You should be able to disregard the email. They will call you with instructions for biometrics. This is the quote from the website:
"
Service Canada Centres are gradually resuming biometrics collection services for permanent residence applicants who have received a biometric instruction letter (BIL) and have not given their biometrics within the last 10 years.
Service Canada officers will call you at the telephone number you provided in your application to schedule your biometrics appointment. There is no additional fee to pay, and you don’t need a new BIL."
