Nature of Contracts
Contract = legally enforceable agreement; distinguishes from a mere promise or morally-binding “comfort letter”
Primary duty: perform promises ⇒ breach triggers secondary duty: \text{damages} (mirrors torts: duty not to harm ⇒ damages if breached)
Tort vs Contract (risk & remedial lens)
Tort duties imposed by law; apply irrespective of relationships; compensation looks backward (“as if tort never occurred”)
Contract duties voluntary; enforceable only by parties (privity); compensation looks forward (“as if contract performed”)
Contractual risk ≈ predictable & limitable; tort risk often surprises and may exceed ability to pay
Essential Elements
Intention to create legal relations
Objective test at formation moment: would reasonable person think parties meant legal consequences?
Presumptions (rebuttable): commercial dealings ⇒ intent; domestic/social ⇒ no intent
Meeting of the Minds (Offer + Acceptance)
Offer: unequivocal willingness to contract on stated terms
Acceptance: unqualified assent; creates contract instantly
Consideration: exchange of value (promise ↔ promise, act ↔ promise)
Capacity & Legality
Capacity issues: minors (<18 yrs in CAN), mental infirmity, intoxication etc.
Offer Mechanics
Must be communicated as an offer (undelivered letter or mistaken context ≠ offer)
Distinguish “invitation to treat” (displays, ads, catalogues) ⇒ responder becomes offeror
Life-cycle: Creation → (acceptance) OR termination via revocation, lapse, death/insanity, rejection, counter-offer
Revocation rules
Free until communicated; ineffective until reasonably brought to offeree’s attention
Special cases: Firm Offer (gratuitous; unenforceable unless under seal); Option (supported by consideration or seal; binding)
Tendering
Contract A (bidding fairness) forms when bid submitted; Contract B (performance) forms upon award
Bidders barred from revoking after closing; owners must select fairly
Acceptance Nuances
Methods: words, conduct, handshake; silence alone never acceptance unless prior agreement
Distance communications
Instantaneous (phone, email, text): effective when & where received
Non-instantaneous (mail, some faxes/emails): “postal rule” ⇒ effective when & where sent, even if lost; offeror can displace by stipulating
Unilateral contracts: offer invites performance (e.g., lost-cat reward). Contract arises only on full performance; offer can be revoked before completion yet unfair revocations discouraged (Carlill v Carbolic Smoke Ball)
Nature & Functions
Ensures reciprocity; each side gives a benefit or suffers detriment
Must “move from promisor”, but need not flow to other party (e.g., pay 5000 to your brother if you transfer car to my sister)
Sufficiency vs Adequacy
Any objective value counts (peppercorn, 1); courts ignore fairness of bargain
Love & affection ≠ consideration
Forbearance to sue is valid if underlying claim is bona fide (even if ultimately invalid), otherwise not
Temporal & Pre-existing Issues
Past consideration = no consideration (cannot bargain for what’s already done)
Pre-existing duties
Public duty (police, fire): no new consideration
Duty owed to third party: yes (new benefit to promisee)
Same duty to same party: no (risk of economic duress); contract amendments require fresh consideration (e.g., earlier completion, additional work)
Debt Compromises
Part-payment of debt generally unenforceable without new consideration, seal, statutory variation or promissory estoppel
Promises Without Consideration
Seal: red wafer or printed mark next to signature substitutes for consideration; historic mechanism, still common in guarantees/confidentiality agreements
Promissory Estoppel (shield not sword)
Elements: existing legal relationship; clear promise not to enforce rights; reasonable reliance; innocent conduct by promisee
Effect: suspends/varies rights; can be withdrawn prospectively with notice
Privity & Exceptions
Only contracting parties may sue/be sued
Exceptions
Assignment (equitable, statutory, operation of law) transfers rights
Trusts: beneficiary can enforce
Statutory rights (e.g., life-insurance beneficiaries)
Employment “Himalaya clauses” protect employees if: intended & acting within scope
Assignment rules
Equitable: oral/written, notice advisable, subject to equities
Statutory: written, absolute, notice mandatory ⇒ assignee sues in own name
Obligations cannot generally be assigned; vicarious performance allowed
Categories of Negotiation Statements
