Renting out a unit in St. Catharines
St. Catharines is the largest city in Niagara Region, on Lake Ontario at the north end of the Welland Canal, and home to Brock University. Its rentals range from apartment buildings downtown and along the main corridors to houses, townhouses and condominium units, with demand from Brock students and from people who work across Niagara.
We take on individually owned condominium units, apartments and townhomes in St. Catharines, including units in buildings that SIREG managed. Send the building address and unit number and we confirm coverage before anything else happens.
For SIREG and Simple Investor owners
Tenant.ca works under a management agreement: you remain the landlord and the lease stays between you and your tenant. We do not lease your unit from you, and this is management, not a guaranteed-rent program: rent is collected from your tenant and shown in your owner portal, payment by payment.

Source: CMHC Rental Market Survey, October 2025, data tables for the St. Catharines-Niagara CMA, published December 2025. Averages cover occupied and vacant units in purpose-built rental buildings, so they usually sit below what a vacant unit is advertised for, and they do not describe any one unit.

Common questions
Management is $98 per month plus HST for each condo or apartment unit; houses start at $148 per month plus HST. Tenant placement, at one month's rent plus HST, applies only when a vacant unit needs a new tenant.
