No, it is mined from a quarry in the US (far south). There is natural calcium carbonate rock available in Canada but due to its geological age its way too dense to be used as a reef suitable rock. The Reefer Rock is from an ancient coral reef estimated to be around 100,000 years old. Just for reference whats in Canada is millions of years old and therefore more compressed, more dense.
