A federal economic aid package worth $82 billion was unveiled Wednesday to help Canadian workers and businesses weather the COVID-19 storm, which came as Canada and the U.S. agreed to temporarily close their shared border to non-essential travel.

In an address to the nation, Prime Minister Justin Trudeau said workers who don't qualify for employment insurance can apply to receive the Emergency Support Benefit every two weeks for 14 weeks.

He said applicants can include those who are placed in quarantine or have to self-isolate, those who are ill with the coronavirus infection, and those who must stay home to care for someone with COVID-19.

The program is also for those who must stay home from work to care for children, and those who are without paid sick leave or similar workplace accommodation, the government said online.

The federal government will provide up to $27 billion in direct support to Canadian workers and businesses, plus $55 billion to meet the liquidity needs of businesses and households through tax deferrals to help stabilize the economy.

The response plan includes longer-term income support for Canadians who lose their jobs or face reduced hours as a result of COVID-19.

Shortly after, Alberta Premier Jason Kenney announced his own economic relief package, including $50 million to support those in the province who are self-isolating but have not yet received assistance from the federal government.

There was some hopeful news in the global effort against the pandemic: There were no new cases reported Thursday in the virus epicentre of Wuhan, China and its surrounding Hubei province, according to the country's health ministry.

Earlier Wednesday, U.S. President Donald Trump and Trudeau announced the unprecedented decision to partially close the border. Trudeau said it will affect tourists and shoppers, but goods will continue to move across the border. In response, Air Canada said it will gradually suspend most of its international and U.S. transborder flights. The suspensions will begin now, and be fully in place by March 31.

Canada Post also announced its own service reduction, suspending on-time delivery guarantees for all parcel services indefinitely. Meanwhile, Health Canada announced in a press release that regulation around some disinfectants, hand sanitizers and equipment like masks and gowns would be relaxed due to their "unprecedented demand and urgent need."

Some products with English-only labelling, or that are not currently authorized for sale in Canada but are authorized in "jurisdictions with similar regulatory frameworks," will temporarily be allowed to be sold. Approval for other similar products are being expedited as well, they said.

In the U.S., Trump invoked emergency authority on Wednesday, authorizing the Defense Production Act. The Korean War-era law gives the president authority to steer industrial output, overcoming shortages of face masks, ventilators and other supplies as hospitals brace for an expected onslaught of cases. At the same time, Ford, General Motors, Fiat Chrysler, Honda and Toyota all said they will temporarily close plants in North America.

Later on Wednesday, U.S. Rep. Mario Diaz-Balart became the first member of Congress to test positive for COVID-19. Diaz-Balart self-isolated after votes on Friday then developed symptoms Saturday, though said on Twitter he is now "feeling much better." Hours later, another House member, Rep. Ben McAdams, announced he had also tested positive.

On Wednesday, British Columbia and Saskatchewan joined Ontario in declaring a provincial state of emergency, allowing them to protect their supply chains. Quebec, Alberta, P.E.I., Newfoundland and Labrador have all declared public health emergencies. The Northwest Territories, Yukon and Nunavut also joined them Wednesday, though no cases of COVID-19 have been recorded in the territories yet.

The number of confirmed and presumptive cases in Canada has risen to 727, with nine deaths — seven in B.C, one in Ontario and one in Quebec.

For most people, COVID-19 causes only mild or moderate symptoms, such as fever and cough. However, for older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The vast majority of people recover from the virus in a matter of weeks.

Efforts to slow the spread of the virus are being ramped up as the number of cases worldwide approaches 200,000 in more than 160 countries.

WestJet warning for recent flights

WestJet says some of its passengers may have been exposed to others infected with the coronavirus on 14 recent flights between Feb. 28 and March 12.

The airline said on its website that public health officials are recommending people who sat in certain rows to self-isolate for 14 days after arrival and monitor symptoms, which could include fever, cough and trouble breathing. It says passengers in affected rows are considered close contacts to those infected and could be at risk of exposure.

We will be, by mutual consent, temporarily closing our Northern Border with Canada to non-essential traffic. Trade will not be affected. Details to follow! —@realDonaldTrump

Dr. Theresa Tam, Canada's top public health official, tweeted on Tuesday that about 42,000 people in Canada have been tested for the virus.

"So we're doing OK, we're ramping up quickly, but we just don't have enough tests right now," Canadian respirologist Dr. Samir Gupta told CBC News on Wednesday.

Canada is conducting about one-fifth as many tests per capita as what has been carried out in South Korea, Gupta said, "so we need to get there."

He said the Canadian health-care system is largely testing people who have symptoms of COVID-19, have known exposure to someone with the virus, or have travelled to hotspots. Ideally, testing would be available to anyone with symptoms of a cold, he said.

In the U.S., the government is considering a stimulus plan worth at least $850 billion, which could include sending direct payments to Americans. Trump's proposal would include $250 billion US for small businesses and $50 billion US for airlines.

The Trump administration is also considering a plan to turn back all people who cross the border illegally from Mexico, two administration officials said Tuesday, using powers they say the president has during pandemics like the coronavirus outbreak to mount what would be one of the most aggressive attempts to curtail illegal immigration.

The plan is under consideration and no final decisions have been made, according to the officials, who spoke on the condition of anonymity.

Meanwhile, the head of the World Health Organization (WHO) called on countries to take a comprehensive approach to fighting the pandemic and to isolate, test and trace as many cases as possible.

"To suppress and control the epidemic, countries must isolate, test, treat and trace," said Tedros Adhanom Ghebreyesus. Otherwise, he said, transmission chains can continue at a low level and then resurface once distancing measures are lifted.
