Which Ozempic patents matter in Canada?

When do Ozempic (semaglutide) patents expire in Canada?

Are there generic or biosimilar Ozempic equivalents able to enter Canada before patent expiry?
Whether a generic or biosimilar can enter depends on which exclusivity/patent rights are still in force and whether manufacturers can rely on regulatory pathways that are compatible with those protections. In practice, companies often face patent “barriers” even if their drug can be approved—market entry can still be blocked until the relevant Canadian patents (or related protections) expire or are resolved.
