The projects were chosen for what they can teach. Their results do not represent all Canadian megaprojects. A recorded issue does not establish a single cause or assign responsibility.

Fourteen issue types

Evidence and remaining gaps

Only documented problems count toward the project total. Constructive partnerships are recorded separately. Unresolved evidence and blank cells do not prove that a problem never occurred.

01

Optimistic baseline

Unresolved evidence

A source documents that the cost or schedule approved at sanction understated what similar work required, omitted known risks, or rested on assumptions later found untested.

02

Contractor productivity and unreliable commitments

No qualifying evidence established, not proof of absence

A source documents contractor productivity well below the tender or plan, or commitments on dates and sequences that proved unachievable.

03

Ground conditions

No qualifying evidence established, not proof of absence

A source documents foundation, soil or buried-infrastructure conditions that differed from the baseline assumptions and affected cost, schedule or design.

04

Quality defects and rework

No qualifying evidence established, not proof of absence

A source documents rework, defects or failed inspections on structures, track, vehicles or systems.

05

Pandemic

Documented problem

A source attributes additional cost, productivity loss, supply-chain disruption or schedule loss to COVID-19.

06

Indigenous rights and consultation

Documented problem

A source documents consultation, accommodation, litigation or partnership with Indigenous nations shaped the project’s scope, schedule, approval or structure. Constructive partnerships are recorded separately and excluded from problem totals.

07

Political pressure and weak governance

Documented problem

An inquiry, audit, review or peer-reviewed study documents political pressure on decisions or weak, divided or uninformed oversight, with a documented effect on the project.

08

Owner-contractor disputes

No qualifying evidence established, not proof of absence

A source documents a major claim, settlement, arbitration or lawsuit between owner and contractor during delivery.

09

Labour shortages and strikes

No qualifying evidence established, not proof of absence

A source documents a skilled-labour shortage or industrial action that delayed work.

10

Weather and natural hazards

No qualifying evidence established, not proof of absence

A source documents floods, wildfires, drought, storms or extreme winter weather that disrupted construction or commissioning; ordinary seasonal conditions or future risks alone do not qualify.

11

Systems integration and commissioning

Outside the project or issue boundary

A source documents signalling, control, software or integration defects that delayed commissioning or caused outages.

12

Supply-chain delays

No qualifying evidence established, not proof of absence

A source documents late delivery of materials, vehicles, cables or specialized equipment.

13

Regulatory and permitting

Documented problem

A source documents environmental, regulatory or permit delay, non-compliance, reversal or refusal.

14

Late scope and design change

No qualifying evidence established, not proof of absence

A source documents owner-, regulator- or site-driven changes to scope or design after contract award.
