Mormons also are heavily involved in the sugar beet industry in Alberta, but this is the result of the land in areas where they have settled as farmers being suitable for the industry.
C&H (California & Hawai'i) is cane, but I think Imperial Sugar of Sugarland, Texas (the old 'cane on the Brazos' company, which took the cane sugar produced on Texas prison farms, as well as from other producers) has sugar products from beets as well as cane- dunno for sure, haven't seen either C&H or Imperial here.
