I just went to a place called "Glen Erin Pharmacy" in Mississauga. They sell Tena, Attends, Tranquility, Molicare, and Abena! The first thing you see when you walk in is a huge selection of Abena products. I bought a 14 pack of Abena Abri Form M4 ($23) and there was no fuss or nervousness from the 2 women working there.
I highly recommend checking it out.
