How Long Do You Have to Give Notice to Sue the City of Calgary for a Fall?

28 May 2026 4 min read No comments Slip, Fall & Public Liability Calgary

Under the strict rules of the Alberta Municipal Government Act (MGA), if you slip and fall on snow or ice on City of Calgary property, you must provide formal written notice to the city within exactly 21 days of the accident. Failing to meet this exceptionally tight deadline can permanently bar your right to sue.

When you suffer a painful slip and fall injury, your immediate thoughts are naturally focused on seeking emergency medical care and managing your recovery. Taking legal action is usually the furthest thing from your mind. However, if your accident occurred on public property-such as a city sidewalk, a municipal transit station, or a public recreation centre-the legal clock starts ticking incredibly fast. Suing a municipality in Alberta is drastically different from suing a private business, primarily due to the incredibly harsh deadlines imposed by provincial law.

Many injured residents in Calgary unknowingly lose their legal right to claim compensation simply because they waited a few weeks too long to contact a lawyer. The Alberta Municipal Government Act (MGA) protects local governments by demanding immediate notification of any potential claims involving snow or ice. In this guide, we will plainly outline these critical deadlines and explain exactly how to protect your rights before the narrow window of opportunity slams shut.

Step-by-Step Process in Calgary

If you suspect the City of Calgary is responsible for your slip and fall, you must act with extreme urgency. The process of holding a municipality accountable requires highly specific administrative steps that must be executed flawlessly. Here is how most successful applicants handle claims against the local government.

Step 1: Identify the Exact Property Owner

The very first step is verifying who actually owns the land where you fell. A sidewalk directly in front of a private business might be the legal responsibility of the shop owner, while the crosswalk a few feet away is strictly City property. Use your phone to take detailed photographs of the exact location, including nearby street signs or landmarks, so your lawyer can conduct a rapid property title search.

Step 2: Draft the Formal Written Notice

📝 You cannot simply call the city helpline to complain; the law demands formal written notice. This written document must clearly state your full legal name, the exact date and time of the incident, the specific location, and a brief description of the injuries you sustained. Given the high stakes involved, it is highly recommended to have an experienced Calgary law firm draft this complex notice to ensure it complies completely with the strict MGA requirements.

Step 3: Serve the Notice to the City Clerk

The written notice must be properly delivered to the correct municipal authority. In Calgary, this typically means formally serving the document to the City Clerk’s office or the designated municipal risk management department. Sending a casual email to a random city official will generally not satisfy the rigorous legal standard required by the Alberta courts.

How Much Does it Cost in Calgary?

Sending the initial mandatory notice to the City of Calgary does not carry a government fee. However, if your claim proceeds to formal litigation, there are standard costs involved. Here is a brief look at the deadlines and typical legal costs:

Requirement / ActionLegal Deadline or Cost (CAD)
Notice Period for Snow or Ice FallsStrictly 21 Days
Notice Period for Other Hazards (e.g., Potholes)Strictly 30 Days
Statute of Limitations (To File the Lawsuit)2 Years from the exact date of injury
Court Filing Fee (Court of King’s Bench)Currently $250 CAD

Because the deadlines are so rapid, most personal injury lawyers will expedite your initial consultation and draft the notice without charging you an upfront hourly rate, operating instead on a standard contingency fee agreement.

How Long Does the Process Take?

While the initial notice must be filed within a mere 21 days, the actual legal lawsuit process is quite lengthy. Once the city is formally notified and your injuries reach maximum medical improvement, your lawyer has up to two years to file the final Statement of Claim. From that point, negotiating with the city’s robust legal department or proceeding to a trial at the Court of King’s Bench can routinely take anywhere from two to four years.

Frequently Asked Questions (FAQ)

What happens if I missed the 21-day notice deadline?

Missing the 21-day deadline is generally fatal to your claim. The Court of King’s Bench will typically dismiss your lawsuit entirely. There are exceptionally rare legal exceptions if you had a “reasonable excuse” (such as being in a prolonged medical coma) and the city was not prejudiced by the delay, but you should never rely on this highly risky loophole.

Does the 21-day rule apply if I fell on a private store’s sidewalk?

No, the strict 21-day or 30-day notice rules under the Municipal Government Act apply strictly to municipal property. If you slip and fall on private commercial property or a residential driveway in Alberta, the standard legal limitation period of two years generally applies.

What if I tripped on a cracked city sidewalk with no snow or ice?

If your fall was caused by municipal disrepair-such as a dangerous pothole, a severely uneven sidewalk, or a broken staircase-and did not involve snow or ice, you generally have 30 days to provide written notice to the City of Calgary under the MGA.

Are the rules the same if I fall on a Calgary Transit vehicle?

Injuries sustained while utilizing Calgary Transit can involve a highly complex mix of municipal liability and standard motor vehicle accident laws. While the 21-day snow/ice rule may not strictly apply to slipping inside a moving bus, you should still immediately notify the city and consult a lawyer to protect your rights.
