Changed name through Deed Poll in the UK? Do i need to get it apostilled?

[KingGnar34]

Hello,

I changed my name about 3 years ago in the UK by deed poll (got it signed by a solicitor and everything official), my new passport, documents, everything is in my new name.

I plan to apply for the IEC starting next year but worried my name change may cause some issues....
Ive been told I need to get my deed poll apostilled by the Canadian Embassy in London, at what stage would I need to do this, during the IEC application?

Does anyone have any experience or advice? Thanks!
