RentLens
How our estimates work
Every valuation is grounded in real data — and shows you exactly what it's based on.
Verified RentLens properties
Real, verified rents from renters and owners — weighted by how trustworthy the evidence is.
CMHC market data
A market baseline calibrated to official CMHC figures, so you get a grounded estimate from day one.
Property characteristics
Beds, unit type, size, and features — a basement suite is priced against basements, not condos.
Explore rent prices across Ontario
See how average rents compare across Toronto and the GTA at a glance, so you know whether your area is a bargain or a stretch.

Frequently asked questions
Is RentLens free?
Yes. RentLens is free for renters in beta. The calculators work without an account; a free account lets you save properties, store rent history, and get a market valuation.
Which areas do you cover?
RentLens is launching for Ontario first, including the official provincial rent increase guideline and a rent map across Toronto and the GTA. More provinces will follow.
How is market value estimated?
We compare your unit against recent local rents for similar properties — factoring in unit type, size, and features — and return an estimate with a confidence range. Estimates get sharper as more verified renters contribute anonymous market data.
Is my data private?
Your properties and leases are tied to your account and visible only to you. Verified data may improve estimates for everyone in anonymized, aggregated form — and you can opt out anytime. You can export or delete your data whenever you like.
