in Canada in 1918. Alcohol prohibition began in the First World War and lasted until 1921, when the provincial government established control over alcohol sales, a practice still in place today. Canada's first drug law came about following an inquiry conducted by the federal minister of Labour and future prime minister, William Lyon Mackenzie King. King was sent to investigate damages claims resulting from a riot when the Asiatic Exclusion League led a rampage through Chinatown and Japantown. Two of the claimants were opium manufacturers, and after further investigation, King found that white women were reportedly frequenting opium dens as well as Chinese men. A federal law banning the manufacture, sale, and importation of opium for non-medicinal purposes was soon passed based on these revelations. These riots, and the formation of the Asiatic Exclusion League, also act as signs of a growing fear and mistrust towards the Japanese living in Vancouver and throughout BC. These fears were exacerbated by the attack on Pearl Harbor leading to the eventual internment or deportation of all Japanese-Canadians living in the city and the province. After the war, these Japanese-Canadian men and women were not allowed to return to cities like Vancouver causing areas, like the aforementioned Japantown, to cease to be ethnically Japanese areas as the communities never revived. Amalgamation with Point Grey and South Vancouver gave the city its final boundaries not long before it became the third-largest metropolis in the country. As of January 1, 1929, the population of the enlarged Vancouver was 228,193. Geography Located on the Burrard Peninsula, Vancouver lies between Burrard Inlet to the north and the Fraser River to the south. The Strait of Georgia, to the west, is shielded from the Pacific Ocean by Vancouver Island. The city has an area of , including both flat and hilly ground and is in the Pacific Time Zone (UTC−8) and the Pacific Maritime Ecozone. Until the city's naming in 1885, "Vancouver" referred to Vancouver Island and it remains a common misconception that the city is located on the island. The island and the city are both named after Royal Navy Captain George Vancouver (as is the city of Vancouver, Washington, in the United States). Vancouver has one of the largest urban parks in North America, Stanley Park, which covers . The North Shore Mountains dominate the cityscape, and on a clear day, scenic vistas include the snow-capped volcano
