Ontario Housing Projects Are Approved — So Why Can’t They Build?

Ontario housing development is facing a new challenge. Even projects that have cleared zoning and planning approvals can still be prevented from moving forward because of something far less visible: water and sewer capacity.

The problem is what happens underground.

Across Ontario, housing projects that have already cleared major planning hurdles are being delayed because municipalities simply don’t have enough water and sewer capacity to service them. In some areas, existing trunk lines are undersized. In others, the infrastructure required to support new development doesn’t exist yet.

That means land can effectively be ready for development on paper while remaining unable to move forward with construction.

Water and Sewer Capacity Is Becoming a Major Development Bottleneck

According to a recent STOREYS report, industry leaders gathered at a ULI Toronto event to discuss how servicing constraints are affecting Ontario development.

For developers, these delays can be incredibly expensive.

Projects may sit for years waiting for major municipal infrastructure to arrive while developers continue carrying the land and absorbing financing and other costs.

STOREYS highlighted one York Region example involving a 140-acre master-planned community designed for approximately 3,000 homes. The project has reportedly been stalled for more than a decade while waiting for a servicing solution.

When infrastructure takes that long to arrive, it doesn’t just affect developers. Delays can ultimately affect when new housing supply reaches the market and how much it costs to deliver.

According to a recent report from STOREYS, industry leaders gathered at a ULI Toronto event to discuss how servicing constraints are affecting Ontario housing development. The discussion highlighted how limited water and wastewater infrastructure can leave otherwise development-ready projects waiting years for servicing.

Could Modular Infrastructure Help?

One potential solution being explored is decentralized or modular water and wastewater treatment.

Instead of waiting for municipalities to construct enormous centralized infrastructure projects, smaller treatment systems can potentially be installed closer to individual developments or groups of developments.

These systems can also be expanded in phases as communities grow.

That scalability could be particularly valuable for developments that aren’t large enough to justify major municipal infrastructure but are too dense to rely on traditional individual septic systems.

Municipal Service Corporations Could Play a Bigger Role

Another option receiving attention is the use of Municipal Service Corporations, or MSCs.

These organizations can provide an alternative structure for operating communal water and wastewater infrastructure while maintaining municipal ownership.

Recent legislative changes in Ontario are creating additional opportunities for municipalities and developers to explore these servicing models.

These infrastructure constraints are becoming an increasingly important consideration for Ontario housing development as communities plan for continued growth.

For smaller communities and areas outside major urban centres, communal servicing could help bridge the gap between individual private systems and large-scale municipal infrastructure.

Ontario’s Housing Challenge Goes Beyond Approvals

Ontario’s housing shortage is often framed as an approvals problem.

Approvals certainly matter, but approving more homes doesn’t automatically mean those homes can be built.

Development also requires roads, electricity, water and wastewater infrastructure capable of supporting thousands of additional residents.

If that infrastructure can’t keep pace with planned growth, projects can remain stalled regardless of how quickly zoning or planning approvals are granted.

Finding new servicing solutions could therefore play a major role in unlocking future Ontario housing development and bringing more homes to market.

What This Means for Ontario Real Estate

The conversation around Ontario housing supply is changing.

Getting projects approved faster is only one piece of the puzzle. Municipalities and developers also need viable ways to service those projects once approvals are in place.

Modular treatment systems, communal servicing and Municipal Service Corporations may become increasingly important tools for unlocking land that would otherwise remain undeveloped.

For buyers, sellers, investors and homeowners, it’s another reminder that housing supply is influenced by far more than interest rates and market demand.

Sometimes, one of the biggest obstacles to building more homes is infrastructure most people never see.
