Dual-class share structures are prevalent in Canada. It is estimated that over 20% of the companies listed on the Toronto Stock exchange use some form of duel-class structure. For example, Magna International issues both Class A subordinate-voting shares and Class B shares. The Class B shares carry 500 votes for every Class A vote. This structure has allowed Frank Stronach to maintain control of Magna with just 3.4% of the company’s equity. Why do you think dual-class structures have emerged in Canada?
