Can You Sue Someone for Breach of Contract in Alberta?

Can You Sue Someone for Breach of Contract in Alberta?

Short answer: yes, you can sue someone for breach of contract in Alberta if there was a valid agreement, the other party failed to do what they promised, and you suffered a loss or are entitled to a legal remedy.

But not every broken promise is a lawsuit.

A breach of contract claim depends on what the agreement actually required, whether the other party failed to perform, whether you did what you were required to do, and what loss resulted.

The important point is simple:

A contract dispute is not just about whether someone acted unfairly. It is about what was agreed, what was breached and what remedy the law provides.

What Is a Breach of Contract?

A breach of contract happens when one party fails to do something required by the agreement.

Examples may include:

• failing to pay money owed;

• failing to deliver goods;

• failing to complete work;

• delivering defective work;

• missing a required deadline;

• refusing to close a real estate transaction;

• failing to provide services;

• terminating an agreement improperly;

• failing to meet performance standards;

• disclosing confidential information;

• violating a non-solicitation or non-competition clause;

• failing to return property;

• or doing something the contract prohibited.

The breach may be obvious.

For example, one party agreed to pay $25,000 by a specific date and did not pay.

Other cases are more complicated.

For example, the parties may disagree about the scope of work, the quality of performance, whether payment was due, whether a deadline was essential, or whether the contract was properly terminated.

What Do You Need to Prove?

A breach of contract claim usually requires proof of several basic things.

You generally need to show:

• there was a contract;

• the contract had terms that can be identified;

• you performed your obligations or had a valid reason not to;

• the other party breached the contract;

• the breach caused loss or gives rise to a remedy; and

• the amount or remedy claimed is supported by evidence.

The practical rule is simple:

You need more than frustration or disappointment. You need evidence of the agreement, the breach and the loss.

Does the Contract Have to Be in Writing?

Not always.

Contracts can be written, oral or partly written and partly oral.

A contract may be found in:

• a signed agreement;

• emails;

• text messages;

• invoices;

• purchase orders;

• quotes or estimates;

• terms and conditions;

• conduct between the parties;

• verbal promises;

• or a combination of documents and actions.

That said, written contracts are usually easier to prove.

Oral agreements can be enforceable, but disputes are harder when the parties disagree about what was said.

The practical point is this:

The less written evidence you have, the more important surrounding evidence becomes.

What Makes a Contract Valid?

A valid contract usually requires the basic elements of agreement.

These often include:

• an offer;

• acceptance;

• consideration, meaning something of value exchanged;

• certainty of essential terms;

• intention to create legal relations; and

• parties with legal capacity to contract.

In plain language, the court needs to be able to determine what the parties agreed to.

If the alleged agreement is too vague, incomplete or uncertain, it may be difficult to enforce.

For example, a statement like “we will work something out later” may not be enough.

But an agreement that identifies the work, price, parties and timing may be enforceable even if it was not drafted perfectly.

Common Types of Breach of Contract Claims

Breach of contract claims can arise in many situations.

Common examples include:

• unpaid invoices;

• construction disputes;

• renovation disputes;

• real estate purchase disputes;

• failed business transactions;

• service agreement disputes;

• loan repayment disputes;

• shareholder or partnership disputes;

• equipment sale disputes;

• employment contract disputes;

• commercial lease disputes;

• supply agreement disputes;

• professional service disputes;

• purchase and sale disputes;

• and disputes over termination clauses.

The legal principles may be similar, but the facts and contract terms matter.

A construction contract dispute will not be analyzed exactly the same way as a loan agreement, employment contract or real estate purchase contract.

What If the Other Party Says There Was No Contract?

That is common.

A defendant may argue:

• there was no final agreement;

• the parties were still negotiating;

• important terms were never agreed;

• the person who signed had no authority;

• the agreement was conditional;

• the contract was varied later;

• the contract was cancelled;

• the contract was too uncertain;

• or the agreement was not intended to be legally binding.

Evidence becomes critical.

Helpful evidence may include:

• signed documents;

• email chains;

• text messages;

• payment records;

• invoices;

• delivery records;

• meeting notes;

• drafts exchanged between the parties;

• witness evidence;

• and conduct showing both sides acted as if there was a deal.

