There's new political muscle in the United States pushing for a return to more regular travel between Canada and the United States after more than a year of pandemic-related disruptions.
The top member of the U.S. Senate, Chuck Schumer, has written a letter to members of the Biden administration making several demands regarding the border.
He's asked Secretary of State Antony Blinken and Homeland Security Secretary Alejandro Mayorkas for four things.
One is a detailed Canada-U.S. plan — released as soon as possible — explaining what rules and health-related benchmarks will guide the return to non-essential travel. He said this should add clarity and transparency to a process that's confused and frustrated people.
And in the interim period, he immediately wants to see Canada and the U.S. allow more people to travel. Schumer wants the definition of essential travellers expanded to include vaccinated people who have property, educational, medical or business reasons for crossing the border.
He also wants clarity for boaters and, finally, he wants a safety plan for border agents including access to testing, vaccines and protective equipment.
Why it matters to Canadians and cross-border travellers
Other lawmakers from Schumer's border state of New York have been making similar calls with little sign of progress. Neither national government has made it a priority to articulate a reopening plan for the border.
But Schumer's entry into the debate is a sign of increased pressure on the national governments to at least begin articulating their longer-term intentions.
"Having endured one of the deadliest chapters in New York's history, the residents along the border are ready to turn the page and re-establish the familiar links to their loved ones, their property and their prosperity," Schumer's letter said.
"It is now incumbent on the federal government to do their part and aid their desperate desire to fully rebuild and recover. This recovery cannot be done, and I will not rest, until bilateral collaboration to safely reopen the United States and Canadian land border is an utmost priority and a plan for a full reopening is publicly released."
One reason for Schumer's optimism about reopening is the progress the U.S. has made on residents receiving COVID-19 vaccines. Nearly 50 per cent of adults in New York state are fully vaccinated, and indoor dining is expanding this week to near-full capacity in New York City.
The United States remains far ahead of Canada in its share of fully vaccinated residents. However, with vaccine hesitancy becoming an issue in many states, the pace is slowing down, and Canada is steadily catching up in the rate of residents having received a first dose.
