FWI; Within five years Canada cuts the US off from its oil. Refines at home.
As of 2023 Canada produced approximately 5 billion barrels of oil per day. However only refined 1.9 billion across 17 refineries. The remainder was sold abroad with 80% of it being sold directly to the USA markets.
In response to the Canada-US Trade wars, Canada moves to become more industrially independent, beginning with oil. The US markets are completely cut off and Canadian govermnent vows to double oil refining capacity by 2030 and succeeds. Daily refinement of fuel and other crude-oil products reaches 4 billion barrels.
