開外幣戶口

可以去銀行問下，例如 HSBC : Power Vantage, 恆生：Bank in one
呢類account有個好好既功能，你可以放多種外幣，因為佢有多種外幣戶口！例如你要入CAD，你只需入返落個加幣戶口，就算加幣跌到得$1都唔關你事，因為只要你將來都係拎返加幣出黎就唔會有currency rate既問題！況且放外幣息口會高d同埋bank 會俾個有底押既OD(overdraft)額你！你有幾多外幣，個OD額就會有幾多！

留意：買賣外幣會會有手續費！但入加幣就唔會有手續費！不過如果HSBC你一次過提取多過$500CAD就會有bank charges，我唔記得幾多，大約5%咁上下！

It depends what kind of currency which you want to deposit in the bank, different bank has different rquirements, please go to thete and ask for details.
It will not be a good idea for you to convert HKD to Canadian dollars as the rate they charge you will be much higher than the others.
