I'm in a similar situation. I applied in Nov 2021, and the background check started in May 2023 - it's been almost 3 years now. Everything else is completed except for security screening for 1 parent.We have tried via MP too, they simply confirmed what we knew that file is stuck in comprehensive security reffered to CBSA. I have talked with few people and everyone said it takes around 18-24 months after file is referred. Btw my parents were working in Indian Railways. Getting a bit worried as it is taking very very long time.
