The parties agree that the governing principles of
interpretation applicable to insurance policies are those summarized
by Rothstein J. in Progressive Homes [2010 SCC 33, [2010] 2 SCR
245]. The primary interpretive principle is that where the language of
the insurance policy is unambiguous, effect should be given to that
clear language, reading the contract as a whole: para. 22, citing
Non-Marine Underwriters, Lloyd’s of London v. Scalera, 2000 SCC
24, [2000] 1 S.C.R. 551, at para. 71.
[50]
Where, however, the policy’s language is
ambiguous, general rules of contract construction must be employed
to resolve that ambiguity. These rules include that the interpretation
should be consistent with the reasonable expectations of the parties,
as long as that interpretation is supported by the language of the
policy; it should not give rise to results that are unrealistic or that the
parties would not have contemplated in the commercial atmosphere
in which the insurance policy was contracted, and it should be
consistent with the interpretations of similar insurance policies. See
Progressive Homes, at para. 23, citing Scalera, at para. 71; Gibbens
[2009 SCC 59, [2009] 3 SCR 605], at paras. 26-27; and
Consolidated-Bathurst Export Ltd. v. Mutual Boiler and Machinery
Insurance Co., [1980] 1 S.C.R. 888, at pp. 900-902.

Discussing the reasonable expectation of the parties, Wagner J. said:
[65]
Parties’ reasonable expectations with respect to the
meaning of a contractual provision can often be gleaned from the
circumstances surrounding the contract’s formation: Sattva, at paras.
46-47. However, as discussed above, there is no factual matrix here
that would assist in ascertaining the parties’ understanding of and
intent regarding the Exclusion Clause. The Policy is a standard form
contract. And, as the Court of Appeal noted at para. 15 of its reasons,
there is no evidence that the parties gave any thought to the cleaning
of the windows, the relationship of faulty workmanship to resulting
damage, or anything else that would help in determining their
reasonable expectations.

Therefore, in my view, the purpose behind builders’
risk policies is crucial in determining the parties’ reasonable
expectations as to the meaning of the Exclusion Clause. In a nutshell,
the purpose of these polices is to provide broad coverage for
construction projects, which are singularly susceptible to accidents
and errors. This broad coverage – in exchange for relatively high
premiums – provides certainty, stability, and peace of mind. It
ensures construction projects do not grind to a halt because of
disputes and potential litigation about liability for replacement or
repair amongst the various contractors involved. In my view, the
purpose of broad coverage in the construction context is furthered by
