The Practice

My strength is finding the shortest path to the best possible outcome for my clients. Jim Davidson, Partner and Head of the Insurance Group

Insurers do not retain outside counsel for routine files. They retain counsel when a matter carries real exposure: a serious bodily-injury claim, a multi-party construction or fire loss, a coverage question that decides whether the policy responds at all, or a class proceeding that puts an entire line of business in issue. Those are the files this group is built for.

The insurance group is led by partners Jim Davidson and Chris Morrison, supported by a defence and coverage bench that includes Joel Cormier, Tiffany Usher, Hudson Chalmers, Kathleen Lefebvre and Margaret Klassen. We act for insurers and for the insureds they appoint us to defend, and we advise insurers directly on coverage.

What distinguishes the practice is its courtroom and appellate depth. Many claims resolve on paper. The ones that do not are resolved on the strength of counsel who try cases and argue appeals, and our results at first instance are backed by an appellate practice that has shaped Canadian law in both tort liability and insurance.

Who We Act For

Counsel to the insurance industry

Our clients are institutions and the professionals who run their files. We are retained to defend claims, to resolve them efficiently, and to advise on the coverage questions that sit behind them. The common thread is exposure that justifies experienced counsel.

CLIENTS

Primary and excess insurers

We act for insurers across personal and commercial lines, defending the claims they assign and advising on the ones they question.

CLIENTS

Claims professionals and adjusters

We work the way a claims department does: early assessment, a defence plan and budget you approve, and reporting that lets you set reserves with confidence.

CLIENTS

Insureds appointed to us

When an insurer appoints us to defend its insured, that policyholder receives a trial-ready defence, with the duty owed to the insured fully respected.

CLIENTS

Other lawyers and firms

We are retained as counsel by other defence lawyers on coverage questions, complex defences and appeals, including matters referred from firms without an in-house appellate group.

Lines We Defend

What we defend

Our defence work spans personal and commercial lines. The matters we are most often retained on include the following. If a line is not listed, it does not mean we cannot assist, so please ask.

Liability

Commercial and general liability

Bodily injury and property damage claims under commercial general liability policies, defending insureds across a wide range of industries.

Motor Vehicle

Motor vehicle and bodily injury

Efficient, cost-effective defence of bodily-injury claims arising from motor vehicle accidents, including the interplay between tort claims and statutory accident benefits.

Premises

Occupiers' liability

Defence of slip, trip and fall claims on behalf of general liability policyholders and the institutional clients who insure them.

Property

Fire and property loss

Defence of commercial and residential fire and property loss claims, where insurers and adjusters apply close scrutiny to cause, origin and quantum.

Construction

Construction defects

Course-of-construction, defective work and related claims, including the coordination of multiple trades, sureties and insurers.

Project Risk

Wrap-up and builders risk

Wrap-up liability and builders risk exposures on large construction and development projects.

Products

Product liability

Defence of product liability and product-related property damage claims, including multi-defendant supply-chain disputes.

Professional

Professional negligence

Defence of professional negligence and errors and omissions claims brought against insured professionals.

Environmental

Environmental claims

Environmental loss and contamination claims, including historical exposures and disputes that turn on pollution wording.

Cyber

Cyber and privacy

Cyber, data-breach and privacy claims, an area of growing exposure for insurers across every line.

Class Actions

Class action defence

Defence of class proceedings, including environmental losses, large property claims and product liability.

Recovery

Subrogated recovery

Prosecution of subrogated claims on behalf of insurers seeking to recover from at-fault third parties after a significant loss.

Coverage

Coverage, before and after a claim

Before a defence is ever mounted, the first question is often whether the policy responds at all. Jim Davidson is regularly consulted by insurers and by other lawyers on exactly that question, including coverage for uninsured and underinsured losses. We give coverage opinions that are practical and timely, written so a claims professional can act on them.

Where coverage is genuinely in issue, we advise on the duty to defend and the duty to indemnify, on reservation of rights and non-waiver, and we litigate coverage and priority disputes when they cannot be resolved any other way. Because we also run the underlying defence, our coverage advice is grounded in how the claim is actually likely to unfold.

Coverage turns on the specific policy wording and the facts of the loss. The analysis is file-specific, and we say so plainly when a question is genuinely unsettled.

Our coverage work

  • Coverage opinions on new and developing claims
  • Duty to defend and duty to indemnify analysis
  • Reservation of rights and non-waiver agreements
  • Declaratory and coverage actions
  • Priority and "other insurance" disputes
  • Uninsured and underinsured exposure

Working With Insurers

Built for the way claims departments work

Outside counsel earns its place by making a file easier to manage, not harder. That means an honest read early, a defence run in proportion to the exposure, and no surprises along the way.

ONE

Early assessment and reserves

A candid view of liability, exposure and likely cost at the outset, so reserves are set on real information rather than optimism.

