Many Americans are properly fretting this holiday season over some 10,000 Syrian migrants President Obama plans to accept over the next year, but few are aware of a developing refugee threat to the north.

The Canadian government plans to take in 25,000 Syrians by the end of February, directly jeopardizing the security of the United States. Once these Syrians are resettled in Canada, there is little to stop them from strolling into U.S. territory, where the border is far longer than in the south.

The Canadians are leaving much work to the United Nations.

Canadian resources to investigate the refugees are far inferior to those of the United States. But even American officials say we can’t easily vet the far fewer number of Syrians the United States plans to take.

FBI Director James Comey admitted in October that records may be impossible to come by.

“If someone has never made a ripple in the pond in Syria in a way that would get their identity… In our database, we can query our database until the cows come home, but there will be nothing show up because we have no record of them,” Comey said.

“With the sale of thousands of false Syrian passports — that German intelligence admits are being used to come into Germany — there is no way to know who is who,” according to Middle East and terrorism expert Abraham Miller.

What’s more, the Canadians are leaving much work to the United Nations, relying in part on background checks by the U.N. High Commissioner for Refugees (UNHCR) that are performed in the refugee camps.

The effective collapse of state infrastructure in Syria, not to mention the brutal civil war that continues to ravage the country, means any biometrics the UNHCR manages to get its hands on “are worthless and can’t be tracked,” notes Marguerite Telford, director of communications for the Center for Immigration Studies.

Proponents of Canada’s resettlement plans insist that taking refugees from camps in Turkey, Lebanon and Jordan is safer than selecting them from the hordes overwhelming Europe, but those refugee camps have long been infiltrated by ISIS and are fertile recruiting grounds for the organization. This is especially true in Turkey, which maintains the questionable policy of allowing fighters to travel freely across the border to the camps and then back to Syria.

The Canadian Broadcasting Corporation says the Canadian government initially planned on excluding single men from the refugees it accepts, taking in only families, but expanded its plan to include “women at risk” and gay men and women.

But these sorts of restrictions are a tacit admission by the Canadian government that its vetting process is inherently flawed, according to Miller.

“If it were fool-proof, they’d take the single (straight) men as well,” he pointed out.

How Canada plans on getting allegedly gay Syrians to prove their sexual proclivities is anyone’s guess. But even homosexuality isn’t necessarily a guarantee against extremism. Reports have surfaced that Paris attacker Salah Abdeslam is an active homosexual, according to Breitbart.

While not known to be as permeable as our border with Mexico, the U.S.-Canada border “is actually very porous,” according to Telford.

“A 2011 GAO report revealed only 32 miles of the border is properly secured, and apprehensions at the border increased from 1,700 in 2011 to 3,000 in 2013,” she said.

At 3,987 miles, the U.S.-Canada border is roughly twice as long as the border with Mexico, yet it is patrolled by a mere 2,200 agents. Almost 1,000 miles of it are overseen solely by unmanned drones. The National Border Patrol Council has said at least 2,000 more agents are needed to properly secure the northern border.

“The reality,” Miller said, “is that governments make choices in terms of values and risks, and the Canadian government has chosen what it sees as compassion as worth the security risk.”