The practical rule is simple:

If the other side denies the contract, the first fight may be about proving the agreement existed at all.

What If You Did Not Have a Formal Written Agreement?

You may still have a claim.

Many business and personal agreements are made without a formal contract.

For example:

• a contractor agrees by text to complete work for a price;

• a customer approves a quote by email;

• a business orders goods and accepts delivery;

• a borrower promises to repay money;

• parties agree orally to provide services;

• or someone performs work after the other party asks them to proceed.

The challenge is proving the terms.

Important questions include:

• What exactly was promised?

• What price was agreed?

• When was performance due?

• What quality or standard was required?

• Were there conditions?

• Did the other side accept the work or goods?

• Was payment made in part?

• Were invoices sent and not disputed?

• Did the parties act consistently with an agreement?

The practical point is this:

An informal contract can still be a contract, but evidence matters more.

What If the Contract Was Changed Later?

Contracts are often changed after they are signed.

The parties may agree to:

• extend deadlines;

• change the price;

• add work;

• remove work;

• accept partial performance;

• change payment terms;

• delay delivery;

• approve substitutions;

• or waive a requirement.

Those changes may be written or, in some cases, shown by conduct.

This can create disputes.

For example, one party may say:

“You agreed I could deliver late.”

The other party may say:

“No, I only agreed to discuss it.”

The practical rule is simple:

If a contract changes, put the change in writing.

What If You Breached Too?

Sometimes both sides accuse each other of breach.

For example:

• one party says payment was not made;

• the other says the work was defective;

• one party says goods were delivered late;

• the other says delivery was delayed because information was missing;

• one party says the contract was terminated improperly;

• the other says the contract had already been breached.

In these cases, the order of events matters.

The court may need to decide:

• who breached first;

• whether the breach was serious;

• whether the other party was excused from performance;

• whether one party accepted the breach;

• whether the contract was terminated properly;

• and what loss was actually caused by each side’s conduct.

The practical point is this:

A breach of contract claim often turns on the timeline.

Minor Breach vs. Serious Breach

Not every breach gives the other party the right to cancel the contract.

Some breaches are minor.

Others go to the heart of the agreement.

A minor breach may justify damages but not termination.

A serious breach may justify ending the contract and suing for losses.

Examples of potentially serious breaches include:

• refusing to perform at all;

• failing to pay a substantial amount;

• missing an essential closing or delivery date;

• delivering something fundamentally different from what was promised;

• failing to complete an essential obligation;

• or conduct showing the party no longer intends to be bound.

The practical rule is simple:

Before terminating a contract, make sure the breach is serious enough to justify that step.

What Is Repudiation?

Repudiation occurs when one party shows they do not intend to perform the contract or will only perform in a way that is substantially inconsistent with the agreement.

Examples may include:

• refusing to complete the deal;

• stating they will not pay;

• insisting on new terms not in the contract;

• abandoning the work;

• refusing to close a transaction;

• or making performance impossible.

If one party repudiates, the other party may have to decide whether to accept the repudiation and treat the contract as ended, or insist on performance.

This decision can have legal consequences.

The practical point is this:

Do not treat a contract as ended unless you are confident the other party’s conduct legally justifies it.

What Remedies Are Available?

The most common remedy for breach of contract is damages.

Damages are money intended to compensate the innocent party for loss caused by the breach.

Depending on the case, remedies may include:

• unpaid amounts;

• cost to complete work;

• cost to repair defective work;

• lost profits;

• loss of bargain;

• wasted expenses;

• replacement costs;

• interest;

• contractual fees or penalties, if enforceable;

• return of a deposit;

• loss caused by delay;

• or other proven financial losses.

In some cases, the court may also consider non-money remedies, such as:

• specific performance;

• injunctions;

• declarations;

• return of property;

• or enforcement of a contractual obligation.

The practical rule is simple:

The remedy should match the breach and the evidence.

Can You Get Specific Performance?

Sometimes.

Specific performance is a court order requiring the other party to do what the contract requires.

