66(1)Where a registered dealer has entered into a contract with a client to buy and carry on margin any securities of any issuer either in Canada or elsewhere and where the dealer or a partner, director, officer or employee of the dealer, while the contract is still in effect, sells or causes to be sold securities of the same issuer for any account in which the dealer or a partner or director of the dealer has a direct or indirect interest, if the effect of the sale would, otherwise than unintentionally, be to reduce the amount of securities in the hands of the dealer or under the dealer’s control in the ordinary course of business below the amount of securities that the dealer should be carrying for all clients, the contract with the client is, at the option of the client, voidable and the client may recover from the dealer all money paid with interest or securities deposited in respect of the contract.
