Legal

Terms of Use

Last updated: May 27, 2026

Welcome to Snow Day Predictor Canada. By visiting snowdaypredictorcanada.com, running the snow day predictor, or reading any of our province, city, or editorial pages, you agree to the terms set out below. These terms are written in plain English wherever possible — if anything is unclear, please email admin@snowdaypredictorcanada.com and we will do our best to explain.

The basics

1.About these terms

These Terms of Use form a legal agreement between you (the visitor) and the Snow Day Predictor Canada editorial team (we, us, our). By using any part of snowdaypredictorcanada.com you confirm that you have read these terms and accept them. If you do not agree with any part of these terms, please do not use the site.

We may update these terms from time to time — for example, when we add a new feature, change a third-party data provider, or respond to feedback from Canadian readers. The “Last updated” date at the top of this page shows when the most recent revision took effect. We will not email you about minor edits, so please check back before relying on any specific clause. Your continued use of the site after a revision counts as acceptance of the updated terms.

The service

2.What Snow Day Predictor Canada provides

Snow Day Predictor Canada is a free, public website that helps Canadian parents, students, teachers, and school bus drivers estimate the chance that schools or buses in their region will be cancelled tomorrow because of winter weather. The site has four main components:

  • A predictor tool that runs in your browser, pulls a live multi-model overnight weather forecast for your postal code or city, and returns two probabilities — a school closure probability and a bus cancellation probability — capped at 95%.
  • Province and city pages with editorial content about school boards, transportation consortia, weather zones, and local closure history.
  • A methodology page that documents our five-factor algorithm, the regional profiles we apply, and every data source we use.
  • A library of practical winter guides covering safe snow driving, snow removal, snow blower maintenance, and similar everyday winter topics.

The predictor is a research and convenience tool. It is not an official source of school closure information. We are not a school board, a student transportation consortium, an Environment and Climate Change Canada channel, or any other government authority. Always rely on your local school board, your district’s transportation consortium, or Environment and Climate Change Canada for the official call.

The fine print that actually matters

3.No warranty and limitation of liability

The predictor, all editorial content, and the website as a whole are provided “AS IS” and “AS AVAILABLE.” We make no warranty — express, implied, or statutory — that any prediction will be correct, that the site will be available without interruption, or that any specific result will be returned for your postal code or city.

Snow day forecasts are probabilistic. A 70% probability means we believe there is roughly a seven-in-ten chance of closure based on the inputs we evaluate — it does not mean schools will close. We cap every prediction at 95% on purpose, because we never want to imply false certainty about a weather-driven decision that is made by a human superintendent at 5:30 in the morning.

Always verify school closures with your local school board, your transportation consortium, or Environment and Climate Change Canada before making a decision that depends on the forecast. That includes whether to send your child to school, whether to drive to work, whether to schedule a medical appointment, and any other choice with real-world consequences.

To the maximum extent permitted by Canadian law, Snow Day Predictor Canada, its editorial team, its contributors, and its data providers are not liable for any direct, indirect, incidental, consequential, special, or punitive damages arising from your use of the site or any decision you make based on a prediction. That includes — without limitation — missed classes, missed work, missed appointments, transportation choices, property damage, personal injury, or any other loss.

Nothing in these terms excludes or limits any liability that cannot be excluded or limited under applicable Canadian consumer-protection legislation. Where such legislation applies, our liability is limited to the minimum permitted by that legislation.

What you can and cannot do

4.Acceptable use

You may use Snow Day Predictor Canada freely for personal, non-commercial reference — checking tomorrow’s forecast for your own family, your students, or your bus route is exactly what the site is for. To keep the service available and accurate for everyone in Canada, you agree that you will not:

  • Scrape, mirror, syndicate, or republish substantial portions of our editorial content, predictor output, regional profiles, or historical event database without our prior written permission.
  • Use any automated process — bots, scrapers, headless browsers — to generate large volumes of predictor queries or overwhelm our backend or our upstream weather data providers.
  • Attempt to interrupt or interfere with the operation of the site, including any denial-of-service, security probe, or similar activity.
  • Reverse engineer, decompile, or otherwise attempt to derive the underlying source of the prediction algorithm beyond what we have publicly documented on our methodology page.
  • Misrepresent a Snow Day Predictor Canada prediction as an official school board or Environment and Climate Change Canada announcement.
  • Use the site for any purpose that is unlawful, fraudulent, or harmful to other Canadian users.

Journalists, educators, and academic researchers who want to quote numbers from a specific prediction, embed a screenshot in a story, or cite our methodology are welcome to do so with appropriate attribution. Send an email to admin@snowdaypredictorcanada.com if you have questions about a specific use case.

Ownership

5.Intellectual property

The Snow Day Predictor Canada name, the logo, the visual design of the site, and the editorial copy on every province, city, methodology, and guide page are our intellectual property and protected under Canadian and international copyright law. You may not copy, reuse, or build on this content beyond what is permitted by the “Acceptable use” section above.

The five-factor prediction algorithm, the per-province closure thresholds, the regional weather profiles, the historical event database, and the city coverage notes are all original editorial and engineering work by the Snow Day Predictor Canada team. They are proprietary to us and were assembled by reading school board policies, transportation consortium notices, and Environment Canada documentation across many winter seasons.

Some inputs to the site are third-party data used under each provider’s respective licence — for example, raw weather forecast fields from Open-Meteo and WeatherAPI, and Canadian Forward Sortation Area geocoding from zippopotam.us. Their data remains the property of their respective owners; we attribute them on our methodology page and in the site footer.

