Internationally Educated Professionals, called they immigrants having non-Canadian degrees, can get bridging programs or similar ones and have to pass qualification and/or provincial exam to continue their profession in Canada.
Don't be surprised. Be prepared for.
No worry. After landing, you will get support to be integrated. How it is quick depending on your capability to adapt the new environment.
