How to Write a Construction Feasibility Study in Canada: A CPA's Framework
A practical, numbers-first framework for testing whether a construction project should be built, financed and insured, covering market, site, cost, tax, funding, sensitivity testing and risk management.
1. Why a Feasibility Study Comes First
Construction projects fail on paper long before they fail on site. A building that looked profitable on a napkin can lose money once land costs, servicing, financing charges, holdbacks, contingency and sales tax are counted properly. A feasibility study is the low-cost way to find that out, because changing a spreadsheet is cheap and changing a half-built foundation is not.
A good study also does more than say yes or no. It tells you what must be true for the project to work: what the building must sell or rent for, how much it can cost, how long it can take and how much equity you need. Those thresholds become the guardrails you manage against once the project is approved.
This is a framework, not a template to fill in blindly. Every project differs, but the logic is consistent. Our CFO advisory services and business planning and financial modeling work follow the same approach: test the assumptions, price the risk and make the numbers traceable.

2. The Ten-Part CPA Framework
| # | Section | Question it answers | Key output |
|---|---|---|---|
| 1 | Project concept | What are we building, for whom? | Scope, unit mix, size |
| 2 | Market and demand | Will it sell or lease, at what price and pace? | Pricing, absorption, comparables |
| 3 | Site and approvals | Can it be built here, and what will approvals take? | Zoning, servicing, timeline |
| 4 | Cost budget | What will it cost, including contingency? | Line-item budget |
| 5 | Schedule | How long will each phase take? | Milestones, cash-flow timing |
| 6 | Financing | How much debt and equity, and on what terms? | Sources and uses |
| 7 | Tax | What do income tax and GST/HST do to cash and profit? | Tax cash-flow adjustments |
| 8 | Pro forma | Does it make an acceptable return? | Profit, margin, return metrics |
| 9 | Risk and sensitivity | What breaks the project? | Scenario table, mitigations |
| 10 | Recommendation | Go, no-go or revise? | Decision and conditions |
3. Market and Demand Analysis
Start with demand, because every revenue line depends on it. Define the end user, review comparable projects and pricing, and estimate how fast units will sell or lease, known as absorption. For commercial space, firm leases or letters of intent carry far more weight than general interest.
- Demographics and demand drivers: population growth, employment, incomes and household formation in the catchment area.
- Comparable projects: prices, rents, unit sizes, incentives and days on market for recent and competing projects.
- Supply pipeline: what else is under construction or approved nearby and when it delivers.
- Absorption: units sold or leased per month, tested against your selling or lease-up period.
Use current local data. For example, CMHC's 2026 outlook projects Saskatoon housing starts of about 3,550 and Regina starts of about 1,500 in 2026, down from 2025, while the Prairies are expected to keep sales strong and lead price growth. Figures like these frame demand, but your study should rely on your own site-level comparables.

4. Site, Zoning and Technical Review
Confirm that the project can legally and physically be built, and how long approvals will take. Time spent in approvals carries interest, taxes and opportunity cost, so approval risk belongs in the model, not just in the planning file.
| Item | Why it matters to feasibility |
|---|---|
| Zoning, density, setbacks, parking | Determines what you can build and therefore revenue |
| Servicing capacity | Water, sewer and power upgrades can be large unplanned costs |
| Geotechnical report | Soil conditions drive foundation design and cost |
| Environmental site assessment | Contamination creates remediation cost and lender hesitation |
| Permit and approval status | Sets the earliest start and the carrying period |
| Appraisal | Supports land value and projected as-complete value for lenders |
5. Building the Cost Budget
A budget lenders trust is built line by line and separates three layers: land and acquisition costs, hard costs (construction) and soft costs (design, permits, legal, financing, marketing and project management). Add contingency and an allowance for escalation over the construction period.
Escalation varies by province, project size and procurement route. Turner & Townsend notes that fluctuating tariffs add a premium to risk allowances, that labour constraints are likely to worsen in 2027 and that geopolitical instability is an upside risk to material costs. Treat those as inputs to your contingency, not a substitute for supplier quotes.
- Obtain firm or indicative quotes from the general contractor and key trades where possible.
- Model holdbacks (commonly 10% of each trade payment in lender guidance) as a cash-flow timing item.
- Include an interest reserve so construction-period interest is funded, not forgotten.
- Separate owner-supplied costs, such as your own labour or equipment, from third-party costs.
6. Financing and Lender Expectations
Feasibility must include a financing plan, because debt terms and equity requirements shape both return and risk. Published lender guidance gives typical ranges, which vary by lender, project type and borrower strength.
| Item | Commonly cited range | Note |
|---|---|---|
| Loan-to-cost | About 60% to 80% of total project cost | Depends on lender, risk and project type |
| Equity | Often 20% to 40% | Owned land can count toward equity |
| Condo pre-sales | Often 50% to 70% of units | Firm agreements with deposits |
| Underwriting time | Roughly 4 to 12 weeks | Institutional lenders |
| Draw schedule | Milestone-based | Foundation, framing, lock-up, finishing and so on |
| Cost-to-complete test | At each draw | Overruns may require extra equity |
Lenders also review the borrower: completed-project history, two to three years of financial statements and personal and corporate returns. If you need compiled statements for this purpose, see our guide to preparing for a compilation engagement and what Canadian business owners need to know about compilations. If you are raising equity from outside investors, our post on how an entrepreneur secures investment with a business plan covers what investors expect to see.
7. Tax and GST/HST Considerations
Tax changes both cash flow and profit, so it belongs in the study from the start. The points below are general; the right treatment depends on the structure and the facts, so confirm with a qualified tax professional.
- Builder input tax credits: a GST/HST-registered builder in commercial activity can generally recover GST/HST paid on construction costs as input tax credits, which helps construction-phase cash flow.
- Deemed self-supply on rentals: when a residential rental unit is first occupied, the builder can be treated as having sold and repurchased the building, with GST/HST calculated on fair market value rather than cost. That can be a large cash event at completion, so model it.
- Purpose-built rental rebate: a federal rebate of the GST component, introduced in late 2023, may apply to qualifying new purpose-built rental projects, with provincial treatment varying. Eligibility rules are detailed; do not assume the rebate without checking the current conditions.
- Income tax: consider whether the project is held as inventory for sale or capital property for rent, the timing of income and the use of capital cost allowance where applicable.
- Land and holding costs: property taxes and interest during construction may be capitalized or deducted depending on the circumstances.
8. Pro Forma and Sensitivity Testing
The pro forma pulls everything together: total development cost, revenue, financing costs, tax and profit. The key discipline is testing. Lender guidance suggests stress-testing cost increases of around 10% to 15% and revenue shortfalls, because a project that only works at best-case numbers is not feasible.
| Scenario (illustration only) | Cost change | Revenue change | Delay | Result to check |
|---|---|---|---|---|
| Base case | 0% | 0% | None | Target margin met? |
| Cost overrun | +10% | 0% | None | Margin and equity need |
| Severe overrun | +15% | 0% | None | Does it still clear lender tests? |
| Soft market | 0% | −10% | Slower sales | Debt service and carrying costs |
| Combined stress | +10% | −10% | +6 months | Break-even and breach points |

