Hey fellow Canadians, got a question for ya. We've been a maintenance company exclusively since we began our business...hence the name C&C Lawn MAINTENANCE. But we're slowly inching our way into landscaping and in fact "Maintenance" will soon change to "& Landscape" in our company name. My question is do landscapers in Canada require a PST #? Of course we've already got a GST# but I didn't think I'd ever need a PST# being in the service industry. However, someone mentioned to me that if we're selling product (e.g. plants bought at a nursery for wholesale, then sold to the customer as part of a landscape install at retail) we may need a PST#. Do you guys have/need one?
