OTTAWA -- The Canadian Press has learned the cost of the Liberal government's plan to resettle 25,000 Syrian refugees is pegged at $1.2 billion over the next six years.

A government document obtained by The Canadian Press that lays out the proposed funding model says $876.7 million would be needed in this fiscal year alone.

Some of that will be covered by $16.6 million already announced by the previous government in September and $100 million that would come out an existing pool of funds to respond to international crises.

The document suggests the Immigration Department would need $528.4 million this year, and Defence $98.7 million.

What's not clear is whether the cash relates to the year-end target to bring in that many Syrians in total or the Liberal's promise the government itself would settle that many over a longer time period.

The Immigration department refused to provide any detail, saying they do not comment on leaked documents.
