"If you are planning to travel internationally this summer, do not forget to check the requirements of the country that you're visiting, and remember that many countries have had to make sudden changes as they cope with rising cases or severe outbreaks", she said Monday.
That applies to individuals with right of entry, such as Canadian citizens, permanent residents, and those registered under the Indian Act, as well as foreign nationals eligible to enter under existing rules.
Officials said travellers must electronically submit COVID-19-related information to the ArriveCAN app before arriving, meet the pre- and on-arrival test requirements, be asymptomatic and still have a suitable quarantine plan.
The federal government has laid out its plan to roll back some of its COVID-19 measures, and though it lists some loosening of quarantine requirements for people who've received a full course of a vaccine, it doesn't guarantee anything.
Starting next month, fully-vaccinated travellers won't need to quarantine upon entering Canada.
Those arriving by air are required to quarantine for three nights in a government-authorized hotel in addition to the rest of the testing and quarantine requirements.
There are no changes to the border restrictions for travellers who are not fully vaccinated. In this situation, federal officials said that the parents will be able to leave the house during their children's isolation.
This first step in a "phased" border reopening changes nothing for travellers who have yet to receive a vaccine, or who have just had one shot.
The government also announced Monday that in this first step of reopening, worldwide commercial flights will continue to be funneled through the Montréal-Trudeau global Airport, Toronto Pearson worldwide Airport, Calgary global Airport and Vancouver worldwide Airport.
The travel restrictions have been extended to the world, and even the United States for every non-essential travel until July 21, 2021.
Parliamentary members and travel industry leaders have been pleading with the government to re-open the border, which has had devastating economic effects for both countries.
Despite its cautious stance, Prime Minister Justin Trudeau's government had approved a travel exemption for National Hockey League teams earlier this month for the final round of championship playoffs. The CBC vaccine tracker shows today that 65.4% of Canadians have received at least one dose, and 16.2% are fully vaccinated. The government continues to "strongly advise" that Canadians avoid non-essential travel outside of the country.
"We recognize that people are anxiously awaiting to reopen the border", Blair said. "The results of data collected in the first phase, such as the test results of vaccinated travelers will also help to help us to determine the timing of future border measures".
In talks between the United States and Canada last week, the USA government did not endorse setting a specific threshold to trigger lifting the restrictions, a person briefed on the talks said.
