The City of Mississauga is reviewing its urban design requirements in an effort to streamline housing approvals and support the construction of more affordable homes.
At a recent Planning and Development Committee meeting, staff outlined the City’s Urban Design Program Review and recommended several immediate changes aimed at unlocking additional housing in urban areas.
Urban design guidelines shape public spaces, streets, buildings and landscapes. In Mississauga, developers must follow a range of requirements, including wind and shadow studies. The review will include a comprehensive assessment of the City’s urban design guidelines, as well as related Official Plan policies and zoning bylaw regulations.
“Housing supply and affordability remain key issues facing Mississauga residents,” Andrew Whittemore, commissioner of planning and building, said in a statement. “Reviewing our urban design program will help remove housing barriers without compromising the standards that make our communities great places to live.
“Cities are not static. As planners, we must be ready to respond to changing demographics, infrastructure needs and economic conditions.”
The goal is to remove unnecessary barriers to housing while continuing to promote healthy, well-designed and vibrant communities.
The review also responds to recommendations from the Mayor’s Housing Task Force, a group of more than 30 representatives from Ontario’s private and non-profit building and development sector. The task force found that some urban design requirements have increased costs and slowed housing construction without delivering meaningful community benefits.
In late 2024, Mississauga introduced two urban apartment zones in the zoning by-law. The regulations are designed to help speed up development approvals for apartments in urban areas. Staff are now proposing updates to the City’s urban design requirements for these areas. Recommendations include:
Replacing ‘angular plane’ requirements with simplified setbacks: Many communities across Canada are revisiting policies that require buildings to ‘step back’ as they increase in height. This requirement removes floorspace that could be used for housing – without providing a meaningful impact on the quality of life in these urban communities. It also drives up construction costs by requiring heavier structures, transfer systems and inefficient layouts.
Reducing minimum tower distances: Setting a minimum distance between towers helps protect privacy, sky views and mitigates wind impacts. Staff recommend reducing the required distance from 30 to 25 metres which is more typical for urban areas. This helps buildings fit more naturally on a site, supports practical building layouts and avoids leaving portions of a site underused – especially on smaller or irregularly shaped properties.
Other urban design-related recommendations include providing more flexibility for amenity areas for residents, ground-floor windows and street-level building entrances.
Staff also recommend reducing the minimum distance between residential towers from 30 metres to 25 metres, which they said is more typical in urban settings. The change is intended to allow buildings to fit more naturally on sites, support practical layouts and avoid leaving portions of smaller or irregular properties underused.
Additional recommendations include providing more flexibility for indoor and outdoor amenity areas, ground-floor windows and street-level entrances.
As the review continues, City staff will consult with developers and community members before bringing proposed updates to Urban Design Guidelines and Design Reference Notes to council for endorsement. Proposed zoning changes for urban apartment zones and amenity areas are expected to go to council for approval in April, subject to further comments received before the meeting.
