Canada said Tuesday that it will resettle 10,000 Syrian refugees by the end of 2015, aiming to increase the number to 25,000 by February.

The Washington Post reports that Prime Minister Justin Trudeau aimed to settle 25,000 refugees by the end of the year, but faced opposition following the Paris attacks on Nov. 13. According to Immigrant and Refugee Minister John McCallum, the Canadian government wanted to start the resettling process quickly, but also wanted to make sure it was done correctly. Doing so would require more time.

The Canadian government will enact “robust health and safety screening” overseas. Refugees will be transported by a privately charted aircraft, with military assistance when necessary, beginning in December.

In the United States, many governors have publicly stated that they do not want any Syrian refugees resettled in their states. A commitment is currently in place, in which the United States will accept 10,000 refugees into 2016.

Canada is preparing military barracks as a precautionary measure should temporary housing be needed. The resettlement effort is expected to cost around $510 million, over six years. Canada has a history of accepting refugees, quickly and in large quantities. Over 1.2 million refugees have made their home in Canada since World War II, coming from places such as Uganda and Vietnam.
