Trans Mountain Expansion (TMX) (2019-2024)
Canada's federal government spent billions buying the Trans Mountain pipeline to expand it from Alberta to the British Columbia coast, facing repeated legal challenges and cost overruns that ballooned from $5.4 billion to over $30 billion.
The expansion was completed in 2024, tripling capacity to 890,000 barrels per day, but with significant cost overruns.
Proved that federal intervention can overcome provincial and environmental opposition, albeit with massive delays and added expense.
Pacific Link seeks to build on TMX's success, using the same federal ownership model and regulatory streamlining to avoid the multi-year delays TMX experienced.
