“2025 was an extraordinary year for Trans Mountain – one that underscored our purpose, our responsibility to Canadians and the critical role we play in connecting our country’s resources to the world,” said Mark Maki, Chief Executive, Trans Mountain. “For more than 72 years, Trans Mountain has safely and reliably moved oil and refined petroleum products to customers, and our sixth sustainability report highlights the progress we’ve made in a rapidly changing energy landscape.”

• Conducted more than 480 safety inspections
• Enhanced marine safety in 2025 and invested in an advanced weather prediction tool with KOTUG Canada to enable more accurate tug deployment decisions, improving vessel transit safety in challenging conditions and helping protect the West Coast marine environment by reducing navigational risk
