Module 1: The Modern Approach

The single dominant framework in Canadian statutory interpretation. Stated in Rizzo & Rizzo Shoes [1998] 1 SCR 27 at para 21, adopting Elmer Driedger:

"Today there is only one principle or approach, namely, the words of an Act are to be read in their entire context and in their grammatical and ordinary sense harmoniously with the scheme of the Act, the object of the Act, and the intention of Parliament."

Reaffirmed as the governing approach in every major statutory interpretation case since, including Vavilov 2019 SCC 65.

The Three Elements

Every interpretive analysis addresses:

1. TEXT — the words themselves, in grammatical and ordinary sense
2. CONTEXT — the whole Act, related provisions, related statutes
3. PURPOSE — the object of the Act, the intention behind it

These are not sequential steps to be tried in order. They are elements that must be read TOGETHER, harmoniously. The correct interpretation is the one that fits all three.

The Test in Practice

For any interpretive question:

TEXT: What do the words say in their ordinary meaning?
CONTEXT: What does the surrounding statutory scheme suggest?
PURPOSE: What is the object of this Act, and what interpretation
         advances it?
HARMONY: Which interpretation makes text, context, and purpose fit
         together?

An interpretation that satisfies one element but violates another is usually wrong. Look for the interpretation that harmonizes all three.

Module 2: Text

The ordinary meaning of the words is the starting point.

The Ordinary Meaning

The meaning a reasonable person would give the words in their grammatical and ordinary sense. Not necessarily the dictionary definition (though dictionaries can help).

The Plain Meaning "Rule"

Historically, the plain meaning rule said: if the words are plain, apply them without further analysis. This "rule" no longer stands on its own. Under the modern approach, the plain meaning is one input, but must be harmonized with context and purpose.

When Text Alone Is Enough

Where text, context, and purpose all point the same way — and the words are clear — text-based reasoning may resolve the question quickly. But even then, the interpreter should verify context and purpose confirm the reading.

When Text Alone Is Not Enough

• Ambiguous words (multiple possible meanings)
• Words that produce absurd results if read literally
• Words where a technical meaning differs from ordinary meaning
• Words in a specialized legislative context

The Ordinary vs Technical Meaning

Statutes sometimes use words in a technical or defined sense different from ordinary meaning. Check for definitions in the Act (Module 8) and for context suggesting a technical meaning.

---

Module 3: Context

The whole Act read together.

Internal Context

• Neighbouring provisions — subsections and adjacent sections often colour the meaning
• The section as a whole — the provision must be read in its section
• The part or division — sometimes statutes are organized into parts with distinct purposes
• Marginal notes, headings — indicative but not definitive
• The Act as a whole — every provision is presumed to have a place in the scheme
• Definitions section — controls the meaning of defined terms

External Context

• Related enactments — often statutes must be read alongside others (e.g. the RTA alongside the Manufactured Home Park Tenancy Act, the ATA, or applicable regulations)
• Predecessor legislation — the statute's history may illuminate
• International agreements — where the statute implements an international commitment

The Scheme of the Act

The overall structure — what the Act does, how its provisions relate, what problem it solves. Every interpretation must fit this scheme.

---

Module 4: Purpose

Every statute has a purpose. Purposive interpretation gives effect to that purpose.

Sources of Purpose

• Preamble — where present, states purpose explicitly
• Purpose section — modern statutes often have a section stating purposes
• Legislative history — debate, committee reports (Module 7)
• Prior enactments — what problem was Parliament fixing?
• Case law — courts often articulate statute purposes

Purposive Interpretation in Action

Where text is ambiguous, the interpretation that better advances the statute's purpose is preferred. Where text and purpose diverge, the question is whether the divergence can be reconciled or whether text must give way to purpose (rarely).

Remedial Statutes

Statutes remedying a defect or protecting a vulnerable group are read liberally to advance the remedy. The Interpretation Acts (federal and provincial) codify this:

• Federal Interpretation Act s.12: "Every enactment is deemed remedial, and shall be given such fair, large and liberal construction and interpretation as best ensures the attainment of its objects."
• Similar provisions in provincial Interpretation Acts.

