Most Ontario zoning by-laws never mention short term rentals, which quietly makes them prohibited. Thorold did the opposite: Comprehensive Zoning By-law 60-2019 defines the use by name and permits it in every residential zone. That makes Thorold one of the few Ontario municipalities where the zoning question, the one that sinks hosts in Whitby, Barrie and Halton Hills, is answered in your favour before you start.
Everything below is cited to the by-law text itself, downloaded from the City of Thorold's zoning page, with the licensing picture from the City's Residential Rental Licensing program and council's public record. One layer is still moving in 2026, and we flag exactly what to confirm before you list.
Quick Summary
What the By-law Actually Defines
Thorold's zoning does something most Ontario municipalities have not done: it names the use. From the definitions part of Comprehensive Zoning By-law 60-2019:
"Short Term Accommodation Rental: means a short-term rental for all or part of a dwelling unit used to provide sleeping accommodations for any rental period that is less than twenty-eight (28) consecutive days to a renter in exchange for payment. This excludes bed and breakfasts, hotels/motels, and accommodations where there is no payment." City of Thorold Comprehensive Zoning By-law 60-2019, Part 2 Definitions
Three practical consequences. First, both whole home rentals and single room rentals are captured, "all or part of a dwelling unit." Second, the 28 day line is the boundary: a stay of 28 days or longer is simply not a short term rental under this by-law. Third, a bed and breakfast is a different use with its own rules, covered below.
Permitted in Every Residential Zone
Table 6.2 of the by-law lists the permitted uses for Thorold's residential zones. "Short term accommodation rental" appears with a permission dot in all four zone families: R1, R2, R3 and R4, alongside accessory uses like home occupations and second dwelling units. Contrast that with the cities where we spend most of our compliance time: Whitby's zoning never mentions the use (not permitted anywhere), Halton Hills the same, and East Gwillimbury confines it to Mixed Use zones. Thorold's welcome mat is genuinely unusual.
The permission was added by amending By-law 31-2021, which listed short term accommodation rental as a specified accessory use in the residential zones, subject to regulations.
The Conditions You Must Confirm
Here is the honest catch. The Table 6.2 permission carries a footnote: "This use is subject to regulations outlined in Part 3, Generals." But the Part 3 document posted on the City's website does not contain a short term rental section, its numbering skips from home occupations to lot frontage. The operating conditions, things like owner occupancy, parking or room limits, live in amending By-law 31-2021 and are not visible in the posted consolidation.
Licensing: What Applies Today and What Is Coming
Thorold has licensed long term rentals for years through its Residential Rental Licensing (RRL) program, born from the Brock University student rental market. Licences run for two years, and the program exempts larger apartment buildings, owner occupied homes renting up to two bedrooms, and hotels and B&Bs.
The short stay layer is in motion, and it pays to know the direction. In October 2024, council directed staff to prepare amendments to the RRL by-law that would, as proposed:
- Add provisions specific to short term rental and bed and breakfast establishments
- Create a demerit point system for residential rental licences
- Prohibit advertising a rental unit without a valid licence
A statutory public meeting followed in March 2025, and the City's review of the RRL by-law remained open into 2026. To be precise about status: these were directed and consulted on, and we could not confirm final adoption from the City's public documents as of September 2026. That is exactly why the first phone call before listing goes to the licensing division, ask what a short stay operator needs today, and whether the new provisions are in force.
Bed and Breakfasts Are a Separate Use
The short term rental definition explicitly excludes bed and breakfasts, and the zoning treats them differently:
"Bed and breakfasts are only permitted in single detached dwellings, semi-detached dwellings, and street townhouses." City of Thorold Comprehensive Zoning By-law 60-2019, Table 6.2, Footnote 2
B&B regulations sit in Part 3, Section 3.2 of the by-law, and the RRL program exempts B&Bs from rental licensing. If you live in your home and want to host a few rooms in the traditional style, that is the lane; the short term rental rules above are the lane for Airbnb style stays.
Why Thorold Is Worth a Look
Thorold sits in the geographic middle of Niagara: Brock University borders it, downtown St. Catharines is minutes north, the Welland Canal locks draw ship watchers all season, and Niagara Falls is roughly a 15 minute drive. Entry prices run far below Toronto, and the neighbouring markets are tightening, St. Catharines requires the STR to be your primary residence, and Niagara Falls confines vacation rentals to commercial zones. A municipality that says yes in residential zones, next door to two that mostly say no, is a real positioning advantage while it lasts.
