Multi-Unit Conversions Hamilton | Ontario Housing Summit Insights

Bringing Collaboration Back to the Housing Conversation

Multi-unit conversion opportunities in Hamilton took center stage as Gateway Group President Charles Wah joined ministers, municipal leaders, and housing experts at the Central Ontario Housing Summit 2025. The collaborative event, hosted by WEHBA and OHBA, brought together industry leaders focused on solving Ontario’s housing crisis through triplex conversions, fourplex development, and infill housing solutions.

Held at The Pearle in Burlington, the event gathered voices from across the public and private sectors. City planners, industry innovators, and policy makers all shared one goal: building attainable, family-sized housing for Ontario’s future.

A Clear Message: Collaboration Builds Communities

One key takeaway echoed throughout the summit:

“We can’t solve Ontario’s housing crisis in silos.”

Dr. Mike Moffatt from the Missing Middle Institute shared some eye-opening data. Ontario has a severe shortage of 3+ bedroom, ground-oriented homes. These are exactly the type of homes that attract families and drive long-term community stability.

Here’s what the numbers show:

• Cities building these homes are retaining families
• Cities that don’t are losing population to other provinces
• The gap keeps widening, and families are paying the price

This aligns perfectly with what we do at Gateway Group in Hamilton, Burlington, and across Southern Ontario. The data confirms what we’re seeing on the ground: investors are increasingly looking at triplex and fourplex projects as a way to address Hamilton’s housing shortage while generating solid returns.

Gateway Group’s Commitment to Real Housing Solutions

At Gateway, we believe the path forward isn’t just about building more homes. It’s about building the right kind of homes through multi-unit conversions in Hamilton and the Greater Toronto Area.

Here’s what we focus on:

✅ Multi-unit conversions (duplex, triplex, fourplex) in established Hamilton neighborhoods
✅ Infill development that brings new life to underutilized properties
✅ Legal basement suites and garden suites for multi-generational families
✅ Attainable, family-sized housing across Southern Ontario

We help Hamilton and Burlington investors transform underutilized properties into valuable multi-unit homes. This approach lets families stay in the communities they love instead of being pushed to the suburbs.

What This Means for Investors

Multi-unit, family-sized housing isn’t just good for communities. It’s also a high-demand, future-proof investment in Ontario’s housing market.

At Gateway Group, we help Hamilton property owners and investors tap into this opportunity through triplex and fourplex conversions, infill builds, and legal basement suites. All designed to maximize ROI while addressing the housing shortage.

Your Hamilton property could be the solution Ontario needs and a profitable investment for your portfolio.

Our Hamilton clients typically see 12-18% annual ROI on multi-unit conversions. Many generate monthly cash flows of $3,000 to $6,000+ while increasing their property values by $200,000 to $400,000.

Leadership That Drives Collaboration

Charles Wah serves as WEHBA’s 2nd Vice Chair and Chair of the Missing Middle and Infill Subcommittee. In these roles, he continues to bridge the gap between policymakers, municipalities, and builders across Hamilton and Ontario. His work turns collaboration into concrete progress.

The summit reinforced what we’ve always believed at Gateway:

💬 Real change happens when industry and government work together, not apart.

Charles’s leadership at WEHBA and his contributions to the Infill Development Bible have positioned Gateway Group as Hamilton’s go-to authority on multi-unit conversions and missing middle housing solutions.
