Most things that you buy from Amazon can be returned as long as they are unopen/unworn and within 30 days of the delivery date, defective items are an exception to the unopened rule and follow the same return process as anything else. Simply sign in to your account and head to the online returns center and select the item you want to return from your orders. If the return is due to a defect or a mistake Amazon made you’ll be able to print a free return label, and then you just need to drop off your return at a Canada Post store and wait 2-3 weeks for your refund to go through. If you changed your mind about a product you may have to pay for return shipping if it doesn’t qualify for a free return
