As part of Ontario's ongoing fight against COVID-19, and in support of vital public health measures, the province is pleased to introduce Verify Ontario, Ontario's official, free app for verifying COVID-19 vaccine certificates.


Verify Ontario is designed for businesses and organizations of all shapes and sizes. The app reduces the burden on business and makes it quicker and easier to confirm that visitors are fully vaccinated, at the door.


Organizations can download this secure, privacy-protective, made-in-Ontario app from the Apple App and Google Play Stores, starting October 15, 2021. Verify Ontario works with both Apple (iOS11 or newer on iPhone, iPad and iPod Touch) and Android devices (Android 6 or newer).


The app can be used without an internet connection to scan QR codes, but you must connect to the internet every week or so for the latest content and rules.

How does it work?

The app:

  • Accesses a device’s camera with permission to scan vaccine certificates with government-issued QR codes

  • Scans and reads the QR code that is printed on either a piece of paper or displayed on a phone screen

  • Displays a results screen, once it checks against proof of vaccination requirements

  • Does not track or save personal information or visitor location

  • Only collects data for metrics that are not connected to users (for example, number of scans)

How to scan a proof of vaccination?

  1. Open the Verify Ontario app on your device.

  2. Ask visitors to show a paper or digital, government-issued enhanced vaccine certificate with a QR code.

  3. Scan the QR code with the device's camera.

  4. Follow the instructions displayed on the result screen. You will see one of three possible results:

    • a ✅ for “yes” (good to go)

    • a ❌ for “no” (does not meet proof of vaccination requirements)

    • a yellow warning triangle to signal an issue with the certificate (for example, it is not an accepted or it is an invalid QR code)

  5. If the proof of vaccination is verified with a green checkmark, confirm the visitor's ID.

Learn more about what the results mean. Read more about the limited exceptions allowed.

Scans official QR codes

Only official QR codes on vaccine certificates that meet the SMART Health Card standard for privacy and security can be read as valid proof of vaccination. This includes compatible QR codes from other provinces that follow this same standard, including Quebec and British Columbia. QR codes from third-party services are not scannable
