Soaring Vancouver real estate prices, health care, energy projects, pipelines, grizzly bears and — who else? — President Trump.

These are the issues voters are talking about as British Columbia holds its election for the provincial legislative assembly on Tuesday.

Bordered by the United States on two sides, British Columbia is home to Canada’s fastest-growing economy and has its lowest unemployment rate. But much of that is potentially threatened by Mr. Trump’s recently announced tariffs on lumber, which affect the province’s booming forestry industry. And the campaigning demonstrates how Canada’s trade dispute with the United States is seeping into domestic politics.

The tight race, which analysts say is too close to call, is fueled by political polarization that often falls along urban-rural lines. The divide makes British Columbia perhaps the most American of Canadian provinces, experts say. “It’s blue state-red state all in one,” said Hamish Telford, a political science professor at the University of the Fraser Valley in Abbotsford.
