That doesn't mean that regulators should "just get out of the way." Appropriate regulation can enhance competition. For example, an important goal of the Competition Bureau is to prevent firms from unfairly restricting competition. Canada became a world leader in promoting competition in financial markets when it adopted many of the recommendations of the Porter Commission of the 1960s.
At a time when policy-makers worldwide favoured extensive government controls on economic activity, particularly within the financial system, Porter broke new ground by coming out strongly in favour of enhancing efficiency through the promotion of competition and freer markets. Competition is enhanced by expanding the scope of a given market.
