Experts call on leaders for unified vision at North American Leaders' Summit

But that's not the way North American diplomats, trade experts and business leaders see it — and they hope the continent's leaders have a similar vision as they gather this week in Mexico City.

Prime Minister Justin Trudeau kicked off three days of North American Leaders' Summit events Monday with a gathering of diplomats, government officials and private-sector emissaries from across the continent.
