Sebastian Cabot (Sebastiano Caboto) and Giovanni da Verrazzano. The first Canadian census enumerating the population was not conducted until 1871. At this time, there were only 1,035 people of Italian origin that lived in Canada. A number of Italians were imported, often as "soldiers of fortune" and "men of letters", to work as navvies in the construction of the Canadian Pacific Railway. In 1904, 3,144 of the 8,576 seasonal Canadian Pacific Railway workforce were Italian men. A substantial influx of Italian immigration to Canada began in the early 20th century when over 60,000 Italians moved to Canada between 1900 and 1913. These were largely peasants from southern Italy and agrarian parts of the north-east (Veneto and Friuli). In 1905, the Royal Commission appointed to Inquire into the Immigration of Italian Labourers to Montreal and alleged Fraudulent Practices of Employment Agencies was launched into deceptive tactics used by padroni, labour brokers that recruited Italian workers for Canadian employers. These numbers were dwarfed in comparison to those of the United States, however, where about four million Italians immigrated between 1880 and 1920. Italian Canadians primarily immigrated to Toronto and Montreal. In Toronto, the Italian population increased from 4,900 in 1911, to 9,000 in 1921, constituting almost two percent of Toronto's population. Italians in Toronto and in Montreal soon established ethnic enclaves, especially Little Italies in Toronto and in Montreal. Smaller communities also arose in Vancouver, Hamilton, Niagara Falls, Guelph, Windsor, Thunder Bay, Sault Ste. Marie, Ottawa and Sherbrooke. Many also settled in mining communities in British Columbia (Trail), Alberta (Crowsnest Pass), Cape Breton Island (Inverness), and Northern Ontario (Sault Ste. Marie and Fort William). This migration was largely halted after World War I, new immigration laws in the 1920s, and the Great Depression limited Italian immigration. Approximately 40,000 Italians came to Canada during the interwar period, predominantly from southern Italy where an economic depression and overpopulation had left many families in poverty. During World War II, Italian Canadians were regarded with suspicion and faced a great deal of discrimination. As part of the War Measures Act, 31,000 Italian Canadians were labelled as "enemy aliens" with alleged fascist connections, and between 1940 and 1943, approximately 600 to 700 of these Italian Canadian men were arrested and sent to internment camps, such as Camp Petawawa—in what was the period of Italian Canadian internment. While many Italian-Canadians had initially supported fascism and Benito Mussolini's regime
