Modern log cottage on a granite Ontario lakeshore at golden hour

Built for Ontario cottage-country hosts

You bought a cottage.
Now you owe the township.

Cottage-country bylaws change every season and renewal dates are buried in fine print. WelcomeMAT does three things, properly: reminds you 60 days before every licence renewal, generates the pre-filled MAT form your township actually accepts, and tells you the day your municipality changes a rule.

Three jobs. Done properly.

What WelcomeMAT does

We don't do everything. We do the three things that cost you money.

Licence-renewal reminders, 60 days out

Forgetting to renew your municipal STR licence is the #1 reason cottage hosts get fined. We track every renewal — licence, insurance, fire inspection, septic pump — and warn you 60 days before, then 30, then 7. A phone calendar can't do that across three properties.

Pre-filled MAT remittance forms

We don't just calculate the number. We generate the actual quarterly remittance form your township accepts — pre-filled with nights, gross revenue, MAT collected, and payment instructions. Sign, send, done. Knowing the number is easy. Filing the form is the part that ruins a Sunday.

Bylaw-change alerts

When your municipality changes the MAT rate, tightens the licence cap, or adds a new requirement, you hear it from us — not from the bylaw officer. Every verified municipality is monitored against its source bylaw page.

Also included ↓

Year-end tax package your accountant can hand straight to CRA
Booking sync via iCal or Google Calendar
Expense tracking against CRA categories
Document vault for insurance, permits, inspections
AI-drafted guest message templates

Who this is for

Cottage-country hosts with 1–3 properties.

If you bought a cottage in the last few years, inherited one, or you're juggling renewals across a couple of townships, WelcomeMAT is built for you. If you're a Toronto Airbnb pro with a downtown condo — Airbnb already remits your MAT and your rules don't change. You don't need us.

New cottage owner

Just bought, just inherited, or about to close. Get a 90-day compliance checklist for your exact township.

Multi-property owner

Two or three cottages across different municipalities. Side-by-side requirements, one renewal calendar.

Accidental host

Started renting the family place and now there's real income, real MAT, and a real CRA filing to think about.

Verified municipalities

Verified bylaw guides for 68 Ontario municipalities.

We only publish a guide once we've confirmed the licence, insurance, fire, septic and MAT rate against the current source bylaw — not scraped, not generated.
