BUSINESS leaders from Toronto and Hong Kong will come together today for an opening ceremony at the Hong Kong Park to mark the start of a week-long investment and trade promotion. ''Metro Toronto Week in Hong Kong'' aims to foster new investment opportunities between businesses in Toronto and Hong Kong by opening the way for high-level talks between business representatives wishing to forge new investment ties. In a series of forums around the territory this week, the Toronto delegates will meet with Hong Kong business representatives to explore the two-way investment opportunities between Canada and the territory. The business meetings will focus on several key industry sectors including electronics, environmental technology and engineering, building materials and architecture. Amid the round of business talks, there will also be a series of cultural and entertainment events to mark the thriving social links that have been established between the people of Hong Kong and Canada. Canadian Consul in Hong Kong Neil Reeder said children from the Canadian International School Choir, wearing the colours of Toronto's famous Blue Jays baseball team, would perform at today's opening ceremony to welcome the Canadian and Hong Kong delegates. The Canadian delegation will be led by the chairman of the Metro Toronto Council, Alan Tonks, and four mayors from Toronto municipalities. Government of Ontario chief representative Andrew Szende said 75 delegates from Toronto companies had travelled to Hong Kong to take part in the business meetings. ''With a 300,000-strong Chinese population, Toronto already has a large platform on which to build its business links with Hong Kong,'' Mr Szende said. ''During the next week, more than 100 meetings will be held to cater for the demand for business talks.'' The agenda for Metro Toronto Week will also include a promotion of Toronto's college and university facilities.
