Parks Canada says a weekend drenching of rain on parts of Jasper National Park is doing a lot to quell fire activity, but the wet weather also comes with a warning.

In a daily update on the local wildfire situation, Parks Canada says parts of the national park received over 30 millimetres of rain on Friday night.

Cooler temperatures were also in the forecast, which the agency says could further decrease fire activity.

Traffic at Canada's two largest railways is slated to resume today as a rail work stoppage comes to an end following a Saturday decision from the federal labour board. 

Canadian National Railway Co. and Canadian Pacific Kansas City shut down railways last Thursday, locking out workers and disrupting freight traffic countrywide and commuter lines in the Toronto, Montreal and Vancouver areas.

The lockouts affected more than 9,000 railway workers amid an ongoing contract dispute between the two companies and the Teamsters union.

One of Canada's most scenic highways has reopened as the wildfire in Jasper National Park continues to be held.

Jane Park, incident commander with Parks Canada, says Highway 93, also known as the Icefields Parkway, is now open to through traffic.

But she warns travellers must head straight through the mountain- and glacier-lined road without stopping.

She says there are no services available on the highway between the town of Jasper and the Icefields Discovery Centre and Saskatchewan River Crossing, a stretch of about 150 kilometres.

The federal government is intervening in a countrywide work stoppage at Canada's two biggest railways, but railworkers are pushing back against Ottawa's move to get them back on the job.

In the culmination of months of increasingly bitter negotiations, Canadian National Railway Co. and Canadian Pacific Kansas City Ltd. locked out 9,300 engineers, conductors and yard workers in the early hours of Thursday.

Here are the latest developments on the rail stoppage (all times are ET):

———

The Teamsters Canada Rail Conference says it has taken down picket lines at Canadian National Railway Co. and its workers will begin returning to work on Friday.

However, the union says the work stoppage at Canadian Pacific Kansas City Ltd. remains ongoing pending an order from the Canada Industrial Relations Board.

Following months of increasingly fraught contract talks, Canada's two biggest railways both locked out workers after failing to reach deals with the union by a Thursday deadline.

Mounties say they are responding to additional bomb threats made across Canada today that they believe are linked to similar threats made the day before. 

RCMP say they responded to the threats alongside local police at synagogues, museums, malls, ports, art galleries and more.

RCMP say they are working closely with domestic and international police to identify who may be involved in the threats, and that they will provide an update on their investigation when it can. 

A coalition of business groups is calling on the federal government to prevent a work stoppage at Canada's two biggest railways.

A phased shutdown of the networks at Canadian National Railway Co. and Canadian Pacific Kansas City Ltd. is already underway as the clock ticks down on contract talks with the Teamsters Canada Rail Conference.

Unless deals are reached, rail service at both companies is poised to stop at 12:01 a.m. ET on Thursday.

Former provincial cabinet minister and pro football player Obby Khan is launching a bid for the leadership of Manitoba's Progressive Conservative party.

Khan says people have been asking him to run for the party helm, and he wants to rebuild the party's connection with Manitobans.

Khan is the first candidate in the race to replace Heather Stefanson, who announced her decision to step down after the party lost last year's election to the NDP.

Monday's supermoon was the first of four this year.

During a supermoon, the full moon inches a little closer than usual to Earth. A supermoon isn't bigger, but it can appear that way in the night sky, although scientists say the difference can be barely perceptible.

September's supermoon will coincide with a partial lunar eclipse. October's will be the year's closest approach, and November's will round out the year.

Global Affairs Canada said Monday it's aware of reports that a Canadian has died after a luxury superyacht sank off Sicily during a violent storm, while Italian authorities said they continued to search for six people who remained unaccounted for.

In a statement Monday afternoon, Global Affairs said consular officials were in contact with local authorities, but said it could provide no further information due to privacy concerns.

"We extend our deepest sympathies to everyone affected by this tragic event," the agency said.