Puffery: sales talk, no legal effect
Representation: induces contract; actionable if misrepresentation (false fact)
Term: becomes contractual promise; breach sounds in contract
Misrepresentation Elements
False statement of existing fact (not opinion, future intent, law) that induces contract; relied upon; damages ensue
Silence generally allowed but duty arises if previous statement now false, half-truth, utmost good faith contract, fiduciary relationship, statute compels disclosure, or active concealment
Types & Remedies
Innocent: rescission (+restitution) only
Negligent: rescission + damages in tort of negligence
Fraudulent: rescission + damages in tort of deceit; punitive possible
Rescission barred if: impossibility of restitution, third-party rights, affirmation, lapse of time
Express Terms
Evidence: written terms subject to parol evidence rule (can’t vary clear writing except for rectification, non-formation, ambiguity, incompleteness, collateral contract)
Interpretation tools: literal, contextual, golden rule; contra proferentem for ambiguities
Implied Terms
By court: business efficacy, obviousness, usage/custom, previous dealings, legal character
By statute: Sale of Goods, consumer laws; some mandatory
Standard Form & Boilerplate
Reduce transaction costs; risk of imbalance
Exclusion/Waiver clauses: must be clear, reasonably brought to attention, accepted (signature/initials), not unconscionable; onerous terms require high notice
Boilerplate types: force majeure, confidentiality, arbitration, jurisdiction, entire agreement
Plain language movement improves clarity; reduces disputes & training costs
Modes
Performance (incl. tender of payment/performance; time of essence provisions)
Agreement: option to terminate; conditions subsequent/precedent; rescission; accord & satisfaction (new consideration); release (seal); variation (minor change + consideration); novation; waiver (promissory estoppel-like)
Operation of Law: frustration, limitation periods, bankruptcy
Breach: failure of condition/warranty/intermediate term; anticipatory breach; defective performance; deviation; self-induced impossibility
Term Classification & Remedies
Condition: serious; innocent party may terminate + damages
Warranty: minor; only damages
Intermediate: “wait-and-see”
Legal (Monetary)
Expectation (benefit of bargain) = \text{expected gains} - \text{expected costs}; subject to causation, remoteness, mitigation; issues with cost-of-cure vs diminished value
Reliance (wasted expenditure); bar if contract inherently loss-making
Account of profits (disgorgement)
Nominal (\le 10) symbolic
Liquidated damages (genuine pre-estimate) enforceable; penalty unenforceable
Punitive damages: rare; require independent actionable wrong + egregious conduct
Equitable
Specific performance: unique goods/land; prerequisites – inadequacy of damages, mutuality, no constant supervision, not personal services, claimant “clean hands”
Injunction: order to refrain from breach; broader availability, less intrusive
Unjust Enrichment
Elements: \text{enrichment} of defendant, corresponding deprivation, no juristic reason ⇒ remedy is restitution (value, not necessarily original asset)
Real Property Scope
Traditional “carrot” (centre → sky); modern: reasonable depth & height
Fixtures: chattels sufficiently affixed become part of land (tenant’s fixture removable w/o damage & within reasonable time)
Estates
Fee Simple: largest bundle; subject to zoning, tort duties, expropriation (forced sale for public purpose with compensation)
Life Estate: exclusive possession for life; no right to devise; liable for waste; reversion/remainder interests specified
Leasehold: exclusive possession for definite period; forms via contract
Shared Ownership
Joint Tenancy: identical interests, right of survivorship ⇒ last owner takes all; severed by sale, agreement, partition
Tenancy-in-common: undivided but unequal shares; no survivorship ⇒ passes via will/intestacy; common in business succession
Condominium/Strata: fee simple in unit + co-ownership of common property; managed via strata corp & fees
Non-Possessory Interests
Easement: right to use neighbour’s land; dominant/servient; created express, implied, prescription, statute; positive/negative
Restrictive Covenant: promise limiting servient’s land use; must benefit dominant land; runs with land if negative
Mineral lease / Profit à prendre: right to extract resources; may require separate surface lease
Leases