Bar lengths are illustrative, not calculated from a real project. They show why margins can shrink faster than the individual shocks suggest. Build the real numbers in your own model.
9. Risk Management: Financial Risk and Business Risk
Risk management is the heart of a feasibility study. Separate financial risk, which hits the numbers directly, from business risk, which threatens your ability to execute, and assign each a control.
| Risk | Type | Mitigation |
|---|---|---|
| Cost overruns and material inflation | Financial risk | Contingency, fixed-price contracts where possible, escalation clauses |
| Interest rate and refinancing risk | Financial risk | Rate caps or fixed terms, interest reserve, conservative leverage |
| Revenue shortfall or slow sales | Financial risk | Pre-sales or pre-leases, price sensitivity, phased release |
| GST/HST and cash timing surprises | Financial risk | Model self-supply and ITC timing; tax advice early |
| Approval delays and regulatory change | Business risk | Pre-application meetings, schedule buffer, staged commitments |
| Labour shortages and trade availability | Business risk | Early trade commitments, relationships, realistic schedule |
| Contractor or partner failure | Business risk | Due diligence, bonding or security, clear contracts |
| Weak records and reporting | Business risk | Project-level books, monthly reporting, cost-to-complete tracking |

10. Structure, Books and Reporting
Many builders and developers hold each project in its own company, which separates liability and simplifies lender security. The cost is more entities to keep clean, so plan the accounting before the first dollar moves. Our post on managing bookkeeping for multiple companies covers intercompany balances, shared costs and consolidation.
- Project-level books: track budget versus actual by cost code so cost-to-complete is always current.
- Draw support: keep invoices, progress certificates and lien-period records ready for each lender draw.
- Review readiness: organized records help with lenders, partners and the CRA; see preparing books for accountant or CRA review.
- Specialized needs: complex structures, partnerships or cross-border funding may call for our specialized services, while ongoing bookkeeping and tax filings fall under our core accounting and tax services.
If newcomer entrepreneurs or foreign partners are involved, a documented plan matters beyond lenders; see can a business plan help with immigration for how plans are used in program applications.
11. The Go, No-Go or Revise Decision
End the study with a clear recommendation and the conditions attached to it. Decision rules set in advance prevent optimism from taking over later.
- Go: numbers pass under base and stress cases, and conditions are met.
- Revise: the idea is sound but scope, price, structure or financing needs to change.
- No-go: it fails under reasonable stress and cannot be fixed without unrealistic assumptions.

13. Frequently Asked Questions
What is included in a construction feasibility study?
It usually covers the project concept, market and demand analysis, site and zoning review, a cost estimate with contingency, a schedule, a financing plan, a pro forma with revenue and profit, tax considerations, a risk assessment, sensitivity tests and a clear go, no-go or revise recommendation.
How much does a feasibility study cost in Canada?
Costs vary widely with project size, complexity and how much third-party work is needed, such as appraisals, geotechnical and environmental reports and quantity surveyor input. A simple desktop study costs far less than a full lender-grade study. Ask for a scoped quote and confirm what is included.
How long does a construction feasibility study take?
Most take several weeks, depending on how quickly site, market and cost data can be gathered. Third-party reports such as environmental and geotechnical assessments often set the pace, and municipal zoning questions can add time.
What contingency should a construction budget include?
Published lender guidance commonly cites at least 5% to 10% of hard construction costs, with more for complex sites or early-stage designs. The right figure depends on design completeness, site risk, procurement method and market conditions, so confirm it with your cost consultant and lender.
Do I need a CPA to write a feasibility study?
It is not a legal requirement, but a CPA helps with the financial model, financing structure, GST/HST and income tax treatment, cash flow and sensitivity testing. Lenders and investors also tend to trust figures built on sound accounting and tied to supporting documents.
14. Final Thoughts
A feasibility study is the cheapest insurance a construction project will ever buy. It forces honest answers about demand, cost, tax and funding while changes are still easy, and it turns risk management into numbers: how much financial risk the project can absorb, and which business risk could stop it. Write it with current data, test it under stress and let the result, not enthusiasm, decide whether to build.
