In British Columbia, the role of the incorporator is more important than in other jurisdictions. The incorporator is not only the person who files the corporate paperwork and files it with the government. In addition, the incorporator must receive some of the corporation's initial shares.
There is no limit to the number of shares the incorporator must receive. So it's entirely acceptable for the incorporator to hold a single non-voting common share. The other shareholders can hold a much larger number of shares, making the incorporator's single share a mere formality.
