Canadian and US business leaders also banded together Tuesday, issuing a fresh appeal to the federal government to start putting plans in place.
"We are looking at how we can ease the rules, based on science", for would-be travellers who have had a complete course of a COVID-19 vaccine, Trudeau said in French during a news conference in Ottawa.
Anyone coming to Canada would need to be fully vaccinated before arriving, Trudeau said during an afternoon event, because the country can't risk another wave of COVID-19. "It would help facilitate a safe and gradual return to a more normal life". "That's why we continue to encourage people to get double vaccinated to make sure we can end with this as quickly as possible".
Every month since March 2020, Canada and the USA have extended the border restrictions to curb the spread of COVID-19.
Trudeau has mentioned a 75% vaccination rate as a key threshold when asked about potentially reopening the border.
"There is a lack of urgency on the Canadian side for planning for the inevitable reopening of the border, which has been out of step with US officials and the Biden administration", president and CEO Beth Potter said in a statement. "June 21, the 21st of every month, is the day on which the measures we've had for many, many months between Canada and the United States does gets rolled over or not", he said.
The Prime Minister, however, did not offer any timeline for reopening the border.
The U.S. and Canadian chambers of commerce and other business groups said in a joint statement on Tuesday that the two governments should allow fully vaccinated travelers to cross the border starting June 22.
This weekend, I called for answers and said I would be pursuing all legislative angles to get them.
Federal officials have looked to restrict movement of non-essential travellers for more than a year, even banning at times direct flights from countries like India and the U.K.as variants of COVID-19 have raised concerns.
Although the measures exclude trade, the tourism sector and airlines complain they are suffering financially. One estimate says the measures cost those industries about $20 billion (US$16.5 billion) in revenue past year.
In addition to removing the COVID-19 test and quarantine requirements, the business groups are also asking the Canadian and USA governments to mutually recognize vaccine credentials to support the movement of inoculated citizens and produce a plan the includes clear guidelines for all other travelers.
