Prior to the election 2,300 Syrian refugees had resettled in Canada with another nearly 10,000 in the process of application as of Oct 2 2015.
Post election November 17(this is where it gets humourous) we saw this problem.
On Nov. 17, the UNHCR began sending out thousands of text messages to refugees who were already registered with the agency. Some of the cellphone numbers had changed, meaning not every text may have been received.
Of the 41,050 texts sent by UNHCR to ask refugees if they were interested in resettling permanently in Canada:
28,560 replied, and were contacted by phone to see if they would come in for an interview to see if they qualified.
3,049 actually showed up to UNHCR for those interviews.
1,801 had been referred to Canada as of Nov. 30 for follow-up interviews with Canadian visa officers.
