"Canadian businesses just have to be prepared for some challenges over the next four years, no matter who wins," said Keller, a vice-president with government relations firm StrategyCorp.

The Liberal caucus turned its attention to the party's plan for the next election on Wednesday, after an unsuccessful attempt by some MPs to oust Prime Minister Justin Trudeau last week.

RCMP Commissioner Mike Duheme is among a slate of top security officials set to meet the House of Commons national security committee, weeks after making explosive allegations against the Indian government.

Two dozen members of caucus signed a letter that gave Trudeau until Monday to respond to their demand for his resignation as party leader but the PM insists he's staying on.

Liberal MPs were tight-lipped about what happened behind the closed doors but those who did speak with reporters as they left the meeting also said the party is united.

Rumours have circulated for weeks about an undisclosed number of Liberal MPs who have signed on to the effort to oust the prime minister in the hopes of improving the party's chances in the next election.

While members of the cabinet have defended Trudeau staying on as leader, a number of Liberal MPs have signed onto a letter that aims to convince him to step aside before the next election.

The federal government is expected to boost the minimum hourly wage that must be paid to temporary foreign workers in the high-wage stream as a way to encourage employers to hire more Canadian staff.
