The only tablets I ever bought were from India and it took 4 weeks to the US with fast shipping (3 weeks in customs.) So I don’t know if that’ll work for you.
I have no experience buying from them but some places I’ve found that sell capsules (I’m sure they make their own from powder) are:
Research Capsules (no info listed on dosage or quantity)
(30mg, which is too high. But you could open the capsules and take half of the powder.)
Since your in Canada, and if you can get a prescription, look into what it cost to get cialis at the pharmacy there. It’s $50 in the US before insurance but I got mine online from https://www.canadadrugs.com/ for about $20. That’s pricey, but Cialis isn’t cheap. You can look into what it cost to get just he minimum you need for your trip. I have no clue what it’s like to walk into a Canadian pharmacy locally and what the prices will be.
Otherwise take your chances with one of the two links above.
You could always get a bottle or two from purchasepeptides and transfer it to smaller plastic bottles and put it in checked luggage if that’s an option. I doubt the glass bottles would break, especially if you wrapped them. I have no clue if it’s legal to bring that stuff across borders in your luggage, though. At least pills you could claim are prescription.
