In 1987, Lee-Chin took the proceeds from his Mackenzie investment to buy a Kitchener-based company called the Advantage Investment Council (a division of AIC Limited) for $200,000. At the time, the company had holdings of around C$800,000. He renamed the company AIC, and developed it to a fund that today controls around C$6 Billion, with hundreds of thousands of Investors. Following the acquisition of AIC Limited, Lee-Chin set up the Berkshire group of companies – comprising an investment planning arm, a securities dealership and an insurance operation. By 2007, Berkshire amassed more than C$12 billion of assets under administration. In 2007, Manulife acquired Berkshire from Portland Holdings in exchange for shares, making Portland one of the largest shareholders of Manulife.
