One of Canada's most vocal investors says he "pissed" as ever about British Columbia's threat to block the flow of bitumen through the province.   

"I'm as pissed as I've ever been in terms of how we're letting regionalism to take over from nationalism," W. Brett Wilson, chairman of Canoe Financial and Prairie Merchant, told BNN in an interview Wednesday.

He said national interests are being "subserved" by a few mayors in British Columbia.

“I don’t know where B.C. thinks the bills are paid, but it’s not Nelson's cannabis grow-ops,” Wilson said, referring to the western city in British Columbia.   

Wilson’s comments come after B.C. earlier this week announced five proposals intended to limit risks tied to oil sands spills. Most notably, the province said it’s considering restricting any increase in shipments of diluted bitumen off its coast.

Wilson also took to Twitter Wednesday to call out B.C.’s proposed measures, which could put the future of Kinder Morgan's Trans Mountain pipeline expansion project at risk.

“What is B.C. smoking? This NIMBYism is misguided - destructive to Canada - and needs to be dealt with,” he wrote. “I suggest slingshots at daybreak .”

 

On BNN, Wilson expressed his support for Alberta Premier Rachel Notley, who said Tuesday her B.C. neighbours are "grasping at straws" and don't "have the right to rewrite our Constitution and assume powers for itself that it does not have."

“For the first time in many years, I’m about to use a hashtag called ‘go Rachel, go,’” Wilson said.  

He argued it's in the country’s "core interest" to focus on building its resource economy and to not let regional interests preside.

"It's really about our national interests and the federal government has failed miserably by taking a side car show about Bombardier and running hard with that, while ignoring the core interests of our nation in terms and building our resource economy,” Wilson said.

"We don't need to kill each other,” Wilson said, referring back to his tweet. “But we have to have a conversation and I want to get their attention."
