If you take dividends from your corporation you have decisions to make before the end of 2017. The amount of dividends that you will pay personal tax on for 2017 is based on the amount that you withdrew from your corporation during the 2017 calendar year.
If you have withdrawn all of the dividends that you need, there is nothing else to be done. If you have not taken all of the dividends that you plan to take, you need to do that before the end of the year. Hopefully your salary and dividend decisions have been made.
