Any hours gained in Canada will count towards the experience requirements for revalidation. However, the hour with an instructor must be done with a JAA FI and the licence must be signed by a JAA authorised examiner. Revalidation/renewal requirements under EASA are pretty much the same as under JAR-FCL except that the flight experience must be gained in an EASA aircraft and mandatory refresher training is required to renew an expired type or class rating.
