As refugee experts continue to suggest the Trudeau government won’t meet its goal of bringing 25,000 Syrians to Canada by Jan. 1, CTV News has learned the Liberals have already started to bring them here.

Sources told CTV’s Ottawa Bureau Chief Robert Fife that the plan to take in the full 25,000 will be rolled out as early as next week.

Some of the refugees will have gone through medical and security screening by the United Nations, and others will be screened on military bases once they arrive in Canada, according to the sources.

Cities and provinces will help with accommodations, they said.

Peter Showler, a former chair of the Immigration and Refugee Board, said preparing military bases and lining up accommodations in municipal locations will take longer than the several weeks left in 2015.

“It’s going to take three or four months in order to efficiently distribute those refugees into communities across Canada,” Showler told CTV’s Canada AM Thursday from Ottawa.

“They can do it, let me be clear, it’s just going to take time.”

Showler said the new government is doing “a tremendous job” trying to fulfill its promise of resettling these refugees, but they shouldn’t “fixate” on their self-imposed deadline.

“I just wish the minister would stop talking about the end of the year,” Showler said of Immigration Minister John McCallum.

Once immigration officials have brought the refugees over, Showler says there will be still be lots of work left to do.

Many of the new arrivals will be families with children who will need to be evaluated and placed in schools. Many will also need English training. Some could also have medical or dental needs that haven’t been addressed during their months or years in refugee camps. And there will be many who will also be eager to find work and open bank accounts.

“On top of that is all the paperwork -- and there’s a tremendous amount of paperwork,” said Showler.

Canada “does a very good job at settlement,” he added, and there are already lots of agencies across the country that can help the new arrivals.

But, he said, the federal government cut funding to many of these agencies in the last few years, leaving many underfunded.

Now, these agencies will be asked to help resettle these 25,000 Syrians on top of the 13,000 refugees they already help each year.

“This is going to be a tremendous challenge for them.”