If you submit feedback, a correction, a school board update, or any other suggestion to us — by email, by contact form, or through any other channel — you grant us a worldwide, royalty-free, non-exclusive licence to use that submission to improve the site. We will not publish your name or email address without your permission. You agree not to send us anything you do not have the right to share.

External services

6.Third-party services

Snow Day Predictor Canada relies on a small number of external services to deliver the predictor. The current list includes:

  • Open-Meteo — multi-model weather forecast ensemble, including the Canadian Meteorological Centre’s GEM model.
  • WeatherAPI — additional hourly forecast data used to cross-check the primary ensemble.
  • zippopotam.us — postal code geocoding for every Canadian Forward Sortation Area.
  • Google Analytics and Google AdSense — we may use these services for traffic measurement and display advertising. We disclose what we collect and how it is used in our privacy policy.

Each third-party service has its own terms of service and privacy policy. We do not control their behaviour or guarantee that their data is correct, timely, or available. If a third party suffers an outage, the predictor may temporarily be unavailable or fall back to a single forecast model — we will display a notice on the predictor when this happens.

For the full list of third parties and the data each one receives, see our privacy policy.

How the site is funded

7.Advertising

Pages on Snow Day Predictor Canada may display advertising from Google AdSense or a comparable display advertising network. Where we run advertising it is clearly labelled — either with a “Sponsored,” “Ad,” or “Advertisement” marker, or through the standard AdChoices icon supplied by the network.

Advertising does not influence editorial content. We do not accept sponsored predictions, paid forecasts, or paid coverage of specific school boards, transportation consortia, weather products, winter tires, snow blowers, or anything else. The predictor’s output and our editorial content are produced independently of any advertiser relationship.

If you ever see something on the site that looks like a sponsored prediction or paid editorial coverage, please email admin@snowdaypredictorcanada.com — we want to know about it.

Weather is uncertain

8.Disclaimers specific to weather forecasts

Weather is inherently uncertain. Even the best-tuned numerical models run by Environment and Climate Change Canada, the U.S. National Weather Service, ECMWF, and other agencies disagree with each other about overnight snowfall totals, freezing rain timing, and wind chill minima. Our predictor cross-checks several models and returns a single probability, but the underlying forecast can change as new model runs come in.

Our predictor is a research and convenience tool. It is not a replacement for:

  • Your local school board, district, or service centre — they make the official closure call between 5:30 am and 6:30 am.
  • Your student transportation consortium — they make the official bus cancellation call on the same morning schedule.
  • Environment and Climate Change Canada (ECCC) — the federal authority responsible for winter weather warnings (Blizzard, Winter Storm, Snowfall, Freezing Rain, Extreme Cold, etc.). For severe weather safety information, always consult ECCC.
  • 9-1-1 in any emergency, including a vehicle stuck in a storm, a medical event in cold weather, or a downed power line.

If conditions on the ground differ from what our predictor showed last night, trust the conditions on the ground.

For everyone

9.Accessibility

We aim for Snow Day Predictor Canada to meet WCAG 2.1 Level AA accessibility guidelines across every page — including colour contrast, keyboard navigation, screen-reader semantics, and form labelling on the predictor. Accessibility is not a one-time project and we may not always be perfect, so if you encounter something on the site that does not work with your assistive technology, please tell us.

Report accessibility issues to admin@snowdaypredictorcanada.com. Please include the page URL, the assistive technology and browser you were using, and a short description of what went wrong. We aim to acknowledge accessibility reports within five business days.

Misuse

10.Indemnification

You agree to indemnify, defend, and hold harmless Snow Day Predictor Canada, its editorial team, its contributors, and its data providers from and against any claim, demand, loss, liability, damage, or expense (including reasonable legal fees) arising out of or related to your misuse of the site, your breach of these terms, or your violation of any applicable Canadian law in connection with your use of the site.

In plain English: if you use the site in a way these terms tell you not to, and that causes a problem for us or for someone else, you are responsible for the consequences — not us.

The site evolves

11.Modification and termination

We may update, change, suspend, or discontinue any part of Snow Day Predictor Canada at any time without notice — for example, retiring an old province page, adding a new city, changing a regional threshold to reflect an updated school board policy, or rebuilding the predictor on a new forecast provider.

Outdated content — old province pages, dead links to a school board that has since been merged, references to a deprecated weather model — will normally be redirected to the closest current page or removed entirely. If a URL you previously bookmarked stops working, the most recent equivalent is usually one click away from the navigation or footer.

We may also terminate or restrict access to the site for a specific user or IP address that is in breach of these terms (for example, an automated scraper). We will not refuse service for a personal, non-commercial use of the predictor.

Canadian law

12.Governing law and jurisdiction

These Terms of Use, and any dispute or claim arising out of or in connection with them or their subject matter, are governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable in Ontario, without regard to any conflict-of-laws principles.

You and Snow Day Predictor Canada agree that the courts of the Province of Ontario have exclusive jurisdiction to settle any such dispute or claim, and you submit to the personal jurisdiction of those courts. Nothing in this clause limits any statutory right you may have under the consumer-protection law of the Canadian province or territory where you live.

Cleanup clause

13.Severability

If a court of competent jurisdiction finds that any clause of these terms is unenforceable, illegal, or void, that clause will be removed or limited to the minimum extent necessary, and the remaining terms will continue in full force and effect. The failure of either party to enforce any right under these terms on any occasion does not waive that right on any later occasion.