It is not automatic.

Courts usually consider whether money damages are enough.

Specific performance may be more realistic where the subject matter is unique or damages are difficult to calculate.

It may arise in some real estate disputes, business purchase disputes or cases involving unique property.

But in many ordinary contract disputes, damages are the main remedy.

The practical point is this:

You can ask for more than money in some cases, but you need a legal basis for that remedy.

Can You Claim Emotional Distress?

Usually, breach of contract claims focus on financial loss.

A contract dispute may be stressful, frustrating and upsetting.

But emotional upset alone is not usually the main measure of damages in an ordinary commercial or payment dispute.

There may be exceptions depending on the nature of the contract and the facts, but most breach of contract cases are about economic loss.

The practical rule is simple:

Focus on provable financial loss.

What If the Contract Has a Limitation of Liability Clause?

Many contracts contain clauses that limit damages.

For example, a contract may say:

• liability is limited to the amount paid;

• consequential damages are excluded;

• lost profits are excluded;

• claims must be made within a certain time;

• remedies are limited to repair or replacement;

• deposits are forfeited;

• or certain damages are not recoverable.

These clauses can matter.

But they are not always simple.

A court may need to consider the wording, the type of breach, the parties’ relationship and whether the clause applies to the loss being claimed.

The practical point is this:

Before suing, check whether the contract limits what you can recover.

What If the Contract Has a Termination Clause?

A termination clause may explain when and how the contract can be ended.

It may require:

• written notice;

• a cure period;

• a specific default;

• delivery of notice to a particular address;

• payment of outstanding amounts;

• return of property;

• confidentiality obligations;

• or other post-termination steps.

If the contract sets out a termination process, follow it carefully.

Ending a contract without following the required process can create risk.

The practical rule is simple:

If the contract has a termination clause, read it before taking action.

How Much Can You Sue For?

The amount depends on the loss caused by the breach.

You may be able to claim:

• the amount owed under the contract;

• the difference between the contract price and replacement cost;

• the cost to fix defective work;

• lost profits that can be proven;

• reasonable expenses caused by the breach;

• or other losses that were reasonably foreseeable and caused by the breach.

You generally need evidence to support the amount.

Helpful documents include:

• invoices;

• receipts;

• estimates;

• expert reports;

• bank records;

• accounting records;

• replacement quotes;

• photographs;

• and business records.

The practical point is this:

A damages claim should be calculated, not guessed.

Do You Have to Mitigate Your Losses?

Usually, yes.

A person claiming damages for breach of contract generally must take reasonable steps to reduce the loss.

This is called mitigation.

Examples may include:

• hiring another contractor to finish the work;

• reselling goods where appropriate;

• finding a replacement supplier;

• trying to rent or sell property;

• limiting delay costs;

• preserving damaged goods;

• accepting reasonable alternatives;

• or avoiding unnecessary expenses.

The injured party does not have to act perfectly.

But they should act reasonably.

The practical rule is simple:

You cannot usually let losses grow unnecessarily and expect the other side to pay for everything.

What If the Contract Has a Deposit?

Deposits can create specific issues.

A contract may say what happens to a deposit if one party breaches.

In some cases, the deposit may be forfeited.

In others, it may be returned.

Sometimes the deposit is credited against damages.

Sometimes the deposit may be the exclusive remedy if the contract clearly says so.

This often arises in real estate disputes, business purchases, equipment purchases and service contracts.

The practical point is this:

The deposit clause can significantly affect the value of the claim.

What If the Other Party Cannot Pay?

Winning a lawsuit is not the same as collecting money.

Before suing, consider whether the defendant has the ability to pay.

Questions include:

• Is the defendant an individual or corporation?

• Is the corporation still operating?

• Are there assets?

• Is there insurance?

• Is there a personal guarantee?

• Are there secured creditors?

• Is bankruptcy or insolvency an issue?

• Can a judgment realistically be enforced?

This does not necessarily mean you should not sue.

But collectability should be part of the strategy.

The practical rule is simple:

A good claim still needs a practical recovery plan.

Which Court Do You Use?

The correct court depends on the amount claimed and the remedy sought.

