The head of auto-parts giant Magna International Inc. has joined a chorus of Canadian executives warning on the business repercussions of recent protests against the Coastal GasLink pipeline.

“This is a good case of insanity,” Don Walker, chief executive officer of Magna, said in an interview with BNN Bloomberg’s Amanda Lang on Thursday.

“The more we allow things like this to happen to Canada, the less competitive we are, the less we look like we’re competitive to the rest of the world, the less people will come here,” he said.

His comments come one day after Cenovus Energy Inc. CEO Alex Pourbaix warned the rail blockades in protest of the proposed pipeline will have a “massive impact” on the Canadian economy.

On Monday, the chief executive of Canadian National Railway Co., JJ Ruest, cautioned that the blockades are disrupting the country’s supply chains and that if they are not removed, the company will have to “imminently” shut down significant parts of its network.

Walker said he believes people should be able to protest, but not at the expense of the livelihoods of other people.

“You shouldn’t be, in my opinion, affecting other people’s lives and business and the competitiveness of our country, because that’s going to have long-term damage.”
