Lol I am AOR May, 2018. Security started in June, 2018. CSIS sent report back to CBSA on January, 2019. Now security final check is pending with CBSA eversince. If you are under security screening it can take anywhere from 6 months to 24 months or even more, so there's no timeline. Contacting MPs, Ministries, IRCC, CBSA, CSIS, ordering GCMS nothing can help you unfortunately.
