Former North York By-law 7625: How Non-Conforming Status Affects Your Addition

Properties in North York that were built under former By-law 7625 and have not been rezoned to 569-2013 operate under different setback baselines, different expansion allowances for non-conforming structures, and different variance calculation methods than properties governed by the city-wide zoning by-law. This means two identical houses on the same street can face completely different permit pathways for the same addition, depending on which by-law applies. If your property was developed before 569-2013 came into effect and your zoning still references 7625 provisions, your existing setbacks may be legally conforming under the old by-law but non-conforming under the new one, or vice versa. The practical impact is significant: what triggers a Committee of Adjustment hearing under one regime might be as-of-right under the other.

Why Two By-laws Still Govern North York Properties

When Toronto amalgamated in 1998, each former municipality brought its own zoning by-law. North York operated under By-law 7625, which had been in place since the 1980s and reflected development patterns specific to that area. When the city-wide By-law 569-2013 was adopted, it was intended to harmonize zoning across all former municipalities. However, the transition was not instantaneous. Many properties retained their 7625 zoning either because they were subject to site-specific exceptions, because appeals delayed the transition, or because certain zones were not yet harmonized.

The result is a patchwork. Some North York properties are fully governed by 569-2013. Others remain under 7625 with all its original provisions. Still others have hybrid situations where 569-2013 applies but with site-specific exceptions that reference 7625 standards. When you apply for a building permit for an addition, the zoning examiner must first determine which by-law applies to your lot. This determination drives everything that follows.

How Non-Conforming Status Differs Between the Two By-laws

A building is legally non-conforming when it was lawfully constructed under the rules in effect at the time but no longer complies with current zoning standards. Both by-laws recognize this concept, but they treat it differently in ways that matter for additions.

Setback Baselines Under By-law 7625

By-law 7625 established rear yard setbacks, side yard setbacks, and lot coverage limits that often differed from what 569-2013 now requires. For example, certain residential zones under 7625 permitted smaller side yard setbacks than the equivalent zones under 569-2013. If your house was built with a side yard setback that complied with 7625 but falls short of 569-2013 requirements, your status depends entirely on which by-law still governs your property. Under 7625, that setback remains conforming. Under 569-2013, it becomes a legal non-conformity that constrains what you can do.

Expansion Rules for Non-Conforming Buildings

Both by-laws allow some expansion of non-conforming buildings, but the thresholds differ. By-law 569-2013 generally permits enlargement of a non-conforming building provided the enlargement itself complies with current zoning standards, even if the existing building does not. By-law 7625 had its own expansion provisions that in some cases were more permissive and in others more restrictive. The specific zone designation under 7625 matters enormously here.

What we see on applications is confusion about which standard applies. A homeowner assumes their property falls under 569-2013 because that is the current city-wide by-law, prepares drawings accordingly, and then learns during zoning review that their lot is still governed by 7625. The setback calculations must be redone, and the variance analysis changes completely.

“

We have seen additions that would have been as-of-right under 7625 require variances under 569-2013, and we have seen the reverse. The by-law determination is not a formality. It is the foundation of your entire permit strategy.

Determining Which By-law Governs Your Property

The City of Toronto's interactive zoning map will show you the current zoning designation for your property, but it does not always make clear whether 7625 provisions still apply. For properties in North York, you need to check whether your lot has been fully transitioned to 569-2013 or whether exceptions, deferrals, or site-specific provisions keep 7625 in play.

• Check the zoning map for any site-specific exceptions referencing former by-laws
• Review the property's zoning certificate or any previous permit files
• Contact Toronto Building's zoning inquiry desk with your property address
• Look for references to 7625 zone designations in your title documents or previous surveys

At PermitsHub, we handle North York addition projects regularly and always verify the governing by-law before starting drawings. This step prevents wasted effort and ensures the variance strategy, if any is needed, is built on accurate foundations.

Variance Thresholds: Same Deficiency, Different Outcomes

When a proposed addition cannot comply with zoning standards, you need a variance from the Committee of Adjustment. The variance application must quantify the deficiency, which is where the by-law determination becomes critical.

