Quick answer
Home Depot directs Canadian deliveries to homedepot.ca. Address and item restrictions apply: the Canadian site excludes PO boxes, and some remote destinations require Customer Support.
Before ordering
For a bulky item, check the delivery method, building access and charges before ordering. Compare equivalent delivery levels; do not assume installation or upstairs handling is included.
Compare the full cost
Compare the same product and quantity, then add the charges actually shown for the order. Distinguish prepaid charges from any amounts still payable by you. Keep the confirmation and applicable terms.
