Step-by-step explanation:
According to the information provided, large organizations in Canada represent slightly less than half of all workers in private firms. Small businesses, on the other hand, account for another 35% of workers in the Canadian economy. It is important to note that this information pertains to workers, not necessarily the number of companies. Therefore, we cannot determine the exact percentage of companies in Canada that are represented by large organizations and small businesses.
