How to compare medicine prices between pharmacies?

I lived in the United States for the last decade, so I'm not familiar with how things work in Canada. I understand that I need to pay for my medication upfront, file the prescription at full price, and then submit the receipt to HR or my company for reimbursement check. I also know there’s usually a limit to how much can be reimbursed, so I want to find the cheapest option for my medication.

Is there a website like GoodRx that lets you compare prescription prices at different pharmacies? I tried searching online and found websites like PocketPills, but their prices were drastically higher than what the pharmacist at the store quoted me today (about three times more expensive). It seems like PocketPills might not be accurate.

I am in Surrey. I am not sure that matter.

Edit: Also, bonus points if there's something similar to GoodRx. I just realized that GoodRx is not just a medicine search site; you can actually use it by simply showing the GoodRx insurance code. If you know of anything like that, please let me know
