OTTAWA, March 13 (Reuters) - Canada on Friday moved to suspend the House of Commons, delay the presentation of a new budget, and advised against non-essential foreign travel in an effort to slow the spread of the new coronavirus, senior officials said on Friday.
"We seem to be approaching a different phase right now" with the spread of the virus, said Prime Minister Justin Trudeau, who is in self-isolation after his wife tested positive for coronavirus.
Canada reported 157 cases of the virus, up from 138 on Thursday, with one death. Seven of Canada's 10 provinces have recorded infections of the respiratory illness.
Canada's chief medical officer urged Canadians to cancel all non-essential travel abroad, and said travelers should consider self-isolation upon return to the country beyond the mandatory measures already in place for certain regions.
International flights coming into Canada will be restricted to a few specific airports, Transport Minister Marc Garneau said.
"This is a serious public health threat, as well as a crisis, that has to be taken seriously," Health Minister Patty Hajdu told reporters.
Before shutting down until at least April 20, parliament ratified the new North American trade agreement, Deputy Prime Minister Chrystia Freeland said. Mexico and the United States have already approved the treaty.
The new budget, which was supposed to be presented on March 30, will be delayed. No new date had yet been set.
However, Finance Minister Bill Morneau will make a "significant" announcement today, the Canadian Broadcasting Corp (CBC) said.
Trudeau was due to address Canadians from outside his home shortly.
Trudeau's government is mulling a multibillion-dollar package for industries most hit by the outbreak, including airlines, a source directly familiar with the matter told Reuters. It would allow provinces to take action to support families, workers and employers, the source said.
Quebec's Premier Francois Legault canceled schools across the province for two weeks starting on Monday. Ontario, the most populous province, suspended schools until April 5 on Thursday.
Trudeau announced on Thursday that he would be in isolation for as much as two weeks after his wife, Sophie, became infected with the virus.
Trudeau will be working by teleconference and was to lead a meeting later on Friday to coordinate the response to the outbreak, he said.
