I'll try to hit on a few points in relation to your question.
First and foremost, we work extensively and closely with all our domestic partners. That's where it begins for us.
Once IRCC has selected some individuals as potential refugees to Canada and we receive those referrals, we then engage with all our law enforcement and security partners to make sure we do our due diligence domestically.
For sure we work with international partners. CBSA doesn't have a presence in Iraq, but liaison officers have been deployed to Amman in Jordan, and we have one in Istanbul, Turkey. They are responsible for the geographic area.
Due to the current situation in that area, we have not deployed a representative in that country, but we do work with those state entities through the missions to make sure that whatever is required in co-operation, information, and any type of facilitation is secured as part of these undertakings, as we did for Syria, to ensure that we're able to deliver on the screening mandate as well as facilitate IRCC in reaching final determinations on selection.
