Visa information

Apply now for your travel visa or Electronic Travel Authorization (eTA)


Most people need a visa or an Electronic Travel Authorization (eTA) to travel to Canada – not both. Some people may only need their valid passport.

Find out what travel documents you need by visiting the Canadian government visa page.

SPIE recommends that you secure your travel visa before registering for the conference as cancellations after the preregistration cutoff may result in a cancellation fee.
