Plans to introduce formal English-language tests for immigrants to Canada are under review. The changes were supposed to come into effect in February. However, changes at the Canadian Immigration Ministry have resulted in a review of the policy, stalling its implementation indefinitely. 'Some people say it will start at the end of the year,' said Kent Lim, president of the Canada-based firm Shellton Immigration Services. 'Some say next year. All I know for certain is that it's under review at the moment.' Proposed changes to the policy for migrants applying under the independent category will place greater emphasis on English-language ability. 'When they implement the new policy they are going to have some kind of English test,' Mr Lim said. 'Until now, language assessment was only based on one-on-one communication with an immigration officer.' The changes to Canada's immigration policy will also place older would-be migrants at a disadvantage. Previously, the ideal independent-immigration candidate fell anywhere between the ages of 21 and 44. Now the Canadian Government is targeting educated migrants from 25 to 35 years. Canada is the front-runner in the international contest to lure wealthy Hong Kong migrants. At an emigration seminar in Wan Chai's China Resources Building, almost all the information booths were festooned with the red maple leaves of Canada's flag. 'Eight out of 10 people here want to go to Canada,' Mr Lim said. Hong Kong ranks as Canada's largest source of immigrants - a position it has held since 1987. Between 30,000 and 35,000 Hong Kong people move to Canada each year. The Canadian Government has said it plans to accept between 195,000 and 220,000 immigrants and refugees this year.
