Is Rheem a Canadian company?

No, Rheem is not a Canadian company, it is an American company owned by Japanese parent, with a Canadian subsidiary called Rheem Canada. Rheem Manufacturing Company was founded in 1925 in Emeryville, California, USA, now headquartered in Atlanta, Georgia, USA, and has been owned by Paloma Industries, headquartered in Nagoya, Japan, since 1988, making it Japanese-owned American company. Rheem Canada is the Canadian division of Rheem, with office and distribution in Canada, selling Rheem water heaters, furnaces, and air conditioners in Canada through contractors and retailers like Home Depot Canada, but it is not independently Canadian-owned, it is owned by Rheem US. Canadian water heater companies include Giant, which makes water heaters in Montreal, Quebec, and John Wood, also made in Canada. Rheem is often mistaken as Canadian because it sells widely in Canada and has Canadian certification CSA, but it is American. So Rheem is not Canadian company, it is American company founded in California, headquartered in Atlanta, Georgia, USA, owned by Paloma Japan, with Canadian subsidiary Rheem Canada, American-owned with Japanese parent, not Canadian-owned, though it manufactures some products for Canadian market and has Canadian distribution.
