Got the same text a little while ago and my mom got the same text a few minutes after mine but from a different number (1-647-643-0386) and I don't have a account with CIBC, my mom does have a card with them
Never respond to text messages from numbers you don't know. This is often a scam. Call the number on your card if you think there is a problem. In fact, legitimate texts or emails from banks will include the instructions: Call the number on your card or visit our website.
