Basic Principles of Contract Interpretation
This blog summarizes, at a very high level, the basic principles of contract interpretation.
The Goal – Reflect Intention of the Parties
To help the court find “an interpretation that reflects and promotes the intention of the parties at the time they entered into the contract.”
[Consolidated Bathurst Export Ltd. v. Mutual Boiler and Machinery Insurance Co.,  1 S.C.R. 888]
The Cardinal Rule – Intentions Are as Expressed in Written Document
“The court should give effect to the intentions of parties as expressed in their written document.”
[Manulife Bank of Canada v. Conlin,  3 S.C.R. 415]
The intent of the parties is determined by the words they used in the contract. The court focuses on the written contract and the words used by the parties in that contract.
[Eli Lilly & Co. v. Novopharm Ltd.,  2 S.C.R. 129]
The “Parol Evidence Rule” – Do not Consider Extrinsic Evidence If Words are Unambiguous
The court does not consider evidence extrinsic to the words used by the parties to the written contract if that document is clear and unambiguous on its face.
Give Effect to Entire Contract
A court must, if possible, give effect to all of the provisions in a contract.
[BG Checo International Ltd. v. British Columbia Hydro & Power Authority,  1 S.C.R. 12]
A court cannot “simply pick and choose clauses – or parts of clauses – without considering the contract as a whole.”
[ATCO Electric Ltd. v. Alberta (Energy and Utilities Board), 2004 ABCA 215]
Harmonize Apparently Conflicting Terms
In order to give effect to all provisions in the contract, it may be necessary to “strive to harmonize apparently conflicting terms in a contract.”
[369413 Alberta Ltd. v. Pocklington, 2000 ABCA 307]
Specific Terms Often Qualify More General Terms
In striving to harmonize apparently conflicting terms, the court’s interpretation will often read specific terms as qualifying more general terms, that is to say that “the terms may be reconciled by taking the parties to have intended the scope of the general term to not extend to the subject matter of the specific term.”
Court May Consider Absence of Words in Contract
Although a court is not to consider evidence extrinsic to the words used by the parties if the written contract is clear and unambiguous on its face, a court may consider the absence of words in the contract.
[Geoffrey L. Moore v. Manitoba Motor League (c.o.b.) CAA Manitoba (2003), 10 R.P.R. (4th) 1 (Man C.A.)]
Court May Consider Background
The court may also consider the surrounding circumstances or the relevant background against which the contract was concluded.
Do Not Consider Crossed Out Words
Crossed out (or struck) words should not be considered in interpreting a contract. For example, in Indian Moylbdenum Ltd. v. The King,  3 D.L.R. 497 (S.C.C.), it was held that “words deleted by the drawing of a line through them, and this deletion initialed by the parties, cannot be looked at.”
Does an Ambiguity Exist?
An ambiguity in the words in the document arises when a contract is “reasonably susceptible of more than one meaning.”
[Hi-Tech Group Inc. v. Sears Canada Inc. (2001), 52 O.R. (3d) 97 (C.A.)]
However, mere difficulty in interpreting a contract is not the same as ambiguity.
[Northwestern Mechanical Installations Ltd. v. Yukon Construction Co. (1982), 37 A.R. 132.]
If Ambiguous, Courts May Apply Consider Extrinsic Evidence - Exception to Parol Evidence Rule
One exception to the parol evidence rule arises in the event of ambiguity in the language of the contract. In such instances, extrinsic evidence is admitted to clarify the meaning of the ambiguous words or phrases.
[United Brotherhood of Carpenters and Joiners of America, Local 579 v. Bradco Construction Ltd.,  2 S.C.R. 316]
If Ambiguous, Promote a Sensible Commercial Result
In the face of ambiguity, the interpretation promoting a sensible commercial result is to be preferred.
If Ambiguous, Court May Apply Contra Preferendum Doctrine
In addition, the presence of ambiguity allows a court to apply the contra preferentum doctrine and interpret an ambiguous provision against the party who drafted it.
