Your Canadian Red Cross training certifications are valid for 3 years from the original in-person training course date. Within the 3 years of certification, taking a recertification course will extend your certificate for an addition three years. For example: Nas took his Standard First Aid & CPR / AED Level C training course May 17th, 2020. This certificate expires May 17th, 2023. He takes a recertification course on May 16th 2023, saving money and time in addition to the new expiry date of May 16th 2026.
