Winter tourism in Banff began in February 1917, with the first Banff Winter Carnival. It was marketed to a regional middle class audience, and became the centerpiece of local boosters aiming to attract visitors, which were a low priority for the Canadian Pacific Railway (CPR). The carnival featured a large ice palace, which in 1917 was built by World War I internees. Carnival events included cross-country skiing, ski jumping, curling, snowshoe, and skijoring. In the 1930s, the first downhill ski resort, Sunshine Village, was developed by the Brewsters. Mount Norquay ski area was also developed during the 1930s, with the first chair lift installed there in 1948.
