Montreal-based National Bank Direct Brokerage (NBDB), a subsidiary of National Bank of Canada, is introducing commissions-free trading of ETFs listed on U.S. stock exchanges.

The discount brokerage first introduced commissions-free trading on ETFs listed in Canadian stock markets around this time last year. NBDB is now the only Canadian discount brokerage to provide commissions-free trades on all ETFs listed on Canadian and U.S. stock exchanges.

NBDB has expanded the pricing policy to appeal to self-directed investors who will not face restrictions on account size or number of trades if a minimum of 100 units are being traded.

“More than ever, our aim is to innovate to meet the needs of self-directed investors. It’s our priority,” says Laurent Blanchard, president of NBDB, in a statement. “By saving on commissions, our clients will be able to build their portfolios and grow their wealth. This change benefits all types of investors.”
