Executive Summary

  • The 'Adventure in Trade' Risk. If you install services (water, sewer) or market the lot before selling, the CRA may classify the entire profit as **Business Income** (100% taxable) rather than a capital gain.
  • The 0.5 Hectare Boundary. Even if you don't subdivide, if your lot is larger than 1.24 acres, the CRA only considers the first half-hectare as part of your principal residence. The rest is a ticking tax time bomb.

A Note from Sean Omoh

"In 8 years of forensic real estate, I've learned that wealth transfer isn't about money. It's about family peace. When a plan is missing, families break. When a roadmap is clear, generational wealth flourishes. I don't sell you products; I build you the map so your family's biggest assets don't become their biggest fight."
