You now get $25 when you open any ING Direct Canada bank account (with an initial deposit of $100 or more), and use 40014077S1 as your Orange Key referral code.
When you open your account, you'll also get your own Orange Key. Give this to your friends and family, and you each get $25 when then open an account!
You can get up to $2000 in referral bonuses (actually, $2025 when you include the $25 you get for opening your own account).
This is a great deal, and something you should consider carefully.
