  <Accordion title="How long does BMO card activation take?">
    BMO card activation is usually instant. When you activate at [**https://www.bmo.com/activate**](https://www.bmo.com/activate), by phone, or through the BMO mobile app, your card should become active within a few minutes. In rare cases, it may take up to one hour for the activation to fully process across BMO's payment network.
