  The dominance of the economy by big business was accompanied by an often militant labour movement. The first major sympathy strike was in 1903 when railway employees struck against the CPR for union recognition. Labour leader Frank Rogers was killed by CPR police while picketing at the docks, becoming the movement's first martyr in British Columbia.: 39–41 The rise of industrial tensions throughout the province led to Canada's first general strike in 1918, at the Cumberland coal mines on Vancouver Island.: 71–74 Following a lull in the 1920s, the strike wave peaked in 1935 when unemployed men flooded the city to protest conditions in the relief camps run by the military in remote areas throughout the province. After two tense months of daily and disruptive protesting, the relief camp strikers decided to take their grievances to the federal government and embarked on the On-to-Ottawa Trek, but their protest was put down by force. The workers were arrested near Mission and interned in work camps for the duration of the Depression.
  
  Other social movements, such as the first-wave feminist, moral reform, and temperance movements, were also instrumental in Vancouver's development. Mary Ellen Smith, a Vancouver suffragist and prohibitionist, became the first woman elected to a provincial legislature in Canada in 1918.: 172 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.: 187–188 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.
