Legalization of all the medical letters and reports that are issued by the Canadian hospitals and the other trusts is possible as long as they have been signed by a Canadian doctor who is registered with the General Medical Council. All those letters concerning any kind of non-medical issues like letters of employment or any kind of job reference, etc can be legalized if they are signed by a Canadian notary confirming them to be genuine and true. No other medical documents can be legalized, including the Form Med3 issued by the doctors for statutory social security and sick pay purposes.
