You can contribute up to $5,000 per year. Your unused contribution room can be carried
forward from year to year. If you make a withdrawal, your contribution room will
increase in direct proportion to the amount you take out. For example, if your initial
contribution of $5,000 goes up in value to $6,000 and you withdraw the entire amount,
your contribution room for the following year will be $6,000 plus the annual contribution
amount of $5,000, for a total of $11,000.
