Price differences among fed cattle prices in Canada and the United States (referred to here as fed cattle basis) are important for Canadian cattle feeders, but changing government regulations in Canada and the United States have made basis more variable. This article uses transaction data from Canadian feedlots to quantify fed cattle price differentials in light of new policy initiatives. Using transaction prices, we find that differing slaughter regulations, labeling laws, and policies affecting access to U.S. markets for Canadian cattle affect fed cattle basis.
