Toronto has expanded permissions for missing middle housing, but the results remain uneven across the city. This article looks at where new multiplexes and laneway suites are being built, why some neighbourhoods are contributing less, and what needs to change for policy intent to become real-world housing outcomes.

Missing middle housing is gaining momentum across Toronto, but evaluating feasibility remains complex and time-consuming. Through interviews with planners, architects, developers, and consultants, Ratio.City identified key challenges and built new tools to help practitioners assess multiplex and townhouse opportunities faster and with greater confidence.

Toronto's housing crisis may have a solution hiding in plain sight. With new as-of-right rules allowing up to four units on most residential lots, the city's existing housing stock has become a faster, cheaper, and greener path to new supply. Felicity Xiao explores how internal conversion of large homes can deliver missing middle housing today, and how Ratio.City helps developers and homeowners find the right sites to convert.

Making data 'open' is no longer the challenge. Making it usable is. Drawing on conversations with planning professionals and months of hands-on work at Ratio.City, this piece explores why access alone falls short, how weak data foundations limit even the most advanced tools, and what municipalities need to get right next.

Can AI really extract planning data from zoning by-laws accurately? In part 1 of this series, Jocelyn Tang explores the AI concepts, model types, and trade-offs that matter when working with legal planning text.

Gentle density is becoming a bigger part of how cities grow, but the path from policy to real projects is still complex. In this piece, Erin Morrow explores who is actually building the missing middle, why these projects are often harder than they appear, and what better tools could do to help small-scale development move forward.

Multidisciplinary Urban Capstone Project (MUCP) students at the University of Toronto's School of Cities reimagined long-term care in Toronto’s downtown core by combining podium-level LTC with residential towers above. Using Ratio.City for contextual analysis and massing, the team demonstrated how modest policy adjustments could unlock 9,000 much-needed beds while increasing housing and jobs near transit.

Finding hidden development density is becoming one of the most valuable skills in Canadian real estate and urban planning. As cities shift away from greenfield expansion and toward intensification, opportunities increasingly exist within underutilized industrial and commercial land located near transit corridors. Using London, Ontario as a case study, this article shows how municipal zoning, federal Housing Accelerator Fund policies, and provincial Protected Major Transit Station Areas intersect to unlock new development potential. Learn how Ratio.City helps planners, developers, and land acquisition teams layer policy, transit, and land-use data to identify high-value density opportunities faster and with less risk.
