@GG12345 I know implied status is a legal one- so I emailed my employer my EE AOR letter as well as the proof of application to extend my work permit. It's just that outside of Covid where renewal of health cards are being ignored, normally you find that Service Canada Reps do not know of /acknowledge implied status for renewal of docs.Just less than a week time & you will have BOWP approval. You won't go in implied status. An Implied status is legal status that employee is allowed to work, so employer must not make a big deal out of it. Anyway, health cards cannot be extended online if you were working on work Visa. Gov. already mentioned that expired health cards will work. You can check the website. So, don't worry about heathCard renewal at this point.
Just make sure you extend expiration of your SIN as soon as original WP are received. You can do it online but sometimes website is not always up but still you have another option to send the application by mail. They need ORIGINALs. It will take ~20 business days to get SIN Exp extended. Ping me if you have any questions!
Getting the BOWP in hand will be good though because I even need to send a copy to the child benefit department.
