But the federal government will acquiesce to Ontario Premier Doug Ford's demand to temporarily suspend the arrival of global students from overseas, Trudeau said.
"Ford has unabatingly blamed the COVID-19 pandemic's third wave on what he calls" porous borders".
Trudeau said Friday that importation of COVID-19 through the borders is "extremely low" and not a major vector for spread.
Ford didn't stop there, he specified a focus on borders even as he was asked why his government's sick-leave announcement didn't include 10 days of paid sick days, as recommended.
Ford was on a conference call with Prime Minister Trudeau and other premiers last night, where he says he pleaded with Trudeau to do more at the nation's airports, including mandatory pre-departure testing for those flying into Ontario from other provinces.
Border restrictions and airports fall under federal jurisdiction, leaving the premier with little power outside of lobbying the Prime Minister for increased safety measures.
The provincial government is asking Ottawa to implement mandatory three-day hotel stays for all travellers entering Canada by land.
Trudeau said there are already tight controls at land borders, including tests before and after crossing and a mandatory two-week quarantine.
Health Canada now classifies the B.1.617 first identified in India as a variant of interest rather than a variant of concern, because the public health agency doesn't have enough data to definitively say this strain is more transmissible or more unsafe.
Trudeau says he's not considering barring global students from entering Canada at this point, but he's willing to work "more narrowly" with Ontario.
"We need to look outside the box to make sure that we do have enough hotels in and around these border crossings to make sure that they have the ability to accommodate this, Gill said". "But at the same time, we have seen that this third wave is very much around community transmission".
As it stands now, air travellers entering Canada are required to quarantine for at least three days in a specially designated hotel. "Too many people are exploiting these weak measures at our land border to get around the hotel quarantine".
Meanwhile, Ford said he will not relent in his campaign to further restrict global travel "because too much is at stake".
Health officials said there were 295 new COVID-19 cases and one death related to the virus.
Science experts advising Ontario on the pandemic have said it's important to maintain control over entry into the province as new COVID-19 variants emerge.
