I don’t know the full details for online applicants, you might want to search here and see what people have said. I have found this on ORCC website though:
“Electronically sign your application
- You must type your full name exactly as shown on your passport to electronically sign your application.”

And this here:
“Signatures
If signatures are missing, we will return the application without processing it.
Note: IRCC will normally accept forms with photocopies of signatures. However, you may be asked to provide the original copy of your forms with an original signature if an IRCC officer determines it is necessary.
- Remember to check for a signature block on each form and sign when needed. If forms are not signed in the correct places, and by the correct people, we will return your application without processing it.
- Signatures may be required in more than one place, or by more than one person on some forms.
- Where a date is needed, make sure you complete the section.
- A parent or legal guardian must sign on behalf of a dependent child under the age of 18 when a signature for this person is required.
Important: Use the last page of your checklist to help you make sure all forms have been signed correctly.”
