According to Deputy Prime Minister Chrystia Freeland there will be a few exceptions if they are deemed to be essential by the federal government.
Deputy Prime Minister Chrystia Freeland said the government has been "urgently advising" people to self-isolate after returning to Canada from worldwide travel over the past few weeks.
Hajdu told Senate that people who exhibit symptoms of COVID-19 upon their arrival in Canada will be "forbidden from using public transit to travel their places of self-isolation".
This goes into effect at midnight tonight.
Hajdu also said officials will be following up with travellers and will conduct random inspections to make sure they're following the rules. "At the same time, all of us are going to be and feel safer with mandatory quarantines for anyone entering Canada".
"Canadians are great and people have been making real personal sacrifices", she said.
"When you come home it's important to protect your fellow Canadians by self-isolating for 14 days", Njoo said. There is no immediate word on how the government will be enforcing the measure.
Under the Quarantine Act, which received a major overhaul in 2005 following the SARS outbreak of 2003, the federal government can impose significant measures aimed at preventing the spread of a virus.
"I think we all really appreciate that it is so important to have this self-isolation to protect the health and safety of Canadians".
Minister of Health Patty Hajdu says travellers returning home to Canada as of 12 a.m. on Thursday face a mandatory self-isolation for 14 days.
Under the act, those who commit offences can be jailed for up to three years or fined up to $1 million. The Canada-U.S. border has also been closed to all non-essential travel.
Freeland says those essential workers who are permitted to cross the Canada-U.S. border will not be subject to the mandatory quarantine.
