Home Addition vs. Moving: The GTA Homeowner’s 2026 Financial Guide
With GTA home prices at record levels, the “add space or move” question has a new financial calculus. Here is a detailed breakdown to help you decide.
The True Cost of Moving in the GTA
| Transaction Cost | Amount |
|---|---|
| Ontario Land Transfer Tax (on $1.5M purchase) | ~$24,475 |
| Toronto LTT (City of Toronto only) | ~$24,475 additional |
| Real estate commission on sale (4-5%) | $48,000-60,000 |
| Legal fees (buy + sell) | $3,000-6,000 |
| Mortgage penalty (if breaking fixed) | $15,000-40,000 |
| Moving + overlapping costs | $10,000-30,000 |
| Total transaction cost | $100,000-160,000+ |
This is real equity that stays in your home if you renovate instead.
When Renovating Makes Sense
- You love your neighbourhood and school catchment
- Your home is in a sought-after area (additions recoup 60-90%)
- Your mortgage rate is well below current market rates
- The space you need is achievable within lot constraints
When Moving Makes More Sense
- Your lot cannot accommodate the needed addition
- You need a fundamentally different property type
- Renovation cost approaches 30%+ of current home value
- You’re on a high-rate variable mortgage and moving allows refinancing
