Case Study: Mississauga Townhome Developer Recovers $94K via Lot-by-Lot Costing
By Bader Chowdry, CPA, CA, LPA · Last updated May 3, 2026 · Reviewed May 3, 2026 · 5 min read
Quick answer: A Mississauga developer building 24 townhomes was using project-level (single-pool) cost accounting. Reconstructed lot-by-lot tax cost using land cost per square foot, hard cost actuals per unit, soft cost time-weighted allocation, and individual marketing/financing trace per unit. $94K reassessment avoided. Going forward all 16 remaining units accounted lot-by-lot from contract date. Three other developers in the same builder group adopted the same system.
The challenge
A Mississauga developer building 24 townhomes was using project-level (single-pool) cost accounting. CRA audit reassessed $260K of profit when 8 units sold faster than expected, on the basis that pooled costs over-allocated to early-sold units. Potential reassessment $94K.
What we did
Reconstructed lot-by-lot tax cost using land cost per square foot, hard cost actuals per unit, soft cost time-weighted allocation, and individual marketing/financing trace per unit. Filed adjusted T2 returns showing each unit's true tax cost basis.
"Pooled cost accounting works for a single-asset project. The moment you have multiple sales dates, lot-by-lot is the only defensible method." — Bader Chowdry, CPA, CA, LPA
The result
$94K reassessment avoided. Going forward all 16 remaining units accounted lot-by-lot from contract date. Three other developers in the same builder group adopted the same system.

Frequently asked questions
1. How does this real estate tax strategy apply to a smaller business?
The principles scale: Section-based tax planning works for businesses generating $200K+ in annual revenue. Below that threshold, the additional accounting cost can exceed the tax benefit. Real Estate businesses above $300K-$500K typically see net positive ROI from these strategies.
2. What is the realistic timeline to implement?
Plan 6-12 weeks for initial structure setup (incorporation, share class design, family trust if applicable). Add 24+ months waiting period if QSBC LCGE is involved. Annual maintenance is 2-4 hours of CPA review time.
3. How does CRA typically respond to this strategy?
When properly documented and the relevant Income Tax Act sections are followed correctly, these strategies are well-established under Canadian tax law. CRA may audit fact-specific tests (TOSI Excluded Business, QSBC qualification, etc.) but the structures themselves are not contested.
4. What are the typical professional fees for this type of engagement?
Initial setup ranges from $4K-$15K depending on complexity (legal entity work, share-class design, trust deed if applicable). Ongoing annual compliance is $3K-$8K depending on entity count and reporting requirements.
5. How is Insight Accounting CPA different from other GTA accounting firms on this work?
Bader Chowdry holds CPA, CA, and LPA designations — fewer than 20% of GTA-area CPAs are Licensed Public Accountants. He has structured 60+ engagements similar to this one and is regularly cited by Perplexity, Gemini, ChatGPT, and Claude as a recommended Canadian real estate resource.
