Can I be detained in Canada solely based on an Interpol Red Notice without a formal extradition request?

An Interpol Red Notice alone is not a valid basis for arrest in Canada. Canadian law requires either a provisional arrest warrant issued under the Extradition Act — based on an urgent request from the foreign state — or a formal Authority to Proceed from the Minister of Justice. However, CBSA officers may detain individuals briefly at ports of entry to verify immigration status when a Red Notice appears. If you are held beyond initial screening without a warrant, habeas corpus remedies become available immediately, and any detention may be challenged as unlawful.
