With this for, filled by your GP, you can get all your ID changed to show the gender you wish.

With this SECOND form added you can get your bc medical card changed.

With both forms, and application for new Drivers license / BCID / BC Services card(s) completed, you only need to send a letter to ICBC head office requesting they amend all your drivers records to remove old names.

That information is contained in a letter ICBC has not made findable on their website, but they do have the steps needed for the name / gender change detailed
