GC terminates a sub without losing the schedule

Anonymised, illustrative composite. An Ontario general contractor terminated an underperforming electrical subcontractor 60% through rough-in on a 42-unit residential build, and had 48 hours to line up a legal replacement.

At a glance

  • • Ontario general contractor, 42-unit residential build, electrical sub terminated at 60% rough-in.
  • • Two replacement quotes: an unlicensed Master Electrician at $890/day, a Licensed Electrical Contractor at $1,050/day.
  • • Only the LEC was legally authorized to contract for the work.
  • • 24 remaining rough-in/trim days at the $160/day gap: $3,840 incremental cost, schedule held.

The situation

The termination itself was routine — missed milestones, rework the GC would no longer absorb. The harder problem was remobilizing fast enough that the schedule, and the liquidated-damages exposure sitting behind it, did not slip.

The problem

Two candidates surfaced within two days. One was a Master Electrician doing side work without his own contracting licence, quoting the lower day rate. Ontario’s Electrical Safety Authority is explicit that this option was never really available: “Licensed Electrical Contractors (LECs) are the only businesses in Ontario legally authorized to do electrical work”, and “qualified electricians and Master Electricians are not permitted to perform work for hire.” A Master Electrician’s licence lets them supervise work performed by a Licensed Electrical Contracting business; it does not let them contract directly, no matter how qualified the individual is.

The numbers

The unlicensed option quoted $890/day. The properly Licensed Electrical Contractor — carrying the 7-digit ECRA/ESA licence number the regulator requires — quoted $1,050/day, a $160/day gap. Over the estimated 24 remaining days of rough-in and trim, that gap totalled $3,840 more than the low bid.

That $3,840 was not really a choice against the low bid: because the low bidder could not lawfully contract for the work at any price, the LEC was the only lawful option, and $3,840 was small next to the liquidated-damages exposure the GC was trying to protect by remobilizing fast in the first place.

The rule that decided it

ESA’s licensing rule is binary, not a matter of degree: a Master Electrician without their own LEC licence is not permitted to perform electrical work for hire, full stop, regardless of skill or price. It also carries forward into inspection: ESA requires almost all electrical work to be reported by filing a notification of work, and an installation must be inspected before it’s concealed or buried — a chain that ties back to the contracting licence on file. Engaging the unlicensed option would have put every remaining notification and concealed-work inspection at risk, on top of the underlying illegality.

The outcome

The GC engaged the Licensed Electrical Contractor, the ESA notification transferred cleanly under the new licence number, inspections proceeded without disruption, and the 24-day schedule held at $3,840 more than the unusable low bid. See AI estimating for electrical contractors. A related dispute over undocumented verbal extras with a different electrical sub is in how an electrical sub priced eighty verbal extras, and a related loss of standing after a bad quarter is in how a contractor lost bonding after one bad quarter.

What it would have cost otherwise

Had the GC engaged the unlicensed Master Electrician on price alone, it would have contracted with someone the Electrical Safety Authority does not permit to perform electrical work for hire under any circumstance — putting every remaining notification of work and every concealed-work inspection on the project at risk, since ESA's inspection chain ties back to the licensed contractor of record. Unwinding that after the fact, mid-schedule, on a 42-unit build already behind on rough-in, would very likely have cost far more than the $3,840 gap the properly licensed option carried.

The tell

Verify licensing status before comparing day rates on any emergency trade replacement. A lower quote from an unlicensed party is not a cheaper option; it is not an option at all, and treating it as a price comparison rather than an eligibility filter is how a GC ends up choosing between two numbers when only one of them was ever real.

Why the licence, not the electrician, is what the law tracks

ESA's rule attaches the authorization to contract to the business licence, not to any individual's technical skill — a Master Electrician's own licence certifies competence to supervise and perform work, not to contract for it directly, which is why the unlicensed quote was never really a cheaper version of the same option. The 7-digit ECRA/ESA number the Licensed Electrical Contractor carried is also what ties every notification of work and every concealed-work inspection back to an accountable, authorized business — a chain the GC would have had to rebuild from scratch mid-job had it gone with the unlicensed option first and been forced to switch.

Takeaways

  • • Only a Licensed Electrical Contractor, carrying its own 7-digit ECRA/ESA licence, is legally authorized to contract for electrical work in Ontario — a Master Electrician’s licence does not substitute for it.
  • • Price is not the first filter when replacing a terminated electrical sub — legal authorization to contract is, and it removes options before cost comparison even starts.
  • • The licensing chain carries into notification and inspection, so an unlicensed replacement risks the whole remaining inspection sequence, not just the contract itself.
  • • $3,840 over 24 days was the real cost of the only lawful option — verify licensing before comparing quotes on any emergency replacement.
