Short-Term Rental Regulation — Playbook
Toronto limits Airbnb-style rentals to a host's own home — how much that rule has actually returned units to renters.

The honest bottom line
Toronto's STR program is active and has teeth — the enforcement numbers are real. What isn't yet established is whether it's actually preserving the housing stock it exists to protect, because the City has never gone back and re-measured the market the way it was measured once, before the bylaw existed. Week one starts there: fund the study, formalize the scorecard, and only then decide whether the bylaw itself needs to change.

RC-str-01 — Commission an Independent Post-2024-Amendment STR Market Study
Card id: RC-str-01 · Issue: short-term-rental-regulation · Backgrounder: our research file for that page §"The pre-bylaw academic baseline" / §"Open questions / data gaps" · Trust: New load-bearing findings
Problem
The only rigorous, independent (non-City, non-platform) empirical study of Toronto's STR market — the 2019 UPGo/McGill report — predates the bylaw's actual implementation and the City's own April 2024 bylaw amendments. The City's 2024 Auditor General audit provides detailed program-activity figures (registrations, complaints, revocations) but does not independently measure current market-wide housing loss or actual compliance rate the way the 2019 study did [backgrounder, "Key tensions / tradeoffs"]. No source in this page’s evidence base can currently answer whether the bylaw, as amended and enforced through 2025–2026, has measurably reduced STR-driven housing loss from the 2019 baseline of 5,557 units.
Action
The City commissions (or funds an academic partner, such as UPGo/McGill itself, to conduct) an independent follow-up study replicating the 2019 methodology against current data, to produce a directly comparable current housing-loss and compliance estimate.
Jurisdiction split
- City does: commission or fund the study; provide any City-held data (registration records, complaint records) an independent researcher would need, subject to privacy constraints.
- City demands of Province: none.
- City demands of Feds: none, though federal research-funding bodies (e.g., SSHRC, which funded the original UPGo study per its own acknowledgments) are a plausible funding partner, not a demand.
Cost
Order of magnitude: low, non-capital — a research grant/contract comparable in scale to an academic study, not a capital or program-operating expenditure. Named comparator: the original 2019 UPGo study was funded through a single SSHRC Insight Grant (#435-2019-0720), per that report's own acknowledgments [backgrounder, source quote] — a plausible order-of-magnitude anchor for a comparable follow-up, though this card does not know the original grant's dollar value and does not invent one.
Funding path
A City this library's internal records budget line, or a partnership grant application to a federal research funder (SSHRC), following the precedent of how the original study was funded.
Who benefits, and how
Toronto residents and policymakers broadly, via a genuine, independently-verified answer to whether the bylaw is working — replacing the current situation where the City's own program-activity data (registrations, revocations) cannot by itself answer the housing-loss question the bylaw exists to address.
Who bears the cost, and how
City taxpayers (or a research-funder's general grant pool), via a modest one-time or periodic research expenditure.
Financial ROI
Not applicable in the conventional sense — this is a this library's internal records action, not a fiscal one. Its value is informational: it would allow future policy (including other cards in this page) to be evaluated against real current data rather than a 2019 baseline or the City's own activity metrics alone.
Economic ROI
Not yet estimable — a research study has no direct economic effect; its value is in informing subsequent policy decisions whose economic effects are not yet known. No comparator applicable. Confidence: low, in the sense that this dimension is largely inapplicable to a research-commissioning action.
Social ROI
Directional only: better information about whether STR regulation is achieving its stated housing-preservation goal is a precondition for any well-targeted policy response to the housing-loss problem the 2019 UPGo study documented (5,557 units, doubling the effective rental vacancy rate if returned to long-term use) — but this card does not claim the study itself would return any units; it would only measure whether that has already happened under current enforcement. Comparator: the UPGo/McGill 2019 report's own housing-loss estimate, as the baseline a follow-up would be measured against. Confidence: medium for "better information is valuable"; not applicable for a quantified social-outcome range, since this action does not itself change housing outcomes.
Environmental ROI
Genuinely environmentally neutral — a research-commissioning action does not affect land use, construction, or consumption. Confidence: high for the neutrality claim.
Evidence
- Backgrounder §"The pre-bylaw academic baseline" · 2019 UPGo/McGill methodology and findings as the baseline for comparison
- Backgrounder §"Open questions / data gaps" · the specific, named gap this card addresses
Confidence & uncertainties
Medium-high confidence on feasibility (a research-commissioning action is administratively straightforward and has a direct precedent in the original UPGo study). This card does not claim any specific outcome from the study — including whether it would find the bylaw effective or ineffective — since that is exactly the unknown this card proposes to resolve.
Status
DRAFT — blocked on: identifying a specific research partner and funding envelope; no cost estimate exists in the evidence base beyond the general SSHRC-grant-scale comparator.

