I have exact same profile as you. I got same email saying your file is in queue to process, but doesn't say it may take month as far as I know they don't write such a things. Few things I wanna tell you, you should apply work permit extension paper file it takes 4-5 month to process with a letter from your employer by this you can work on implied status, moreover you will comply with Bc pnp requirement which is retain employment status while your file is getting processed at any cost you shouldn't leave a job. BC pnp taking 4.5 months for processing a files rite now as my consultant talk to BC PNP. So you must be getting pnp next week for sure if they didn't object anything related to you employment. One more thing you can read requirement of work permit supporting letter it clearly says we will issue you a work permit supporting letter if you applied to CIC with letter from employer.
Thanks
