AFAIK Canada can do it quickly because most liquor stores are government owned and run (LCBO in Ontario for example), whereas in Mexico it’s individual retailers. And many of the retailers in Mexico are American chains: Wal*Mart, Costco, etc. If Soriana and Chedraui wanted they could stop selling American booze, but they’re for-profit companies that are probably thinking they’ll just let their customers choose if they want to boycott.
