Short answer
Yes. Toronto says an undeclared property can be deemed vacant, the tax forms a lien on the property and a purchaser can become responsible. Buyers and sellers should address the declaration and tax status before closing.
The homeowner’s practical concern
A buyer focuses on the mortgage and title but does not request proof of the seller’s occupancy declaration or investigate a vacant-home-tax balance.
What the official rule says
Toronto requires annual occupancy declarations for applicable residential properties. From the 2024 taxation year, the VHT rate is 3% of Current Value Assessment; the City lists exemptions and supporting-document requirements.
What this does not guarantee
A sale, renovation, medical situation or principal residence may support an exemption only if the exact criteria and evidence are met. Power of sale is not itself an exemption.
A practical Ontario example
Illustration only: A property was not declared before sale. After closing, the City’s lien can affect the new owner even though the vacancy related to the former owner’s period.
What to check before changing the property or mortgage
Have the lawyer obtain the filed declaration, tax certificate, adjustment and appropriate seller protection. Keep the documents because the City may audit occupancy status later.
- How has the property actually been used each year?
- Was CCA claimed, and was any section 45 election filed?
- What was the property’s fair market value when its use changed?
- Where will refinance proceeds go, and can every transfer be traced?
- Which point needs written tax or legal advice before funds move?
Rajiv’s broker perspective
A mortgage approval answers whether a lender will finance the borrower and property under that lender’s policy. It does not confirm a tax deduction, principal-residence exemption, election or municipal-tax exemption. Before refinancing, changing occupancy or building a suite, I would separate the mortgage objective from the tax assumption, preserve the money trail and compare A-lender, alternative/B, MIC or private options only after the real use and exit plan are clear.
