Photographers waited to greet the planeload of immigrants arriving in the Canadian city of Calgary the day Jim Chu Xiaosun and his family first set foot in the country. It was 1962 and a picture taken for a newspaper shows an excited group of 30 people from Hong Kong and China arriving to start new lives. One of them - Chu, who was three years old - would, 45 years later, become the first Chinese police chief of a major Canadian city.
Of those who arrived that day, Chu's father was the only one who could speak English. He had become fluent in the language 20 years earlier, during the second world war, by talking to American Flying Tigers pilots, who had come to help China fight the Japanese.
'He was taught by the Americans in the air force how to repair typewriters and adding machines,' says Chu. After the war, Chu's father built up a successful typewriter company, one of the largest in Shanghai. But times were tough and Chu and his sister were born into a time of famine.
'My mother had left for Hong Kong. My father then applied for permission to go to Hong Kong. He argued his kids needed their mother. He was granted permission and he turned over all of his assets [to the mainland government],' says Chu.
Once in Hong Kong, Chu's father went to the Canadian embassy and asked to immigrate. 'He told the officer he knew about Canada because he was educated by Canadian nuns.'
When the family arrived, Chu's father got a job fixing calculators and typewriters, then he became a taxi driver.
