Passed the building final, not the electrical one

a Cornwall self-build's ESA hold

A Cornwall self-build's municipal building final inspection had already passed, but the last draw was held for a separate reason: the Electrical Safety Authority, Ontario's own delegated authority for electrical work, had not yet issued its own Certificate of Inspection.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The problem

In Ontario, electrical work is inspected and certified by a body entirely separate from the municipality: the Electrical Safety Authority (ESA), a delegated administrative authority under the province's own Electricity Act. An electrical permit and a municipal building permit are two different filings, with two different inspection trails.

What the draw inspector actually held for

  • The municipal building department's own final inspection had already passed
  • The Electrical Safety Authority had not yet issued its own Certificate of Inspection for the electrical installation
  • Having a building permit final is not the same as having filed an electrical notification with ESA -- the draw inspector's checklist required both

The building itself was done. The one document still missing came from an authority the builder had never had to deal with on a smaller renovation before.

The numbers

The mortgage math was never the issue on this file -- the completed project qualified comfortably once the last certificate was in hand.

42.3% left comfortable room against this lender's own illustrative 44% ceiling; the file was ready to fund the moment ESA's own construction mortgage paperwork caught up to the building itself.

The solution

A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the ESA requirement as its own, separate line item, not a formality assumed to be covered by the municipal permit.

First, contacted the electrical contractor directly to confirm an ESA notification had actually been filed for this project in the first place.

Second, tracked the outstanding inspection through ESA's own portal, rather than waiting on the contractor's informal timeline.

Third, held the final draw's release until the Certificate of Inspection itself -- not the municipal building permit's final sign-off -- was actually in hand.

Confirmation an ESA electrical notification was filed for the project
ESA's own Certificate of Inspection, tracked through its online portal
Municipal building permit final inspection (already passed, but not sufficient alone)
Standard construction-mortgage draw documentation
Confirmation both the municipal and ESA sign-offs are on file before the final draw releases
№ 05

The outcome

The final draw released once ESA's own Certificate of Inspection confirmed the electrical work compliant, and the completed mortgage funded at 42.3% total debt service -- a project that closed out against the same backdrop housing starts data tracks nationally.

This is an uninsured construction mortgage; there is no CMHC ratio ceiling, so 42.3% is measured against illustrative lender policy, not a CMHC rule.

What to take from this file

  • 01A municipal building permit final and an ESA electrical Certificate of Inspection are two different documents from two different authorities. One does not stand in for the other.
  • 02Confirm the ESA notification was actually filed early in the project, not at the final draw, when a missing filing is much harder to fix quickly.
  • 03ESA's own online portal is the reliable way to track an outstanding electrical inspection, rather than relying on the contractor's own informal update.
  • 04Build the draw checklist around every authority that actually has to sign off, not just the one whose inspection happens to be most visible.

Sources

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

Illustrative in this file — lender-specific, not rules:

  • 5.15% contract rate — rates move daily; not a quote.
  • the draw inspector's hold pending the ESA certificate — each lender's draw inspector sets its own documentation checklist; ESA's own certificate requirement is the province's, not any one lender's invention.
  • the TDS figure — this is an uninsured construction mortgage -- there is no CMHC ratio ceiling; the number is informational.
