I believe that is contingent on how much you make when you decide to sell, and how much room you have left in your tfsa.  Myself I do not plan on selling for years,so $5500 in contribution room will be added per year to my tfsa that will be tax free. I believe in my heart that I will be paying tax even after I am capped out, but I am alright with that, just means the company is doing well, and we are all making healthy profits.  Long for years to come!
