A standard commercial appraisal in Ontario typically takes 10 to 15 business days from signed engagement letter to delivered report, longer for complex assets, special-purpose properties, large portfolios, or files where the owner is slow to produce documents. Most Canadian appraisal firms do not publish turnaround times and there is no regulator-published benchmark; the most-cited Canadian figures come from one commercial mortgage broker and frame turnaround by report type rather than city or lender (LendCity, 2026).

Key takeaways

  • Standard frame: 10-15 business days from engagement letter to delivery for a typical short-narrative commercial report; longer for complex assets, special-purpose properties, or large portfolios.
  • One Canadian commercial mortgage broker reports report-type turnarounds of three to five weeks for full narrative, two to three weeks for limited-scope, three to seven days for desktop, and five to ten days for drive-by (LendCity, 2026) - treat as one broker's published observation, not an industry norm.
  • The single largest source of delay is incomplete documents at the engagement stage. The documents needed for a commercial appraisal list is the fastest schedule lever the borrower controls.
  • CUSPAP 2026 is the current standard, mandatory for AIC member assignments completed on or after April 1, 2026. The appraiser controls scope of work, authorized use, and authorized client - and those controls drive the timeline as much as they drive the fee.

Commercial appraisal timeline - the core questions

How long does a commercial appraisal take in Ontario?

For a standard assignment - small-bay industrial, suburban office, neighbourhood retail, low-rise multi-residential - delivery is typically 10 to 15 business days from the signed engagement letter, assuming documents and inspection access arrive in the first week. Complex assets (multi-tenant mixed-use, going-concern hotels, heritage masonry, environmental concerns) extend that window; large portfolios are scheduled in tranches. Report type segments it further: one Canadian commercial mortgage broker publishes typical turnarounds of three to five weeks for full narrative, two to three weeks for limited-scope, three to seven days for desktop, and five to ten days for drive-by assignments (LendCity, 2026). The 10-15 day frame reflects standard short-narrative practice; full-narrative work for institutional lenders or specialty assets sits above it.

What makes a commercial appraisal take longer?

Five factors push a standard engagement past the 15-business-day mark: document completeness (without leases, rent roll, operating statements, and capital-expenditure history in the first week, the income approach cannot start - a commercial appraisal preparation checklist closed before engagement signing routinely takes a week off delivery); inspection scope (full interior-and-exterior on a multi-tenant property requires tenant notice and coordinated access); comparable scarcity (heritage, special-purpose, and thin secondary-market assets require a wider search and a load-bearing cost approach); methodology load (going-concern allocation, DCF scenarios, ground-lease analyses); and review cycles (lender QC and internal sign-off by a second AACI on complex files).

Can I get a rush commercial appraisal?

Sometimes. A rush means the practitioner is reorganizing other deadlines to make room; that displacement carries a real cost, and a premium is the honest way to account for it. CUSPAP 2026 does not permit compressing turnaround by skipping required elements - a tighter timeline can only come from reordering work or narrowing scope (for example, accepting a drive-by inspection where the authorized use permits one). A rush quote that promises full-narrative depth in five business days without explaining how should be treated with caution.

What's the difference between turnaround and delivery date?

Turnaround is the appraiser's working window - engagement letter to draft sign-off. Delivery is when the report arrives in the authorized client's inbox. The two diverge in internal QC by a second AACI on complex files, in lender intake (where the appraiser-management workflow may hold a report 24-72 hours for its own review), and in client clarifications. A 15-business-day turnaround can still produce a 17-19-business-day delivery to a credit committee. Plan to the delivery date.

When should I commission the appraisal relative to my lender deadline?

