There is no fee for a new Ontario health card.
To change your name on your health card, you must visit a ServiceOntario and bring a completed Change of Information form (0280-82e) as well as an original copy of one of the following documents:
Since June 2016, sex designation is no longer displayed on Ontario health cards.
Since August 2022, you can now add French language characters to your name on your Ontario health card. To request a new health card with French language characters in your name, visit a ServiceOntario location with documents proving your legal name and showing those characters. If your Canadian citizenship or immigration document does not show your legal name with French language characters, you may be able to provide another proof of residency or identity document that does.
