Log in to your Moka application;
Under the Overview section, click on the goal from which you'd like to withdraw funds;
A new window will open, click on the button in the top-right corner "...";
Enter the amount you wish to withdraw from your account.
Withdrawals are always free (not applicable to RRSP withdrawals).
