It is important to consider the Competition Act as a whole. It includes measures for intervening in situations where there is insufficient competition. It regulates the practices and behaviours of actors in the economy. In places where there is only one service station, or where there is a true monopoly, as you said, it is important to increase competition in the market.
The Competition Act cannot restore competition, but it makes it possible to combat the behaviours and practices that throw up barriers to competition, such as abuse of dominance, the use of practices intended to exercise control, attacking competitors, or any other behaviour that has a negative effect on the market. It is important to understand that.
That Act contains a set of measures for intervening in those situations, but that is not the only thing that promotes competition in the market.
