(Wines&Vines) - The first exercise of an amendment to Canada’s 84-year-old Importation of Intoxicating Liquors Act is set to play out as consumers respond to a free shipping offer during Canada’s national holiday this weekend. Tinhorn Creek Vineyards in British Columbia’s Okanagan Valley is offering free shipping as well as 10% off the purchase of cases of wine July 1, Canada Day, “to celebrate the recent passage of Bill C-311, which lifts restrictions on inter-provincial purchasing and shipping.”
