The Direct Answer
When you convert your primary residence into a rental property, the Canada Revenue Agency (CRA) considers this a "deemed disposition." Effectively, you are treated as having sold the home at its current Fair Market Value (FMV) and immediately repurchased it as an investment. While the Principal Residence Exemption (PRE) typically shields your past gains, any future appreciation from the date of conversion becomes taxable as a capital gain upon the eventual sale.
The Deep Dive: Strategy Over Surprise
In a high-appreciation market like Oakville, failing to plan for this transition can lead to a significant tax bill down the road. The default rule triggers a "reset" of your property's cost base. For example, if you bought a detached home in Glen Abbey years ago for $900,000 and it is now worth $1.7 million at the time of conversion, that $800,000 gain is sheltered by your PRE. However, if the home grows to $2.1 million before you sell it, you will owe capital gains tax on that final $400,000.
Fortunately, savvy Halton investors often utilize a Section 45(2) Election. By filing this with your tax return, you can "elect" to defer the deemed disposition. This allows you to maintain the property's status as your principal residence for up to four additional years while renting it out, provided you do not designate another home as your primary residence during that time.
Local Nuance: 2026 Regulations in Oakville
As we move through 2026, Oakville homeowners must account for specific local shifts that impact rental profitability:
-
The 2026 Vacant Home Tax (VHT): Oakville is currently the only municipality in Halton requiring a Mandatory Annual Occupancy Declaration. Even if you are transitioning to a rental, you must submit this declaration by the April 30th deadline. If the property sits vacant for more than six months without a valid exemption, it may be subject to a 1% tax on the MPAC assessed value.
-
New Stormwater Fees: Starting this year, the Town has shifted infrastructure costs to a standalone fee. For a single-detached home in neighborhoods like Joshua Creek or Bronte, this adds approximately $137 per year (phased in at 50% for 2026). Ensure your lease agreements clarify if the landlord or tenant covers this utility-style charge.
-
CCA Warning: If you claim Capital Cost Allowance (CCA) depreciation to lower your rental income tax, you automatically void the Section 45(2) election, losing your ability to shield those years under the Principal Residence Exemption.
Essential Checklist for Oakville Landlords
-
Professional Appraisal: Obtain a certified FMV appraisal on the exact day of conversion to lock in your tax baseline.
-
Election Filing: Submit your Section 45(2) letter to the CRA with your 2026 tax return to avoid the "deemed sale."
-
Secondary Suite Compliance: If converting a basement in College Park or West Oak Trails, ensure it meets the latest Town of Oakville fire and building codes to remain a legal, insurable dwelling.