RC-str-02 — Publish a Post-Amendment Enforcement Follow-Up Scorecard
Card id: RC-str-02 · Issue: short-term-rental-regulation · Backgrounder: our research file for that page §"Toronto enforcement: the City's 2024 Auditor General audit and 2025–2026 program tightening" / §"Open questions / data gaps" · Trust: New load-bearing findings
Problem
The City's own June 2024 Auditor General audit quantified specific compliance gaps (at least 10% of transactions non-compliant or pirated and undetected by licensed companies; at least 250 potentially unregistered listings on secondary platforms; 1,438 operators potentially exceeding the 180-night rule; 545 potentially exceeding the 3-bedroom rule; 170 owners potentially holding more than one STR property) [backgrounder, source quote, "Toronto enforcement: the City's 2024 Auditor General audit and 2025–2026 program tightening"]. [Flagged 2026-07-19: the v2.0 backgrounder's own re-verified account of this audit (same section) confirms the 1,438/180-night, 170/multiple-property, and ~250/unregistered-listing figures directly, but no longer states a "545 potentially exceeding the 3-bedroom rule" figure anywhere in this document — a genuine drop/gap between v1.0 and v2.0's sourcing, not confirmed as either corrected-away or simply not yet re-mined. Needs a dedicated check against the audit's own primary text rather than being silently kept or silently dropped here.] City Council adopted bylaw amendments in April 2024 the audit itself describes as addressing "some of the enforcement challenges," and secondary reporting describes further 2025 measures (mandatory annual inspections, a platform-verification API) — but no source in this page’s evidence base confirms whether any of these measures actually closed the specific gaps the 2024 audit quantified.
Action
Council directs Municipal Licensing and Standards and the Auditor General's office to publish an annual follow-up scorecard, using the same specific metrics the 2024 audit already established (percentage of non-compliant/undetected transactions, count of unregistered listings on secondary platforms, count of operators exceeding the 180-night and 3-bedroom rules), so the same gaps can be tracked year-over-year against the 2024 baseline the City has already established.
Jurisdiction split
- City does: the entire action — this uses metrics the City's own Auditor General office already defined and measured once; formalizing it as an annual recurring report requires no new authority.
- City demands of Province: none.
- City demands of Feds: none.
Cost
Order of magnitude: low, non-capital — a recurring reporting obligation using data-analysis methods the Auditor General's office has already demonstrated it can perform (per the 2024 audit itself), comparable in scale to other City divisions' existing annual performance reporting.
Funding path
Existing Auditor General's office and Municipal Licensing and Standards operating budgets; no new funding mechanism required.
Who benefits, and how
Toronto residents and Council, via year-over-year visibility into whether enforcement is actually closing the specific gaps the City's own audit identified, rather than a one-time audit whose findings age without a documented follow-up.
Who bears the cost, and how
City taxpayers, via the marginal administrative cost of recurring data analysis and reporting — modest, since the underlying data-analysis method already exists per the 2024 audit's own demonstrated approach.
Financial ROI
Not separately quantified — this is a transparency/accountability action, not a direct fiscal one. Its indirect value is enabling better-targeted future enforcement resourcing decisions, which this card does not attempt to cost.
Economic ROI
Not yet estimable — a reporting action has no direct economic effect of its own. No comparator applicable. Confidence: low, largely inapplicable to this action type.
Social ROI
Directional only: sustained public visibility into a documented, quantified compliance gap (per the 2024 audit) supports continued public and Council pressure to close it, complementing RC-str-01's independent-study approach with an internally-generated, lower-cost recurring metric. Comparator: the 2024 AG audit's own quantified findings, as the baseline this scorecard would track against. Confidence: medium for "recurring visibility supports continued attention"; no quantified social-outcome range claimed.
Environmental ROI
Genuinely environmentally neutral — a reporting action does not itself affect housing stock or land use. Confidence: high for the neutrality claim.
Evidence
- Backgrounder §"Toronto enforcement: the City's 2024 Auditor General audit and 2025–2026 program tightening" · 2024 AG audit's specific quantified compliance findings
- Backgrounder §"Open questions / data gaps" · the named gap (no confirmed post-amendment follow-up) this card addresses
Confidence & uncertainties
Medium-high confidence on feasibility (uses an already-demonstrated methodology and existing City authority). This card is complementary to, not a substitute for, RC-str-01's independent academic study — the AG's own recurring scorecard would track the City's own enforcement-activity metrics, not provide the independent housing-loss/market-size estimate only an external study (RC-str-01) can provide, a distinction this card does not blur.
Status
DRAFT — blocked on: confirming this recurring report does not already exist in some form (this review did not locate a 2025 or 2026 AG follow-up on this specific program, but did not exhaustively search the Auditor General's full report archive either).
