the rivers flowing into Lake Ontario, preserve valuable farmland, connect forests and wetland ecosystems that form a continuous arc from the top of the GTA to the Niagara region, and limit suburban sprawl. The Greenbelt belongs to current and future generations of the people of Ontario.

Bill 23 removes design from the municipal approvals process. Exterior design, landscape and streetscape design should be reviewed during Site Plan Control. Design review at the municipal level is considered best practice nationally and internationally.

We must emphasize that design is not a superficial aesthetic overlay. It is fundamental problem-solving, directly related to the quality of the built environment, and to climate change mitigation. The design review process is critical in delivering safe, healthy, affordable, socially and environmentally sustainable communities to the people of Ontario.

We agree that the current system of municipal approvals needs to be streamlined to deliver urgently needed affordable housing. Bill 23 is not the way to do it. It needs to go back to the drawing board.

To effectively address our affordable housing crisis, we strongly urge the Government of Ontario to rethink Bill 23 and invite the Government to a robust and immediate consultation with leaders in our industry. In collaboration with municipal and provincial governments, we can produce the best possible outcomes for the people of Ontario.
