TIH: June 23, 1887- The Rocky Mountains Park Act becomes law in Canada creating the nation's first national park, Banff · 0
- With conflicting claims over discovery of hot springs in Banff, Prime Minister John A. Macdonald decided to set aside a small reserve of 26 square kilometres (10 sq mi) around the hot springs at Cave and Basin as a public park known as the Banff Hot Springs Reserve in 1885. Under the Rocky Mountains Park Act, enacted on 23 June 1887, the park was expanded to 674 km2 (260 sq mi) and named Rocky Mountains Park. This was Canada's first national park, and the third established in North America, after Yellowstone and Mackinac National Parks. The Canadian Pacific Railway built the Banff Springs Hotel and Lake Louise Chalet to attract tourists and increase the number of rail passengers.
