Professional Liability Insurance for Calgary Engineers
Calgary engineers face exposure to risk when designs or specifications are questioned. Professional liability (E&O) insurance helps manage claims tied to errors in technical planning or oversight.

Errors and omissions insurance for engineers in Calgary
As an engineer, failure to meet the terms of your contractual responsibilities can have serious consequences. Professional liability insurance in Calgary, otherwise known as errors and omissions (E&O) insurance, acts as a safeguard from the financial impacts of a lawsuit if a client brings a claim against you for professional negligence, errors or omissions in your services as an engineer. If you are sued as a result of damages that are covered under your insurance policy, E&O would cover the legal costs related to your defence.

What does professional liability insurance for Calgary engineers cover?

How much professional liability coverage does a Calgary engineer need?
Acera Insurance’s EasyCover program offers three limits of professional liability insurance for engineers in Calgary:
- $1 million
- $2 million
- $5 million
The policy limit is the maximum amount your insurer will pay if you have a covered claim. The amount of coverage that you need can really depend on your profession, company and the amount of people potentially impacted by a professional mistake.
While a $1 million limit can sound like a lot, that money can quickly be eaten up by legal costs, settlement and judgments as it moves through the court system. Research the average payout for a professional liability lawsuit in your engineering field and how common they are to help determine what your policy limit should be. In most cases, we advise carrying a minimum of $2 million in coverage.

Calgary engineering E&O claims examples
There are a variety of circumstances in which an errors and omissions could lead to a claim. They include:
Mechanical engineer: HVAC system design flaw
You made a miscalculation in the design of an HVAC system for a new hospital that results in inadequate air exchange rates. This causes delays in the building’s occupancy and added construction and remediation costs while the system is being fixed. Your client holds you financially responsible for the costs of corrective work.
Oil and gas engineer: Pressure conditions lead to unplanned shutdown
When designing a refinery upgrade for an oil and gas client, you fail to account for certain pressure conditions that lead to unplanned shutdowns. The operator claims lost revenue and additional engineering costs, and the client sues you to help negate some of the costs.
Electrical engineer: Misconfigured control system
When working on a project for a water treatment plant, a misconfigured control system leads to operational malfunctions, resulting in a lawsuit alleging negligence and demanding reimbursement of corrective costs by your clients.
It’s important to note that all EasyCover policies include retroactive coverage. As long as you have an active insurance policy with us, your policy would still respond even if a former client from a project completed years ago makes a claim against you.

Risk management strategies for Calgary contract engineers
Risk Assessments
Before starting a project, conduct a comprehensive risk assessment. Identify potential technical, financial, safety and scheduling risks. You can do this through brainstorming sessions, site reviews and stakeholder interviews.
Accurate Records
Keep detailed records of all contracts, agreements, timelines and deliverables. You should have terms that clarify your liabilities, change orders, payment schedules, dispute resolution and intellectual property rights.
Thorough Reviews
Implement robust design reviews to maintain regulatory and code compliance. Schedule peer reviews and third-party evaluations at key milestones of the project so you can identify and correct errors before they escalate.
Clear Communication
Adopt strong communication protocols for reporting issues, approving changes and updating your stakeholders. This helps to improve transparency and supports quick decision-making. Don’t forget to document and save all communications to help protect against disputes and claims.
Additional liability coverage options for Calgary engineers
EasyCover offers engineers in Calgary additional optional coverages to strengthen your protection. They include:
Commercial General Liability Insurance (CGL)
One of the most important types of business insurance, commercial general liability insurance helps protect you from claims of property damage or bodily injury arising from your operations and/or services.
Commercial general liability covers a wide range of incidents and will apply whether the incident happens at your office, at a client’s home or job site, or another location where you’re working. It’s important to note that this coverage doesn’t include your own tools, equipment or business property.
Coverage for EasyCover’s CGL policies start at $1 million but you can choose higher limits depending on your needs.
Directors and Officers (D&O) Liability Insurance
Directors and officers liability insurance provides protection if you face personal lawsuits alleging wrongdoing in your capacity as a director or officer of an organization – whether it’s your own business or another organization. Please note criminal acts or penalties are not insurable under law and therefore not covered under a D&O policy.
Cyber Liability Insurance
Digital threats that include cyberattacks, privacy breaches and data theft are an ongoing concern for engineering firms. Cyber liability insurance can offset the expenses from a security failure that might lead to ransom demands, operational downtime, legal expenses and reputational recovery. Cyber coverage terms can vary by policy so it’s important to examine your wording closely, with the help of your EasyCover broker, to know what is included.
