The City of Mississauga has published a draft Complete Streets Guide. DTAH is the lead consultant with a multi-disciplinary team that includes Michael King/Traffic Calmer, HDR, and LURA Consulting. The document will guide street design and decision-making, reflecting the needs and concerns of the community while incorporating best practice from national organizations, peer cities, and advocacy groups.

Complete Streets guidelines and policies ensure that all street users including pedestrians, cyclists, public transportation users and drivers are accommodated and feel comfortable and safe. Measures can include installing cycling facilities, building sidewalks, adding dedicated public transit lanes, and implementing measures to slow down traffic.

The City of Mississauga is conducting a short survey to gather feedback on the guide. The survey closes on May 1, 2022.

The Ontario Association of Architects (OAA) has announced their 2022 Design Excellence Awards Finalists. DTAH is proud to share that the Tommy Thompson Park Entrance Pavilion was one of the 17 Finalists announced.

Located in Toronto’s Port Lands Precinct, Tommy Thompson Park is a unique urban wilderness minutes from downtown, located on a manmade peninsula known as the Leslie Street Spit. The Tommy Thompson Park Entrance Pavilion establishes a new front door to the park that is welcoming, engaging, and ecologically sensitive to its context. Serving as a centre for discovery and education, the entrance pavilion is designed as a simple, yet elegant form split in two halves, covered by an expansive cantilevered roof. One half of the structure houses public accessible washrooms, while the other contains administrative spaces that support on-site educational programming.

DTAH is excited to have co-authored the City of Toronto’s first ever Green Infrastructure Design and Construction Standards! Developed along with our long-time friends and engineering partners at Arup, the standards address significant issues related to stormwater quality and quantity, and climate change.

Green infrastructure is defined by the City of Toronto’s Official Plan as natural and human-made elements that provide ecological and hydrological functions and processes. Green infrastructure is a cost-effective, resilient approach to managing the impact of wet weather events that provides social, economic, and environmental benefits, by capturing and storing precipitation where it falls.

Examples of green infrastructure include street trees, bioretention planters, rain gardens and permeable pavements that work alongside the City’s traditional infrastructure. Traditional streets are designed to direct stormwater into storm sewer systems, but Green Streets are designed to capture rainwater for plants and trees to grow. Green Streets also act as a natural filter to clean stormwater before it makes its way into local waterways.

In addition to mitigating and preventing the impacts of climate change, such as floods and droughts, green infrastructure also lowers greenhouse gas emissions, improves air quality, increases tree canopy and shade, increases biodiversity and habitats for animals, and enhances public realm aesthetics.

The revitalization and expansion of St. Andrew’s Playground Park at 450 Adelaide St. West is now complete.

DTAH led the design, which included updated amenities and improved programming, and better connectivity to the surrounding area. The expanded park now also includes the former parking lot on the western edge of the site.

The park features mature trees, flower gardens, seating with Catenary lights, picnic tables, a playground, passive areas with lawn, and a dog off-leash area, providing valuable greenspace in Toronto’s Fashion District. The project acts as an important next step in implementing the City of Toronto’s new Downtown Plan and its accompanying Parks and Public Realm Plan.

The historically significant park was the site of the City’s first public playground for children, located next to the site of the former St. Andrew’s Market, a public market hall which was built in 1850 and demolished in 1932.
