Greyhound Canada has serviced notice it plans to halt operations in Manitoba and northwestern Ontario.
It's given 30 days notice in Manitoba and 90 days notice to Ontario.
The bus company says it's also reviewing operations in Alberta,Saskatchewan, B-C, Yukon and the Northwest Territories.
Greyhound says it's in dire financial shape because of government regulations that force it to serve remote communities.
But it says that over the next 30 and 90 days, it will continue to work with the federal and provincial governments to try to find a solution to the emergency.
