Jane Fonda, Rachel McAdams Support Vancouver Greenpeace Rally (PHOTOS)

Fonda has said she's willing to be arrested trying to protect the B.C. coast from pipelines and oil tankers.

A rally in Vancouver organized by Greenpeace to protest pipelines and oil tankers got some star power from actresses Jane Fonda and Rachel McAdams.

Roughly 5,500 people attended the Toast the Coast event at Jericho beach on Saturday. The gathering celebrated the beauty of B.C.'s oceans, and opposed Arctic oil drilling, coastal pipelines, and the use of oil tankers.

Fonda, who said she's willing to be arrested defending the B.C. coast, galvanized the crowd with her speech.

"Thirty years from now, I want my grandchildren to be able to look back and say, 'Grandma was on the right side of history,'" Fonda later wrote in a blog post.

McAdams, who is from Toronto, is also a longtime advocate of protecting the environment.