The 28 Day Alternative
If the conditions turn out not to fit your situation, particularly for investors who would not live on site, the by-law's own definition provides the fallback: stays of 28 days or longer are not short term rentals at all. Furnished mid term rentals operate as ordinary tenancies, and Thorold's demand base is strong for exactly that: Brock students and visiting faculty, healthcare placements, and trades working Niagara's construction pipeline.
Frequently Asked Questions
Can I legally run an Airbnb in Thorold?
Thorold is one of the few Ontario municipalities whose zoning by-law expressly permits short term rentals in residential zones. Comprehensive Zoning By-law 60-2019 defines a Short Term Accommodation Rental and Table 6.2 lists it as a permitted use in the R1, R2, R3 and R4 zones. The use is listed among accessory uses and is subject to regulations added by amending By-law 31-2021, so confirm the conditions for your specific property with the City's planning division before listing.
What counts as a short term rental in Thorold?
The zoning by-law defines a Short Term Accommodation Rental as a rental of all or part of a dwelling unit providing sleeping accommodations for any period less than twenty eight consecutive days in exchange for payment. Bed and breakfasts, hotels and motels, and stays with no payment are excluded. Rentals of 28 days or longer fall outside the definition entirely.
Do I need a licence to run a short term rental in Thorold?
Thorold has run a Residential Rental Licensing program for years, with licences valid for two years. In October 2024 council directed staff to add provisions specific to short term rentals and bed and breakfasts, a demerit point system, and a prohibition on advertising unlicensed units. The City's review of the by-law was still underway as of 2026, so ask the licensing division (RRL@thorold.ca, 905 227 6613) what applies to short stays today before you list.
Does Thorold require the operator to live in the property?
The zoning by-law's permitted use table does not state an owner occupancy rule, but two signals point that way: the use is listed as an accessory use, and the City's 2025 public meeting notice on licensing changes described owner occupied short term rental units in residential areas. Get the City's written answer for your situation, especially for a property you would not live in.
Can I run an Airbnb in an investment property in Thorold?
This is the exact question to put to the City in writing. Zoning permits the use in all residential zones, but the accessory use listing and the owner occupied language in the licensing review may limit non resident operators. If whole home short stays turn out to be restricted, rentals of 28 days or longer are ordinary tenancies and remain fully available for investors.
What about bed and breakfasts in Thorold?
A bed and breakfast is a separate use from a short term rental in Thorold's zoning, and it is expressly excluded from the Short Term Accommodation Rental definition. Table 6.2 permits bed and breakfasts only in single detached dwellings, semi detached dwellings and street townhouses, with regulations in Part 3, Section 3.2 of the zoning by-law.
Is there a night cap or a municipal accommodation tax in Thorold?
The zoning by-law defines the use by stay length (under 28 consecutive days), not by nights per year, so there is no zoning night cap. We found no municipal accommodation tax program for Thorold as of September 2026, unlike Niagara Falls. Confirm with the City before budgeting, since Niagara municipalities have been adding MAT programs.
Why is Thorold attractive for short term rentals?
Location and price point. Thorold sits in the middle of Niagara: Brock University is on its doorstep, downtown St. Catharines is minutes away, and Niagara Falls is roughly a 15 minute drive. Property prices run well below Toronto, and the zoning welcome mat is something most Ontario cities cannot offer.
Could Thorold's rules get stricter?
The licensing side is actively evolving. Council's 2024 direction included a demerit point system for rental licences and a ban on advertising a rental without a valid licence, and the licensing by-law review was still open in 2026. Operators should expect a licensing framework specific to short stays and keep documentation ready. The zoning permission itself would take a separate amendment to change.
What are my options if short stays do not fit my situation?
Rentals of 28 days or longer sit outside the short term rental definition and operate as standard tenancies. Thorold has steady mid term demand from Brock students, visiting faculty, healthcare workers and trades on Niagara projects. Nurture manages both short term and mid term rentals across the region.
Thinking about hosting in Thorold?
We can confirm the current rules with the City for your specific property, then handle listing, pricing, guests and cleaning. Short term or mid term, whichever the rules and the numbers favour.
