The most prevalent brands in Canada are ConvaTec, Coloplast, Hollister, Bestbuy Medical and Wellwise Home Health and Wellness. We encourage you to try new products to find the best possible match. Ostomy companies want you to try their products! All will supply free samples upon request. It is an ideal way to ‘test-drive’ different products without cost. When calling, you should specify the type of ostomy you have, your stoma size, and any particular concerns you may have. Not sure what size your stoma is? Your Ostomy Nurse should have given you a measuring template, or you will find one in your current ostomy supplies. It can take time and some trial and error to find the right products for you.
