As  eeq20 says, you should check your tax bracket before you contribute to your RRSP. Maximizing does not necessary give you the best return on the long run as you'll need to take it out later in life.  If you are a person that likes to flip stocks, then maximizing it will give you a good place to play the stock market without paying taxes on your gains.

Borrowing to buy RRSP is a gamble on how the stock market will do for the year. If you are lucky, then the stock market goes up enough (at least 6-7%) then you make some money; if not you'll lose money.
