Ontario’s official mobile application for businesses to scan COVID-19 vaccine certificates.

The Verify Ontario app ended June 24, 2022.

The app is no longer available in the Google Play and Apple app stores. If you still have a downloaded version of the app, it will not scan QR codes and is no longer supported with updates.

Who the app is for

Ontario no longer requires businesses and organizations to check for proof of vaccination effective March 1, 2022.

Verify Ontario is an app for businesses and organizations that provides a quick, easy and secure way to scan COVID-19 proof of vaccination.

Businesses and organizations may voluntarily choose to check for proof of vaccination and may use the Verify Ontario app to scan for proof of vaccination.

The app is not for storing or downloading your proof of vaccination. To download your vaccine certificate with QR code, please visit

Technical requirements

You must use:

The app:

  • requires camera access to work
  • updates automatically when the device is connected to the internet
  • can be used without an internet connection to scan most government-issued QR codes, but you must connect to the internet every week for the latest content and rules
  • takes a few seconds to read QR codes on older devices with older processors or cameras

How it works

The app:

  1. accesses a device's camera with permission to scan vaccine certificates with government-issued QR codes
  2. quickly scans a visitor's QR code, which can be a physical copy they've printed or a digital copy on their mobile device
  3. displays a result page verifying a person's COVID-19 vaccine certificate with QR code
  4. protects privacy by only collecting anonymous data for metrics and does not save or track personal information

Verified screen with a green check mark means that the visitor can enter after showing a piece of ID.
Yellow warning screen may mean that the QR code is invalid, the app timed out, or the QR code is printed in a way that the app can’t read it.
Red “X” screen may mean the visitor is not fully vaccinated, 14 days may have not passed since the visitor was fully vaccinated, or there is missing, invalid or incorrect information in the QR code.

How to scan a vaccine certificate

Follow these steps:

  1. Open the Verify Ontario app on your device.
  2. Ask visitors to show a paper or digital, government-issued 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.
  5. If the proof of vaccination is verified with a green checkmark screen, you can confirm the visitor's ID.

An example of Ontario's proof of vaccination

The app will not verify

  • QR codes created using a non-government website or app
  • QR codes issued by health or government institutions that do not follow the Smart® Health Card QR code standards

The app displays a yellow warning results screen if the QR code:

  • does not meet Smart® Health Card QR code standards
  • Is a valid Smart® Health Card QR code, but is not yet recognized by the app
  • is issued to a child under the age of 12, or who turned 12 within the last 12 weeks (84 days)

Visitors can go to:

Data collection and privacy

For privacy and security:

  • verified vaccine certificate results are displayed for 30 seconds and then deleted
  • only trusted Smart® Health Card QR codes will scan as verified and display a green check mark screen
  • the app does not request the user's location or save any information that links specific locations, visitors or businesses to each other
  • no personal health information is displayed or shared, only the information that is required for QR code verification (result with name and date of birth to confirm an individual's ID)
  • the app only collects anonymous statistical data (analytics) that help us improve the app, including the total number of scans and the number of valid, invalid, or warning results
  • for transparency and security we will share the app's code in GitHub and have adopted a vulnerability disclosure policy
