I need to renew my Vyvanse capsules, which is a controlled drug, for 90 days because I am going on a trip to Canada. My insurance company allows me to take a 90 day service. Is there a law that prevents 90 day services for controlled drugs?

The prescription reads as follows. 30 vyvanse 30mg once a day in the morning, repeatable 5 times

I have always renewed my medication for 30, 60 or 90 days without any problem. Including controlled drugs. Anyway, 90 days is the maximum allowed by my insurance company. I never refill in advance and have no problem with compliance.But on my last trip to the pharmacy, the pharmacist refused. He said that the doctor must now write "serve up to 90 days at a time" on all prescriptions. This is something my doctor never did before and I regularly refilled my medication for 60 or 90 days. Did a new law, new regulation come into effect in April 2018? Or has it always been against the law to serve more than 30 days if the doctor did not write "serve up to 90 days at a time"? If so, does that mean pharmacists were choosing to do 60 or 90 day services despite the absence of the "serve up to 90 days" indication on the prescription?

So there is no Health Canada law, no OPQ regulation that says you have to serve 60 or 90 capsules of Vyvanse, it's just that the pharmacist on duty decided not to serve me more than 30 according to "his judgment". Judgment that he can exercise on any drug, not just control drugs. Is that right?
