Shepp v. The Queen, 99 DTC 510, [1999] 1 CTC 2889 (TCC) -- summary under Shares

Non-voting Class B common shares of a private company that generally were non-voting and not entitled to dividends (although the directors could choose to pay dividend on the Class B common shares in addition to the Class A voting and fully participating common shares) and that had an equal entitlement with the Class A common shares on a liquidation or winding-up were found nonetheless to have an equal fair market value on a per-share basis with the Class A common shares given that at the valuation date, there was an offer from a third-party arm's length purchaser to purchase the company.
