Mine was till January 2020, i got it renewed in september 2019 only. Thats how i got my work permit for 2 years on new passport in december. Its better to renew it as the old cancelled passport on which PR application was issued is usually returned with new one in most cases. Also you can get your spouse name added on new passport, which is an extra support documentand also I have my work permit, but the visa in my passport expires in July, do I need to renew it if they are not on time?
