20. Four Statutory Tests Analysis
What It Is
A detailed analysis of whether a proposed minor variance satisfies the four statutory tests required under Section 45(1) of the Planning Act. This is the most critical legal document for any minor variance application.
Why It Matters
- Every minor variance in Ontario must pass all four tests — failure on any one test means refusal
- Committee of Adjustment members use these tests as their decision framework
- OLT applies these tests on appeal
- This is the single most important skill for Ontario planning AI
Governing Law
- Planning Act, R.S.O. 1990, c. P.13, s. 45(1)
The four tests are:
The Committee of Adjustment may authorize a minor variance
from the provisions of the by-law if, in the opinion of the
Committee, the variance:
TEST 1: Maintains the general intent and purpose of the
Official Plan
TEST 2: Maintains the general intent and purpose of the
Zoning By-law
TEST 3: Is desirable for the appropriate development or
use of the land, building or structure
TEST 4: Is minor in nature
How to Build Each Test
TEST 1: General Intent and Purpose of the Official Plan
PURPOSE: Demonstrate that the variance is consistent with
the broader policy objectives of the Official Plan, even if
it deviates from a specific zoning standard.
APPROACH:
1. Identify the Official Plan land use designation
(e.g., "Neighbourhoods", "Mixed Use Areas", "Apartment
Neighbourhoods", etc.)
2. Quote the relevant OP policies for that designation
Example (Toronto — Neighbourhoods):
- Section 4.1.5: "Development in established Neighbourhoods
will respect and reinforce the existing physical character
of each geographic neighbourhood..."
- Policy criteria: lot size, setbacks, heights, building
types, prevailing conditions
3. For each relevant policy, explain how the variance
is consistent:
- "The proposed height of 12.5m maintains the general intent
of the Neighbourhoods designation because the OP does not
prescribe a specific maximum height for Neighbourhoods but
rather requires development to respect prevailing heights.
The prevailing height on this block ranges from 10m to 13m,
and the proposed height falls within this range."
4. Address growth and housing policies:
- PPS 2024 requires efficient use of land and infrastructure
- OP housing policies encourage gentle intensification
- OP complete communities policies support additional units
COMMON MISTAKES TO AVOID:
- Do NOT simply say "the OP permits residential use, so the
variance maintains the OP intent." This is insufficient.
- DO connect the specific variance to specific policies.
- DO address the spirit of the policy, not just the letter.
TEST 2: General Intent and Purpose of the Zoning By-law
PURPOSE: Demonstrate that even though the proposal doesn't
meet the specific numerical standard, it achieves the
OBJECTIVE that the standard was designed to achieve.
APPROACH:
1. For each variance, identify WHY the zoning standard exists.
Each standard has an underlying planning purpose:
| Standard | Underlying Purpose |
|----------|-------------------|
| Maximum height | Limit shadow, maintain neighbourhood scale, protect views |
| Minimum front setback | Maintain consistent streetscape, allow landscaping |
| Minimum rear setback | Protect rear yard amenity, provide light and privacy |
| Minimum side setback | Fire separation, drainage, light penetration, access |
| Maximum lot coverage | Ensure permeable surface, limit bulk |
| Maximum FSI/density | Control population density, manage infrastructure |
| Minimum parking | Ensure adequate parking supply (but note: PPS 2024 and Bill 185 now support reduced parking) |
| Minimum landscaping | Stormwater management, aesthetics, urban canopy |
| Angular plane | Protect light and sky view for neighbours |
2. Explain how the variance still achieves that purpose:
Example: "The intent of the 7.5m rear yard setback is to
protect the amenity of the rear yard and ensure adequate
light and privacy for neighbouring properties. The proposed
5.0m rear yard setback maintains this intent because:
(a) the rear portion of the building is single-storey,
minimizing shadow and overlook;
(b) existing mature vegetation along the rear lot line
provides screening;
(c) the proposed rear yard (5.0m × 12m lot width = 60 sq m)
still provides a functional outdoor amenity area."
3. Use quantitative evidence where possible:
- Shadow diagrams showing limited impact
- Angular plane compliance despite setback reduction
- Lot coverage still reasonable
- Comparison to neighbouring properties
COMMON MISTAKES TO AVOID:
- Do NOT say "the variance is small, so it maintains the intent."
Size is Test 4, not Test 2.
- DO explain the actual purpose of the specific standard.
TEST 3: Desirable for the Appropriate Development of the Land
PURPOSE: Demonstrate that the variance results in a development
that is appropriate for this specific property and its context.
APPROACH:
1. Describe the specific characteristics of the property that
make the variance appropriate:
- Lot shape (irregular lots may justify setback variances)
- Lot size (undersized lots may justify coverage/density variances)
- Topography (sloped lots may justify height variances)
- Existing conditions (mature trees, existing structures)
- Neighbourhood context (what exists on adjacent properties)
2. Demonstrate compatibility with surrounding development:
- "The proposed addition is consistent with the scale and
character of recent development on this street."
- Reference specific comparable properties
- Note if neighbours have similar non-compliances
(many older homes don't comply with current zoning)
3. Address any negative impacts and explain why they are
acceptable:
- Shadow: "Shadow studies demonstrate that additional shadow
falls primarily on the subject property's own yard."
- Overlook: "No windows are proposed on the side elevation
facing the neighbour."
- Traffic/parking: "The proposal provides adequate parking
for the intended use."
4. Identify positive benefits:
- Additional housing in an area well-served by transit
- Improved built form compared to existing conditions
- Enhanced streetscape
- Better utilization of serviced urban land
COMMON MISTAKES TO AVOID:
- Do NOT focus only on the applicant's desire — the test asks
about the LAND, not the owner.
- DO focus on site-specific conditions and context.
TEST 4: Minor in Nature
PURPOSE: Demonstrate that the variance is quantitatively
and qualitatively minor — the impacts are small.
APPROACH:
1. QUANTITATIVE assessment:
- Calculate percentage departure from the standard
- Compare to precedent decisions
- Note: There is no fixed percentage threshold in law.
However, in practice:
- <10% departure: generally considered minor
- 10-25%: often minor, depends on context
- >25%: harder to justify as minor, but not impossible
- Some variances are measured in absolute terms
(e.g., 0.3m side setback reduction is very different
on a narrow lot vs. a wide lot)
2. QUALITATIVE assessment (impact-based):
- "Minor" refers to the IMPACT, not just the number
- A 50% height increase on a 6m garage (to 9m) may be
minor in impact if it's a single-storey area
- A 10% height increase on a 30-storey tower (to 33 storeys)
may NOT be minor in impact
Assess:
- Shadow impact: additional shadow in hours/area
- Privacy impact: new overlook situations
- Traffic impact: additional vehicle movements
- Parking impact: adequacy of proposed parking
- Streetscape impact: visual change from public realm
- Servicing impact: infrastructure capacity
3. Precedent comparison:
- Reference approved variances of similar magnitude
- "This variance is consistent with or smaller than
variances routinely approved by this Committee."
4. Cumulative assessment:
- When multiple variances are requested, assess whether
the CUMULATIVE effect is minor
- Individual variances may each be minor, but together
may represent a significant departure
- Address this directly: "While [X] variances are requested,
they collectively represent a modest intensification
that is appropriate for this context."
COMMON MISTAKES TO AVOID:
- Do NOT rely solely on percentage — a 5% increase in
permitted units from 100 to 105 is very different from
a 5% reduction in a 1.2m side setback to 1.14m.
- DO assess actual impact on the ground.
- DO address cumulative effect of all variances together.
