Canadian Prime Minister Justin Trudeau is reassuring refugees they will still be welcome in Canada despite a U.S. ban on Muslim travellers and refugees.

In a series of tweets Saturday, Trudeau said Canada will continue to welcome refugees and immigrants.

“To those fleeing persecution, terror & war, Canadians will welcome you, regardless of your faith. Diversity is our strength,” he said on Twitter. The tweet was followed by a photo of the prime minister greeting the first planeload of government sponsored Syrian refugees at the Toronto International Airport in December 2015.

U.S. President Donald Trump signed an executive order Friday evening suspending the country’s refugee resettlement program and banning Muslim travellers from several countries. The ban affects citizens of Iran, Iraq, Sudan, Somalia, Syria, Yemen and Libya, including those holding U.S. green cards for 90 days. The U.S. State Department told the The Wall Street Journal Saturday the travel ban includes dual citizens.

CBC News reported Saturday several dual Iranian-Canadain citizens traveling to the United States from Canada had been denied entry.

The issue earned attention from Conservative leadership candidate and former Transport Minister Lisa Raitt, who tweeted she and her officials had contacted Global Affairs for more details.

Friday’s executive order suspends the resettlement of Syrian refugees indefinitely and applies a temporary ban on all other refugee resettlement for 120 days.

Trudeau did not say Saturday whether Canada will accept more refugees from Syria and around the world in light of the American ban. When contacted, the Prime Ministers Office referred iPolitics to Trudeau’s tweet.

Transport Minister Marc Garneau’s office said in a statement late Saturday they were in contact with their counterparts in the United States about the ban.

“We are in contact with the U.S. Department of Homeland Security, the U.S. Department of Transportation, and other partners to get more information on the impacts. We will be providing further information to Canadians as available,” the email reads.

iPolitics has also reached out to Foreign Affairs Minister Chrystia Freeland and Global Affairs about the U.S. Administration’s new refugee and travel policy.

As of 4 p.m. EST, Global Affairs has not issued a travel advisory for Canadians travelling to the United States.

Canadian airline WestJet has said it will waive its cancellation policy for traveller with passports from the seven countries banned under the new American policy.