Writing required unless \le 3 years (varies)
Tenancies: fixed, periodic, at will, at sufferance
Termination options: consent, assignment (entire term), sublease (less than full term), early termination clauses
Commercial lease covenants: rent (gross/net), quiet enjoyment, repair/maintenance allocation, taxes, insurance; remedies include eviction, distress, damages; mitigation duty may differ by region
Residential leases: heavily regulated (rent control, repair obligations, no distress, landlord must mitigate)
Risk: lease vs purchase analysis (cost, cash flow, obligations, investment, flexibility, control, market changes)
Indigenous Land Interests
Aboriginal title (exclusive); Aboriginal & treaty rights; reserve lands, impact-benefit agreements; modern treaties create varied estates (fee simple, land code)
Registration Systems
Registry (deeds): chain of title search; buyer bears risk; priority by registration time unless notice/value issues; title insurance common
Land Titles (Torrens): indefeasible title certificate; mirror, curtain, insurance principles; emerging “deferred indefeasibility” to curb identity/mortgage fraud
Unregistered Interests: short leases, prescriptive easements, public utilities, tax liens, writs of execution
Purchase Process
Risk management team: agent, lawyer, appraiser, surveyor, inspector, environmental auditor
Agreement of Purchase & Sale often conditional precedent (financing, zoning, inspection)
Closing: remove conditions, adjust pre-payments, transfer deed/transfer form; remedies: damages, specific performance (land unique), purchaser/vendor liens
Mortgage Fundamentals
Mortgage = security interest + loan covenant
Parties: mortgagor (borrower), mortgagee (lender)
Systems: Registry → title transfers to mortgagee; Land Titles → charge registered, title stays with mortgagor
Equity of Redemption: mortgagor’s residual right to redeem even after default; multiple mortgages possible (“redeem up, foreclose down”) – priority by registration
Default Remedies
Sue on covenant (personal liability) – barred in some western provinces for residential property
Possession (rare; lender wants not mud)
Foreclosure (cuts equity & junior liens; harsh; less used)
Sale (judicial or power of sale) – proceeds distributed by priority; deficiency judgment may follow unless barred
Personal Property Categories
Tangible vs intangible; acquisition via purchase, gift, finding, creation; loss via sale, destruction, abandonment, becoming fixture
Bailment
Temporary transfer of possession & control with obligation to return; distinguishes licence (no transfer of control)
Duties
Bailor: deliver safe goods, warn of defects, pay agreed charges; bailee may assert lien/right of sale for unpaid charges
Bailee: reasonable care (higher if paid or valuable/fragile; lower if gratuitous); burden of proof shifts – bailee must disprove negligence once loss shown; common carriers under strict liability (war, act-of-God etc. as defences)
Sub-bailment: bailee entrusts goods to third party; requires bailor’s consent (express/implied); sub-bailee owes care & possibly suable by owner
Insurance Principles
Liability (third-party) vs property (first-party) coverage
Indemnity: never profit; insurable interest required; over-insurance ⇒ contribution; under-insurance ⇒ co-insurance clause proportion formula \frac{\text{coverage}}{\text{required}} \times \text{loss}$$
Subrogation: insurer, after paying, stands in the insured’s shoes against the wrongdoer
Business-specific covers: business interruption, hacker, key-person, life/health/disability, fidelity & surety bonds
Why is a “firm offer” label counter-intuitive? Because it suggests stability yet is actually a gratuitous promise lacking consideration and thus revocable unless sealed.
Be cautious when giving contractual indulgences—without seal or estoppel you may forfeit legal rights.
Do you understand what rights you waive by clicking “I Agree” on digital contracts?
Distinguish contractual conditions vs warranties – ask if breach deprives substantial benefit.
Drafting liquidated damages: must be genuine pre-estimate, not punitive; align with risk profile.
Tenant can only sub-lease what they possess: a subtenant’s rights limited by head lease.
Mortgage mantra: “foreclose down (senior to junior interests), redeem up (junior pays senior to save equity)”.
Insurance & vicarious liability: insurer may subrogate against negligent employee unless policy or employment law bars.