Consider a property with a rear yard setback of 7 metres. Under By-law 7625, the required rear yard setback for that zone might have been 7.5 metres, making the existing condition a minor non-conformity. Under By-law 569-2013, the required rear yard setback for the equivalent zone might be 7 metres, making the existing condition fully conforming. If you want to build an addition that extends into the rear yard, the variance calculation depends entirely on which baseline applies.

How This Affects Your Addition Design

The practical impact is that your addition design may need to be adjusted based on the governing by-law. If 7625 applies and has more permissive standards, you may be able to build a larger addition as-of-right. If 569-2013 applies and imposes stricter standards, the same addition might require one or more variances. The Committee of Adjustment evaluates variances against four tests, and the size of the deficiency matters to how those tests are applied.

We often see cases where a homeowner could avoid a variance entirely by making modest adjustments to the addition footprint, but only if they know the correct setback requirement from the start. Getting this wrong means either leaving space on the table or triggering an unnecessary hearing.

Site-Specific Exceptions and Hybrid Situations

Some North York properties exist in a middle ground where 569-2013 nominally applies but with site-specific exceptions that preserve certain 7625 standards. These exceptions were created during the harmonization process to address properties with unique circumstances or to resolve appeals. They appear in the exceptions schedules to 569-2013 and reference the former by-law provisions that continue to apply.

Reading these exceptions requires careful attention. The exception might preserve 7625 setback standards but adopt 569-2013 lot coverage limits. Or it might preserve 7625 height limits but apply 569-2013 angular plane requirements. Each combination creates a different regulatory environment for your addition.

• Site-specific exceptions are listed by property address in the 569-2013 schedules
• The exception text specifies which 7625 provisions remain in effect
• Some exceptions have sunset clauses or conditions that may have lapsed
• Heritage overlays and conservation authority regulations apply regardless of which zoning by-law governs

The Permit Process When 7625 Applies

When your property is governed by By-law 7625, the permit application process follows the same general steps as any Toronto permit, but the zoning review references the former by-law standards. The examiner will measure your existing building against 7625 requirements, determine any non-conformities, and evaluate your proposed addition against 7625 expansion rules.

Your drawings must clearly indicate the applicable by-law and the specific zone designation. This is not optional. If the drawings reference 569-2013 standards when 7625 applies, the application will be returned for correction. This adds weeks to your timeline and may require redesign if the setback calculations change.

Documentation You Need

For properties under 7625, you should gather documentation establishing when your house was built and under what zoning. Previous building permits, original surveys, and zoning certificates all help establish the legal status of your existing building. If your house predates modern permit records, you may need to rely on property tax records or other municipal archives to establish the construction date.

This documentation matters because the non-conforming status of your existing building affects what expansion is permitted. A building that was legally constructed under 7625 has different rights than a building that was constructed in violation of 7625 and later tolerated.

Common Scenarios We See on North York Addition Projects

After handling hundreds of permit applications across the GTA, including many in North York, certain patterns emerge. These scenarios illustrate how the by-law determination affects real projects.

The first common scenario involves homes built in the 1970s and 1980s with side yard setbacks that complied with 7625 but fall short of 569-2013 requirements. Homeowners want to add a second storey or extend the rear of the house. Under 7625, the existing side yard setback is conforming, so the addition can maintain that setback. Under 569-2013, the existing setback is non-conforming, and the addition might need to be set back further or require a variance.

The second common scenario involves lot coverage. By-law 7625 calculated lot coverage differently than 569-2013 in some zones, particularly regarding what structures counted toward the limit. A property that is under the lot coverage limit under 7625 might exceed it under 569-2013 calculations, or vice versa. This affects how large an addition you can build without a variance.

“

The worst outcome is designing an addition based on the wrong by-law and discovering the error during permit review. By then, you have paid for drawings that need significant revision and lost months of timeline.

Working With PermitsHub on North York Additions

Our North York experience means we know to check the by-law determination before putting pencil to paper. We verify whether your property falls under 7625, 569-2013, or a hybrid situation with site-specific exceptions. This verification shapes the entire project strategy, from initial design through permit submission.

When a variance is needed, we prepare drawings that clearly document the existing conditions, the applicable standards, and the specific relief requested. The Committee of Adjustment process is more predictable when the application is well-documented and the variance request is properly framed against the correct by-law.