The RTA Specifically

The Residential Tenancy Act is remedial legislation. Its purpose includes protection of tenants and orderly regulation of landlord- tenant relationships. This attracts:

• Liberal interpretation of protections
• Strict interpretation of provisions that permit ending a tenancy
• Purposive resolution of ambiguities

Landlords and tenants should both be aware of this interpretive lean.

Module 5: Interpretive Presumptions

Default rules that apply unless displaced.

Presumption Against Absurdity

The legislature is presumed not to intend absurd results. Where an interpretation leads to consequences that reasonable persons would regard as unjust, unworkable, or absurd, an alternative interpretation is preferred.

Presumption of Consistent Meaning

Words used more than once in the same Act are presumed to have the same meaning throughout. Different words are presumed to have different meanings.

Presumption Against Redundancy

Every word in a statute is presumed to have meaning. An interpretation that renders words superfluous is disfavoured.

Presumption Against Retroactivity

Statutes are presumed to apply prospectively only. Retroactive application requires clear language.

Distinguished from:

• Retrospective operation — new law affects the consequences of past facts (permitted more freely)
• Prospective operation — new law affects future facts (the default)

Presumption in Favour of Liberty

Ambiguous criminal or penal provisions are construed narrowly, in favour of the accused / affected person. Historically stated as the rule of lenity.

Presumption Against Interference with Vested Rights

Statutes are presumed not to interfere with vested rights unless clearly stated.

Presumption of Constitutionality

Where two interpretations are available, one constitutional and one not, the constitutional interpretation is preferred.

Presumption Against Extraterritorial Application

Statutes are presumed not to apply outside the enacting jurisdiction unless stated.

Presumption of Compliance with International Law

Ambiguous provisions are presumed to comply with Canada's international obligations.

Presumption of Consistency with Common Law

Statutes are presumed not to alter the common law more than necessary to achieve their purpose.

Presumption Against Crown Liability

The Crown is presumed not to be bound by a statute unless the statute expressly or by necessary implication binds it. Modified by Crown Liability legislation for most modern purposes.

Module 6: Interpretive Rules

Latin-labelled rules that are useful heuristics, not commandments.

Ejusdem Generis (of the same kind)

Where a general term follows a list of specific terms, the general term is limited to things of the same kind as the specific terms.

Example: "cars, trucks, motorcycles, and other vehicles" — "other vehicles" limited to motorized road vehicles.

Application requires:

• A genus identifiable from the specific terms
• The general term following the specifics

Expressio Unius Est Exclusio Alterius (the express mention of one is the exclusion of others)

Where certain things are expressly mentioned, others of the same class are impliedly excluded.

Example: A statute listing categories that qualify implicitly excludes categories not listed.

Application is cautious — silence is not always exclusion. Consider whether the omission was intentional or merely a drafting shortcut.

Noscitur a Sociis (known by its associates)

A word's meaning is coloured by the words around it. Vague or general words in a series are interpreted in light of specific companions.

Generalia Specialibus Non Derogant (general terms do not derogate from specific terms)

Where a general provision conflicts with a specific one, the specific prevails. Applied where two provisions in the same or different Acts are apparently inconsistent.

Golden Rule / Absurdity Rule

Now largely absorbed into the modern approach: read text in context and purpose, avoiding absurd results.

Mischief Rule

A historical formulation asking what mischief the statute was designed to remedy. Now absorbed into purposive interpretation.

---

Module 7: Extrinsic Aids

Sources beyond the statute itself, used to illuminate meaning.

Hansard / Legislative Debates

Records of parliamentary debate. Admissible but of limited weight — individual statements are not necessarily the legislature's view.

Higher weight for:

• Statements by the sponsoring minister
• Statements addressing the specific provision
• Statements not contradicted in later debate

Committee Reports

Reports of legislative committees studying the bill. Often more detailed than debates and may explain specific provisions.

Prior Enactments

The predecessor legislation the statute replaced. Differences between predecessor and current text may be revealing.

