Refining Margins: The difference between the cost of crude oil and the selling price of refined products like gasoline and diesel significantly affects MPC.TO's earnings. Wider margins mean higher profits and a potentially higher stock price.

Geopolitical Events: Global events like political instability, conflicts, or trade disputes can impact crude oil prices and energy markets, thereby affecting MPC.TO's stock price.

Company Performance: MPC.TO's operational efficiency, refining capacity, and ability to manage costs impact its profitability and stock price. Strong operational performance generally leads to a higher stock value.
