Prime Minister Justin Trudeau and United States President Joe Biden talked about the border between their two countries while both were in England for an international leaders' summit.
A Canadian official speaking on the condition of anonymity says the pair talked about the issue on the side of another session with G7 leaders.
The land border between the two countries has been closed to non-essential travel for more than a year as part of efforts to slow the spread of COVID-19.
As more people get vaccinated against the virus, both governments are facing questions as to how long the border will stay closed and whether more people will be allowed to cross this summer.
The official says Biden and Trudeau had a brief conversation where they discussed steps their countries are considering for a cautious reopening.
The summit marks the first time the leaders have been able to meet in person since Biden took office after winning last fall's U.S. presidential election.
The current restrictions against all non-essential travel across the Canada-U.S. border, in place since March 2020, are set to expire June 21.
