Here's a nice offer from ING Direct. When you open a regular savings account, RSP or TFSA with $100 or more, you'll get a $50 bonus! The offer is open to new clients only, and there's a limit of one bonus per client/account.
It's pretty simple to take part -- just fill out the online form and then mail a cheque of $100 or more to ING. That cheque will be used to link your chequing account to your new ING account for making future transactions. Currently, ING is offering 1.35% interest for savings accounts and RSPs and 1.40% on TFSAs.
