The Seniors’ Climate Witness event starts on Saturday, just before Parliament’s fall session begins. The rally asks the Liberal government not to use public money for new pipelines.

Sue Adams, 75, from Antigonish, is taking a train to Ottawa. She says her generation "dropped the ball" on protecting the environment and worries about the impact on younger people.

Nina Newington is driving an electric car that holds four other seniors. She says older people feel a responsibility to protect the generations that will follow.

The seniors are protesting Prime Minister Mark Carney’s plan to spend $40 billion of public money on new pipelines and to boost oil and gas exports. They argue that money should go to affordable clean energy.

Before the trip, the Nova Scotia caravan received a festive send‑off in Digby, then boarded a ferry to New Brunswick on Thursday morning.