Work backwards from the funding date and add buffer. For a federally-regulated bank refinance, engage at least four to six weeks before funding; one broker reports Big-Five commercial mortgage approval timelines of 45-90 days end-to-end (LendCity, 2026), inside which the appraisal sits alongside Phase I ESA, building condition report, and financial review. For an Ontario credit union, the same four-to-six-week buffer applies; FSRA's Commercial Lending Guidance (effective July 1, 2024) directs credit unions to use "a qualified entity, such as those with credentials issued by the Accredited Appraiser of the Canadian Institute" (FSRA, 2024). For CMHC MLI Select multi-residential, plan longer - as of November 15, 2024 an appraisal is required for every MLI submission regardless of unit count (RENX, 2024), and end-to-end CMHC-insured underwriting commonly runs 60-120 days. Private lender and MIC files are faster (5-15 days end-to-end per the same broker), with desktop or drive-by reports often the path. For litigation, Ontario Rule 53.03 requires expert reports served 90 days before trial and responding reports 60 days before trial; as of December 1, 2024, Form 53 also requires a signed certificate of authenticity (WEL Partners, 2024).

Do desktop and drive-by reports turn around faster?

Yes, with constraints. CUSPAP 2026 frames desktop, drive-by, exterior-only, and full interior-and-exterior as scope-of-inspection decisions, not separate report types - any inspection scope can sit inside a short narrative provided the scope is disclosed and appropriate for the authorized use. The broker-published turnarounds (three to seven days desktop, five to ten days drive-by) reflect the reduced inspection window, not a discount on the analytical work that follows. Federally-regulated commercial lenders rarely accept desktop-only for primary collateral underwriting; internal portfolio marks, certain insurance reinstatement estimates, and update reports off a recent prior assignment sometimes can. The appraiser, not the engaging party, decides whether the scope is defensible.

What happens if the appraiser misses the deadline?

The consequence depends on what the deadline anchors. A missed lender deadline can push funding, trigger a rate-hold expiry and re-quote, or leave the borrower bridging. A missed Rule 53.03 service window can result in the court refusing to admit the expert report, in costs sanctions, or in a leave application with no guarantee of success. A missed audit or IFRS quarter-close window can force the auditor to qualify the opinion or use an internal mark instead of the appraised value. The appraiser's professional obligation under CUSPAP 2026 is to produce a defensible report; the timeline is a contract obligation, not a CUSPAP rule. The cleanest mitigation is anticipation - engage earlier, lock the inspection slot fast, deliver documents in the first week, and treat the engagement letter's stated delivery date as the planning date, not the latest acceptable date.

When a missed deadline becomes a real problem

Three engagement contexts deserve flagging because the cost of a slip is structural. Refinance close: a commercial mortgage commitment letter carries a funding-by date inside which the rate hold, the appraisal validity period, and credit-committee approval all live; if the appraisal slips past the rate-hold expiry, the lender re-quotes at current market. The defensive move is engaging the appraiser the same week the term sheet arrives, not the week the conditions are due - see commercial appraisal for refinancing and the macro framing in our coverage of the Canadian CRE refinance cycle. Audit cycle: investment-property holders reporting under IFRS (IAS 40 fair-value model) need an effective-date valuation aligned to the quarter or year close; a late appraisal forces the auditor to fall back on a prior-period mark with a roll-forward justification, or to qualify the opinion. Litigation discovery and trial: Rule 53.03 deadlines are not negotiable in practice. A late expert report can be excluded; the four-part R v Mohan admissibility test (relevance, necessity, absence of any exclusionary rule, properly qualified expert) sits on top of the procedural service-date rule, and a late-served report invites a motion to strike before admissibility is even reached (R v Mohan, [1994] 2 SCR 9).

How to engage so the timeline is realistic

Three behaviours shorten almost every commercial appraisal engagement. Confirm the authorized use before signing - refinance, litigation, estate-and-tax, and insurance files each carry different scope-of-work implications, and telling the appraiser the authorized use up front prevents mid-engagement scope expansion (the most common source of last-week schedule slip); authorized use and authorized client are CUSPAP 2026's framing for who may rely on the report and for what purpose. Deliver documents the same week - an owner with leases, rent roll, operating statements, capital-expenditure history, surveys, environmental history, and zoning correspondence in a single folder at engagement signing routinely shaves a week off delivery. Lock the inspection slot first - for multi-tenant properties, tenant notice and access coordination is the first long-pole item.