Many smaller civil claims may be brought in the Alberta Court of Justice Civil Division, subject to its monetary jurisdiction and procedural rules.

Larger or more complex claims may need to be brought in the Court of King’s Bench of Alberta.

The Court of King’s Bench may also be required where the remedy sought is outside the Alberta Court of Justice’s jurisdiction.

The practical point is this:

Choose the court based on the claim amount, remedy and legal issues — not convenience alone.

What Is the Limitation Period?

Limitation periods matter.

For many civil claims in Alberta, the general limitation period is two years from when the claimant knew, or reasonably ought to have known, the facts giving rise to the claim.

Alberta also generally has a 10-year ultimate limitation period.

But limitation periods are fact-specific.

The deadline may depend on:

• when the breach occurred;

• when the loss was discovered;

• when payment was due;

• whether the breach was ongoing;

• whether the contract was terminated;

• whether there were acknowledgments or part payments;

• whether another statute applies;

• and whether an exception applies.

The practical rule is simple:

Do not wait to check limitation periods. A strong contract claim can be lost if filed too late.

What Should You Do Before Suing?

Before suing for breach of contract, gather and organize the evidence.

You should collect:

• the signed contract;

• amendments;

• emails and text messages;

• invoices;

• proof of payment;

• proof of non-payment;

• delivery records;

• photos and videos;

• repair estimates;

• expert reports;

• accounting records;

• demand letters;

• settlement communications;

• notes of calls or meetings;

• and a timeline of events.

A clear timeline should show:

• when the contract was formed;

• what each side promised;

• what changed, if anything;

• when performance was due;

• what breach occurred;

• when the breach was discovered;

• what loss resulted;

• and what steps were taken to reduce the loss.

The practical point is this:

Good contract lawsuits are built from documents and timelines.

Should You Send a Demand Letter First?

Often, yes.

A demand letter may:

• explain the breach;

• identify the contract terms;

• state the amount claimed;

• request payment or performance;

• set a deadline for response;

• invite settlement;

• preserve a record of your position;

• and avoid litigation if the other side responds constructively.

A demand letter should be clear and accurate.

It should not exaggerate the claim or make threats that are not grounded in the contract.

The practical rule is simple:

A good demand letter can frame the dispute before court becomes necessary.

Can the Case Settle?

Yes.

Many contract disputes settle before trial.

Settlement may involve:

• payment of money;

• a payment plan;

• completion of work;

• repair or replacement;

• return of property;

• release of a deposit;

• cancellation of the contract;

• mutual release;

• confidentiality;

• or another practical solution.

Settlement can save time, cost and uncertainty.

But settlement terms should be in writing.

The practical point is this:

If a contract dispute settles, document exactly what each side must do.

Common Mistakes to Avoid

There are several common mistakes people make in breach of contract disputes.

Do not rely only on memory. Preserve documents, messages and proof of payment.

Do not wait too long. Limitation periods can bar the claim.

Do not terminate too quickly. Make sure the breach justifies ending the contract.

Do not ignore your own obligations. Your performance may affect your remedy.

Do not exaggerate damages. Claims should be supported by evidence.

Do not forget mitigation. Take reasonable steps to reduce loss.

Do not assume a verbal agreement is impossible to enforce. It may be enforceable, but harder to prove.

Do not assume winning means collecting. Consider whether the defendant can pay.

What This Means Practically

Three rules are worth remembering.

A breach of contract claim starts with the agreement. The contract terms determine what each side had to do.

Evidence matters. Emails, texts, invoices, payment records, photos and timelines may decide the case.

The remedy depends on the breach and the loss. You may be entitled to damages, performance, return of property or another remedy, but the claim must be proven.

Speak With an Alberta Litigation Lawyer

If someone breached a contract in Alberta, the key question is whether the agreement, breach and loss can be proven.

A proper review should consider:

• whether the other party breached;

• whether you performed your own obligations;

• whether the breach was serious;

• whether the contract was properly terminated;

• what damages can be proven;

• whether mitigation steps were taken;

• whether the claim is within the limitation period;

• whether settlement is realistic; and

• which court is appropriate.
