Once presenting itself as one of the world’s most welcoming countries to refugees and immigrants, Canada is launching a global online ad campaign cautioning asylum-seekers that making a claim is hard.

The C$250,000 ($178,662) in advertisements will run through March in 11 languages, including Spanish, Urdu, Ukrainian, Hindi and Tamil, the immigration department told Reuters. They are part of a broader shift in tone by Prime Minister Justin Trudeau’s unpopular government on immigration and an effort to clamp down on refugee claims.

Migrants have been blamed for high housing prices, although some experts argue this is a simplistic explanation, and polls show a growing number of Canadians think the country admits too many newcomers.