TWO

Proportionate, cost-effective defence

We staff and run files to the exposure in front of us. Efficiency here is not a slogan; it is how the cost of defence is kept proportionate to what is genuinely at stake.

THREE

Reporting you can rely on

Clear, timely reporting aligned to your file-handling guidelines, with a defence plan and budget you approve and no gaps between updates.

FOUR

Trial and appellate credibility

Files resolve on terms that reflect how they would end at trial. Counsel genuinely prepared to try the case, and to argue the appeal, change that calculus in your favour.

Appeals

Appeals are not an afterthought here

Insurance disputes do not always end at trial. An adverse judgment, a novel coverage ruling or a certification decision can put far more at stake on appeal than the original claim did. Davidson Cahill Morrison LLP runs its appeals in-house, and the same group that defends a file can carry it through the Divisional Court, the Court of Appeal for Ontario and, where it goes that far, the Supreme Court of Canada.

Chris Morrison has more than sixty reported decisions and has argued multi-million-dollar civil appeals, including the largest award of general damages for wrongful death in Canadian history. His work in the Court of Appeal and the Supreme Court of Canada has become part of the established law of tort liability and insurance. For an insurer, that means an appeal can be assessed honestly and argued by counsel who has been there before.

Appellate work

  • Court of Appeal for Ontario, for appellants and respondents
  • Divisional Court appeals and judicial review
  • Supreme Court of Canada appeals
  • Appellate strategy and opinions for other defence counsel
  • Appeals of certification and interlocutory rulings

From Instruction to Resolution

How a defence file runs with us

Every matter is different, but a defence file tends to move through the same stages. We tell you what to expect at each one, and where the cost and the exposure actually sit.

Intake and conflicts

We open the file quickly, clear conflicts, and confirm the scope of the retainer and exactly who we are instructed to act for.

Early assessment and reserves

A candid early view of liability, exposure and likely cost, so you can set reserves on real information from the start.

Defence plan and budget

A defence strategy and a budget you approve up front, staffed to the exposure and aligned to your file-handling guidelines.

Discovery and experts

Documentary and oral discovery, and the right experts, to test the claim and narrow what is genuinely in issue.

Resolution or trial

Most files resolve on terms that reflect their trial value. When a reasonable resolution is not available, we try them.

Appeal where it matters

If the result warrants it, the same group assesses and argues the appeal, without handing the file to anyone else.

Engagement

Instructed the way insurers prefer to instruct

We are used to working within the structures insurers and claims departments already use. Fee arrangements are flexible and agreed at the outset, whether that means a panel or instructed rate, a litigation budget, or task-based billing, and the defence is staffed and run in proportion to what is actually at stake.

We act from offices in Toronto, Huntsville and Bowmanville, and appear in courts and tribunals throughout Ontario.

  • Panel and instructed-rate arrangements
  • Litigation budgets and defence plans agreed up front
  • Reporting aligned to your file-handling guidelines
  • Staffing kept proportionate to the exposure
  • Coverage and defence handled within one group

Questions From Insurers and Counsel

Frequently asked questions

What insurance lines does the group defend?

We defend across personal and commercial lines: general and commercial liability, motor vehicle and bodily injury, occupiers' liability, fire and property loss, construction defects and wrap-up, product liability, professional negligence, environmental, cyber and privacy, and class proceedings. We also prosecute subrogated claims on behalf of insurers.

Will you act on a panel or instructed-rate basis?

Yes. We are used to working within insurers' panel arrangements, litigation budgets and file-handling guidelines, and we agree fee terms at the outset of each retainer.

Can you give a coverage opinion before a claim is in suit?

Yes. Jim Davidson is regularly consulted by insurers and other lawyers on coverage, including uninsured and underinsured losses. We provide practical, timely coverage opinions written so a claims professional can act on them.

Can one firm handle both the coverage question and the underlying defence?

Yes. Because we advise on coverage and run defences, our coverage analysis is grounded in how the claim is actually likely to unfold, and the two can be coordinated within one group. Where the duty to defend requires it, we address reservation of rights and any conflict at the outset.

If the case is appealed, who argues it?

We do. Appeals are run in-house by the same group, through the Divisional Court, the Court of Appeal for Ontario and, where necessary, the Supreme Court of Canada. Chris Morrison leads the firm's appellate work.

Do you act for both insurers and individuals, and how do you manage conflicts?

Across the firm, our lawyers act on both sides of insurance disputes, which sharpens the defence strategy we bring to an insurer's file. Conflicts are screened at intake, and the institutional clients of this group are defended by counsel retained to act for insurers.

Where are you located, and do you cover all of Ontario?

We act from offices in Toronto, Huntsville and Bowmanville, and appear in courts and tribunals throughout the province.

How do we refer a file or open a new matter?

Contact the insurance group directly. We will clear conflicts, confirm the scope of the retainer, and give you an early read on the file.
