Committee of Adjustment: Minor Variances for Toronto Suites | RCSQ

In a perfect world, every laneway or garden suite would be built "as-of-right," meaning it fits perfectly within the City of Toronto’s pre-defined zoning bylaws. However, Toronto lots are rarely perfect. Whether it’s an oddly shaped property, a massive protected tree, or a desire for a slightly higher ceiling, many projects require a Minor Variance.

When you ask for a variance, your project is sent to the Committee of Adjustment (CofA). This is a public hearing where a panel of citizens decides if your request is "minor" enough to be allowed. At RCSQ, we’ve seen that success at the CofA isn't about luck—it’s about meeting the "Four Tests" of the Planning Act.

The Four Tests of a Minor Variance

To approve your application, the Committee must be convinced of the following:

1. Is the variance minor? This is subjective. A 10cm height increase is usually considered minor; adding an entire extra floor is not. The Committee looks at the impact of the change, not just the number. Does the extra height block a neighbour's sunlight or overlook their bedroom window?

2. Is it desirable for the appropriate development of the land? Does the change make sense for the neighbourhood? If you are asking for a variance to save a 100-year-old oak tree by shifting the building’s footprint, the Committee often sees this as a "desirable" trade-off.

3. Does it maintain the general intent of the Official Plan? The City’s Official Plan wants to see more "gentle density" in neighbourhoods. If your variance helps create a high-quality housing unit without disrupting the character of the street, you are aligned with the City’s long-term goals.

4. Does it maintain the general intent of the Zoning Bylaw? Zoning bylaws exist to ensure safety, privacy, and adequate green space. If your variance doesn't compromise these core principles—for example, if you are asking for a smaller setback but still providing plenty of drainage—you are more likely to get a "yes."

The Importance of Neighbour Support

The Committee of Adjustment is a public forum. Your neighbours will be notified of your application and invited to speak. A single angry neighbour can turn a simple 15-minute hearing into a months-long ordeal.

The RCSQ Strategy: We encourage proactive "neighbour relations." Showing your neighbours your plans early, explaining how you’ve mitigated privacy concerns, and getting letters of support can make the Committee’s decision much easier.

The Cost of the CofA

It is important to remember that going to the Committee of Adjustment adds both time (typically 3 to 5 months) and money (application fees and professional representation) to your project. At RCSQ, we always analyze whether a design can be adjusted to fit "as-of-right" before recommending the CofA route.

Expert Representation

If a variance is necessary to unlock the full potential of your lot, you need a team that knows how to speak the language of the Planning Act. We work with planners and designers who specialize in presenting clear, evidence-based arguments to the Committee to get your project approved.
