Interim Conservative leader Rona Ambrose says that she 鈥渄oesn鈥檛 support the idea鈥 behind a proposal from leadership candidate Kellie Leitch to screen immigrants for 鈥渁nti-Canadian values.鈥

Ambrose told CTV鈥檚 Question Period that she 鈥減ersonally鈥 doesn鈥檛 support such screening. 鈥淚 don鈥檛 even know what that would look like,鈥 she said.

Ambrose added that 鈥渁s far as our party is concerned, we value immigration.鈥

鈥淲e just had our convention, the largest convention in the history of our party, 3,000 Tories got together and no one talked about this,鈥 she said.

Chong: 鈥榙og-whistle politics鈥

Conservative leadership candidate Michael Chong, whose parents are immigrants from Hong Kong and the Netherlands, wrote Friday on Facebook that Leitch鈥檚 proposal has been called 鈥渢he worst of dog-whistle politics.鈥

鈥淚n order to win in 2019 we need to build a modern and inclusive Conservative Party that focuses squarely on pocket book issues that matter to Canadians, and not on issues that pit one Canadian against another,鈥 he wrote.

Mulroney: 鈥楰ind of unacceptable鈥

Former Progressive Conservative prime minister Brian Mulroney was asked about Leitch鈥檚 proposal on Question Period and replied that he believes immigrants bring 鈥渄ynamism 鈥 expertise 鈥 devotion and loyalty to Canada.鈥

鈥淚 think anything that diminishes that concept is kind of unacceptable,鈥 he said.

Frum: 鈥楻easons to worry鈥

Conservative commentator David Frum, meanwhile, told Question Period that values-screening is worth discussing, pointing out that European countries are already doing it.

鈥淭he Netherlands since 2006 has applied a test to immigrants to make sure they don鈥檛 bring misogynistic, anti-Semitic and homophobic values with them,鈥 he said. 鈥淭he Danes have a long pattern of not allowing visas for spouses if a Dane marries a foreign national to head off child marriage in immigrant communities.鈥

Frum added: 鈥淭he world is full of people who are very different one from another and a lot of countries that have faced internal struggles and security problems, people want barriers at the border to screen out people who won鈥檛 adjust.鈥

According to him, people on the receiving end of mass immigration from war-torn countries 鈥渉ave reason to worry.鈥

鈥淭hey see the kind of security threats that Europe has so horrifically suffered from and they want to prevent it at the border,鈥 Frum added.

鈥淭he problem, of course, is that most of these threats show up not with first-generation immigrants but second-generation immigrants,鈥 Frum said.

Leitch feels 鈥渧ery strongly鈥 about proposal

Leitch doubled-down on her screening idea on Friday, issuing a press release that stated she will be 鈥減utting forward policies that will make Canada safer, stronger and that will enhance a unified Canadian identity.鈥

"Screening potential immigrants for anti-Canadian values that include intolerance towards other religions, cultures and sexual orientations, violent and/or misogynist behaviour and/or a lack of acceptance of our Canadian tradition of personal and economic freedoms is a policy proposal that I feel very strongly about,鈥 Leitch wrote.

Leitch had asked potential supporters in an email to vote on whether 鈥渢he Canadian government (should) screen potential immigrants for anti-Canadian values as part of its normal screening for refugees and landed immigrants.鈥
