What is the primary difference between CGL Form WA6000 and standard IBC 2100?

CGL Form WA6000 (Wawanesa) is a contractor-specific wording that requires explicit affirmative endorsements for Explosion, Collapse, and Underground (XCU) hazards and coordinates with Form WA6060 for 120-hour limited pollution. IBC 2100 is an occurrence-based standard commercial general liability form that contains standard underground and pollution exclusions unless modified by manuscript endorsements.

Why do vehicle-mounted booms and drills cause coverage disputes under Ontario standard CGL?

Section 239 of the Ontario Insurance Act dictates that automobile policies (OAP 1) respond to vehicular use, but standard auto policies exclude the operation of mounted machinery while stationary. Unless the CGL policy contains Form WA6000 or the auto policy attaches endorsement OPCF 30, damage caused by hydraulic booms, augers, or hydrovac nozzles falls into an uninsured coverage gap.

How does the 120-hour limited pollution liability rule (Form WA6060 / IBC 2313) operate in Ontario?

Under Form WA6060, environmental contamination (e.g., hydraulic oil spills, slurry runoff) is covered only if the spill is discovered within 120 hours (5 days) of the initial discharge, and formal written notification is submitted to the insurer within 120 hours of discovery.

How did the Ontario Court of Appeal rule on the faulty workmanship exclusion in Trillium v. Intact?

In Trillium Mutual Insurance Co. v. Intact Insurance Co. (2017 ONCA 389), the Court confirmed that the standard CGL "your work" exclusion only applies to the specific component being repaired or installed. Consequential physical damage to other property or building systems remains fully covered and triggers the insurer’s duty to defend.

The 4 Fatal Traps in Canadian Contractor Liability Wordings

Trap #1: Section 239 Auto Cross-Over

The Stationary Machinery Void (OPCF 30)

Standard commercial auto (OAP 1) covers vehicles while being operated on a highway. When a hydrovac boom, crane auger, or drill rig is stabilized on outriggers, auto insurers deny coverage under Section 239 of the Ontario Insurance Act. Without Form WA6000 or endorsement OPCF 30 bridging this into CGL, claims caused by mounted equipment are completely uninsured.

Trap #2: Form WA6060 Strict Timelines

The 120-Hour Pollution Discovery Trap

Limited pollution coverage does not cover ongoing or gradual contamination. If hydraulic fluid leaks into a municipal catch basin on Friday afternoon and is not formally reported in writing to the insurer by Wednesday morning (120 hours), the claim is barred under the policy warranty.

Trap #3: Bill 8 Underground Warranty

Expired Tickets Void Subsurface Defense

Insurers condition XCU coverage on strict adherence to Ontario One Call tickets. Under *Technicore v. Toronto (2012 ONCA 597)*, digging with a ticket that is 61 days old (1 day expired) voids the insurer's duty to indemnify, exposing the contractor to unlimited personal tort liability.

Trap #4: Faulty Workmanship Bounds

The Trillium v. Intact Consequential Rule

Carriers often attempt to deny entire claims by asserting the "your work" exclusion. Under *Trillium Mutual v. Intact (2017 ONCA 389)*, only the specific weld, valve, or pipe that failed is excluded; all resulting property destruction (flooded server rooms, collapsed roadways) triggers the mandatory duty to defend.
