If It Is Possible That An Insurance Company Will Need to Pay Out Under the Coverage of An Insurance Policy Is a Lawsuit Is Successful, Then the Insurance Company Is Also Required to Provide and Pay For the Legal Defence of the Lawsuit.
A Helpful Guide For How to Determine Whether An Insurer Owes a Duty to Defend a Legal Case On Behalf of An Insured
Fighting a lawsuit can be an expensive proposition in both time and money as well as highly stressful. In addition to the stress of fighting the case, the stress of possibly losing the case is especially troubling. Accordingly, an insured person will be concerned for both insurance coverage to protect against the possibly of losing the case as well as concern for the time, costs, and efforts, of defending the case. Generally, where an insurance policy is in place to cover the liability that may arise if the lawsuit is proven, then the insurance is also obligated to providing a defence of the lawsuit.
As said in the case of Progressive Homes Ltd. v. Lombard General Insurance Co. of Canada, 2010 SCC 33 (CanLII),  2 SCR 245, the duty to defend an insured is dependent on whether the insurance coverage prescribed by the policy would be triggered if the liability claim brought against the insured person is successfully proven. Where the policy would respond to provide coverage if the lawsuit is successful, the policy must provide a defence. This was explicitly stated by the Supreme Court in Progressive Homes where it was said:
 An insurer is required to defend a claim where the facts alleged in the pleadings, if proven to be true, would require the insurer to indemnify the insured for the claim (Nichols v. American Home Assurance Co., 1990 CanLII 144 (SCC),  1 S.C.R. 801, at pp. 810-11; Monenco Ltd. v. Commonwealth Insurance Co., 2001 SCC 49,  2 S.C.R. 699, at para. 28; Jesuit Fathers of Upper Canada v. Guardian Insurance Co. of Canada, 2006 SCC 21,  1 S.C.R. 744, at paras. 54-55). It is irrelevant whether the allegations in the pleadings can be proven in evidence. That is to say, the duty to defend is not dependent on the insured actually being liable and the insurer actually being required to indemnify. What is required is the mere possibility that a claim falls within the insurance policy. Where it is clear that the claim falls outside the policy, either because it does not come within the initial grant of coverage or is excluded by an exclusion clause, there will be no duty to defend (see Nichols, at p. 810; Monenco, at para. 29).
 In examining the pleadings to determine whether the claims fall within the scope of coverage, the parties to the insurance contract are not bound by the labels selected by the plaintiff (Non-Marine Underwriters, Lloyd’s of London v. Scalera, 2000 SCC 24,  1 S.C.R. 551, at paras. 79 and 81). The use or absence of a particular term will not determine whether the duty to defend arises. What is determinative is the true nature or the substance of the claim (Scalera, at para. 79; Monenco, at para. 35; Nichols, at p. 810).
As stated within Progressive Homes when reviewing whether an insurance policy might be triggered, it is necessary to review the context of the allegations rather than the express words of the allegations. For example, where allegations may use legal terminologies such as 'breach of contract', which is generally excluded by an insurance policy, the context of the allegations may involve negligence which may be included by an insurance policy even if the word negligence is absent. For example, the lawsuit may allege that, "the Defendant breached the contract by failing to perform in the diligent manner that would be usual to a reasonable person"; and thereby the allegations sound in negligence.
The duty to defend falls to be determined on the basis of the pleadings in the underlined action or actions and the coverage provisions of the policy or policies of insurance. The general principle has been stated as follows:
The duty to defend is broader than the duty to indemnify, and the mere possibility that a claim within the policy coverage provisions will succeed is sufficient to engage the insurer's duty to defend.
(St. Paul Fire & Marine Insurance Co. v. Durabla Canada Ltd. (July 10, 1996) Ontario Court of Appeal [now reported 1996 CanLII 494 (ON CA), 29 O.R. (3d) 737 at p. 739, 137 D.L.R. (4th) 126]; Bacon v. McBride (1984), 1984 CanLII 692 (BC SC), 5 C.C.L.I. 146 at p. 151, 51 B.C.L.R. 228 (S.C.).
An insurer owes the duty to defend where an insurance policy provides coverage for the liability that may arise if the legal action brought is successfully proven.
