If you are the sole director of a firm or own more than 50% of the company, the CSA can take dividends into account.
However, if you are part of a board and own 50% or less of the company, who are jointly responsible for making dividend awards, the CSA cannot take it into account as you are not in control of the money. The other directors can waive their right to take a dividend and let you take your portion but obviously this needs to be documented in the minutes book. This is covered in the Act and on the CSA website, and even if you ask the call handlers they tell you the same.
Before you think about appointing your new partner a director, the other director cannot be "under your influence" i.e. a partner or offspring living at the same address. Friends who are professionals often are helpful
In short, make sure you own 50% or less, you have two or more directors and that your statutory members list reflects the correct allocation of shares and that companies house have all the correct particulars for the directors and annual returns.
On the plus side, and this sounds vindictive, it does stop those ex's who think that all your hard work should be spent on their holidays/extensions and new partners.
Guess who has gone through it! :)
