Tell Cabinet to say no to Trans Mountain.

The Trans Mountain expansion poses an unacceptable risk to endangered Southern Resident killer whales, to communities that will be affected by the project, and to the climate. We need your voice to stop it.

Southern Resident killer whales, the iconic fish-eating orcas that live off the coast of British Columbia and Washington State, need a quiet, clean ocean to survive.

But if the Trans Mountain pipeline were to be built, it would mean a massive influx of tankers through their critical habitat. The Southern Residents would be threatened by more underwater noise, a greater chance of being hit by a ship, and a higher risk of an oil spill which would devastate their environment.

The project would also lead to a significant increase in greenhouse gas emissions at a time when the science is clear: We must halve global carbon emissions in less than 12 years, or we will see even more deadly heatwaves, sea-level rise, and wildfires that threaten our health, security, and way of life.

And yet, Canada’s national energy regulator has recommended Cabinet approve the project for a second time — even without a credible plan to mitigate its risks.

Take action to stop the Trans Mountain project. Send a letter to Cabinet now.


Cabinet cannot approve this project. It's the law. 

Thanks to an Ecojustice lawsuit, the Federal Court of Appeal already ruled that Cabinet acted illegally when it approved this project the first time around. Help us make sure the government doesn’t make the same mistake again. 

Please, tell Cabinet to shut the door on Trans Mountain for good.
