A canonical URL that redirects sends mixed signals to search engines.

Why this matters

A canonical URL that itself redirects sends mixed signals to Google — link equity may not consolidate as intended.

When the canonical link points to a URL that 301-redirects elsewhere, Google has to choose: follow the canonical chain or treat the redirect as authoritative. Behavior is inconsistent. Set canonical to the FINAL destination URL (post-redirect) so the signal is unambiguous.
