Thats what i meant to say . If he renews the Canadian booklet now it will be valid for 5 years and hence the new Indian RTR P will also be valid till the validity of the new RTR P
If the RTR license is on the verge of expiring then its best to get it renewed immediately by renewing the Canadian booklet
Instead of just clearing part 1 and getting 20 years its best to give both part 1 and part 2 and obtain RTR A with lifetime validity and than worry about license renewal 20 years from now
