Appendix A: Ontario Regulation Quick Reference
O. Reg. 299/19 — Additional Residential Units
Key provisions:
- Permits up to 2 additional residential units as-of-right
on lots zoned for residential use
- One unit may be in the primary dwelling
(e.g., basement apartment)
- One unit may be in an accessory building
(e.g., laneway suite, garden suite)
- Municipal zoning cannot prohibit these units if the
lot is zoned residential
- Units must comply with OBC, fire code, and applicable
municipal standards for size, parking, etc.
- Municipality CAN set standards for ARUs (setbacks, height,
etc.) but CANNOT prohibit them entirely
- Servicing: lot must be on municipal water and sewer
for accessory building unit (or demonstrate adequate
private services)
O. Reg. 462/24 — As-of-Right Fourplexes
Key provisions (verify current text — regulation is new):
- Permits up to 4 residential units on lots in settlement
areas zoned for residential use
- Applies in municipalities above certain population thresholds
- Overrides municipal zoning to the extent of the regulation
- Municipality cannot require:
- More than 1 parking space per unit (or 0 within 800m
of higher-order transit — check exact provision)
- Application fees for these units
- Units must comply with OBC
- Maximum height and other standards may be specified
in the regulation
- Does NOT override Official Plan designations that
prohibit residential use (e.g., employment lands)
Bill 185 (2024) Key Planning Changes
- Third-party appeals: Only applicant, municipality, or
specified public bodies can appeal minor variance and
consent decisions to OLT
- No more neighbour appeals for minor variances
- Parking: Province removed authority for municipalities
to require minimum parking near major transit stations
(within 800m of higher-order transit station)
- Site plan control: Already limited by Bill 23 to exclude
≤10 residential units; Bill 185 continues this direction
- Community benefits: CBC framework continues
- OLT: Enhanced case management and mediation
Bill 23 (2022) Key Planning Changes Still in Effect
- Site plan control: Exempt for ≤10 residential units
- Conservation authorities: Scope limited to natural hazards
(flooding, erosion); no longer comment on planning policy
- Heritage: 2-year limit on listing properties on heritage
register without designation; limited interior designation
- Parkland dedication: Alternative rate caps
- Development charges: Phased-in DC for certain building types
(5-year phase-in for purpose-built rental, affordable,
institutional, non-profit)
- Section 37: Replaced with Community Benefits Charges
(applicable to ≥10 units and ≥5 storeys)

Appendix D: Key OLT Case Law Themes for AI Training
When building the AI's ability to analyze and cite precedent,
train on these common OLT themes:
1. MINOR VARIANCE — HEIGHT
Key principle: Height is evaluated relative to neighbouring
heights, not in a vacuum. A 15% height variance may be minor
on a street with varied heights but not minor where all
houses are uniform.
2. MINOR VARIANCE — FSI/DENSITY
Key principle: FSI is a proxy for building bulk. The actual
impact matters more than the percentage increase. Built form
and compatibility analysis is critical.
3. MINOR VARIANCE — SETBACKS
Key principle: Setback variances are evaluated based on
impact on adjacent properties — privacy, overlook, light
access, and streetscape consistency.
4. MINOR VARIANCE — PARKING
Key principle: Post-Bill 185 and PPS 2024, reduced parking
is increasingly supported near transit. TDM measures
strengthen the case. Car ownership data is relevant.
5. FOUR TESTS — GENERAL APPROACH
Key principle: All four tests must be met. The tests are
not a checklist but an integrated assessment. The OLT
weighs all evidence and makes its own determination —
it does not simply review the Committee's decision.
6. GOOD PLANNING
Key principle: For ZBAs, the OLT asks whether the proposal
represents "good planning." This requires demonstrating
conformity with the policy framework AND that the proposal
is appropriate for the site.
7. PLANNING EVIDENCE
Key principle: OLT gives the most weight to qualified
planning opinion evidence. Lay testimony is considered
but does not outweigh professional opinion unless the
professional evidence is weak.
