Is a broker required to provide a client’s personal details about the client as part of the application form?

As observed by Keenan J. in Varcoe v. Sterling, supra, at p. 212: “Brokers are required to comply with the regulations governing the conduct of their client’s affairs. The cardinal rule of the brokerage business is the ‘know your client rule’. A broker who opens an account for a client is required to obtain from the client an ‘account application form’. it contains detailed information about the client, including age, employment, income, net worth, trading experience and trading objectives, as well as personal and family responsibilities. The broker has an obligation to the client, to himself and to the industry to keep up to date on the client’s circumstances and informed of any significant changes in those circumstances.”