Related Legislation

Statutes on related subjects, or predecessor statutes, may illuminate.

International Agreements

Where the statute implements an international agreement, the agreement may be consulted.

Case Law Interpreting Predecessors

Cases interpreting the predecessor legislation may inform current interpretation, though Parliament's changes must be respected.

Academic Commentary

Textbooks and articles may be cited. Weight varies with authority of the author and treatment.

The Bilingual Statute (Federal)

Both English and French versions are equally authoritative. Where they differ, principles of shared meaning apply.

---

Module 8: Definitions and Interpretive Provisions

Definition Sections

Most statutes contain a definitions section (usually s.1 or s.2). Terms defined there have their statutory meaning wherever used in the Act, unless context requires otherwise.

Definition Types

• "Means" — an exhaustive definition
• "Includes" — a non-exhaustive definition, extending or specifying the ordinary meaning
• "Does not include" — an express exclusion from what would otherwise be included

The choice of "means" vs "includes" matters. "Includes" invites the ordinary meaning plus the specified additions; "means" limits to what is specified.

The Interpretation Act

Both federal and provincial jurisdictions have Interpretation Acts providing default rules. Selected common provisions:

• Every enactment is remedial (federal s.12)
• Singular includes plural, plural includes singular
• Masculine includes feminine (older provisions; modern drafting is gender-neutral)
• Reference to a person includes a corporation (typically)
• Rules for computing time
• Rules for repeal and re-enactment

Consult the specific Interpretation Act for the jurisdiction.

Interpretive Provisions Within the Statute

Some statutes contain interpretive sections beyond definitions — rules about how the Act is to be applied. These are binding within the Act.

Example: RTA s.5 states the Act's rules apply despite any agreement or waiver to the contrary. This is an interpretive rule with substantive consequence.

---

Module 9: Bilingual Interpretation (Federal Statutes)

Equal Authority

Under s.18 of the Charter and the Official Languages Act, both English and French versions of federal statutes are equally authoritative.

The Shared Meaning Rule

Where versions differ:

1. Identify the shared meaning if any
2. Where one version is broader and the other narrower, the narrower is often preferred as the shared meaning
3. Where the versions cannot be reconciled, the interpretation consistent with the Act's purpose is preferred

Practical Application

For interpretive arguments on federal statutes, check both versions. Where the versions differ, this may be significant.

Provincial statutes generally have one authoritative version, though some provinces provide bilingual versions.

Module 10: Interpretation in Administrative Context

Deference to Administrative Interpretation

Post-Vavilov, an administrative decision-maker's interpretation of its home statute is reviewed on a reasonableness standard (subject to exceptions).

This means:

• The decision-maker's interpretation need not be correct
• It must be reasonable
• The reviewing court is not to impose its own interpretation absent unreasonableness

But: the reasonableness analysis requires the decision-maker's interpretation to be one that could result from applying the modern approach to statutory interpretation. Interpretations that ignore text, context, or purpose are unreasonable.

The RTB Specifically

The RTB interprets the RTA. Its interpretations receive deference on judicial review under ATA s.58 (patent unreasonableness for factual findings and interpretation of the RTA).

However: patent unreasonableness is the highest deference, but not absolute. An interpretation that:

• Ignores clear text
• Ignores the Act's remedial purpose
• Produces absurd results
• Fails to apply the modern approach

...may be patently unreasonable.

Building Interpretation Arguments in JR

For a JR based on statutory interpretation:

□ Identify the specific provision at issue
□ State the modern approach
□ Analyze text — grammatical and ordinary meaning
□ Analyze context — internal and external
□ Analyze purpose — remedial character of the RTA
□ Show that the arbitrator's interpretation fails one or more elements
□ Argue that the correct interpretation is your position
□ Show that no reasonable interpretation could reach the arbitrator's
  result (for patent unreasonableness threshold)

Not every interpretive disagreement is patent unreasonableness. Reserve the argument for interpretations that genuinely fail the modern approach, not merely for interpretations you disagree with.
