There is no dependent visa. Your wife should be applying for an OWP and hour child should be applying for a TRV. Some companies seem to incorrectly apply for TRVs for spouses. Every visa/permit has different processing times so you will all have different processing times.
Thanks everyone for your reply.
As suggested, I have reached the visa team in my company. They are telling my application is already been filed in IRCC. But I am worried why I didn’t received my BIL.
I never know it would take this long for me to even do biometrics. Needless to say about the processing time.
I just checked in IRCC and found this:
We’re currently finalizing most applications we received between
November 29 and December 5, 2020
If your application is complex, it may take us longer to process it.
