Why am I unable to add Canadian Stock trading permissions to my account?

You may be unable to downgrade your IBKR Margin account to a Cash account due to trades which are not settled yet. To view the settlement dates for your trades, you can access the Trade Confirmation report through the Interactive Brokers (IBKR) Client Portal. This report provides detailed information about your transactions, including settlement dates. …

Due to regulatory restrictions you are limited to trading only bonds that the account has added the relevant "Trading Permissions" If regulations do not allow your account to trade a contract then the trading permission for that product will not be available on your Client Portal Trading Permissions page…

IBKR does not charge a fee when you request and add trading permissions to your account. The requirement for trading permissions is that you meet the qualifications.
