I need to ensure the whole divorce process is legal and does not affect my citizenship pathway for Canada.
As a foreigner, I understand legally I need to "tell the Home Office when I divorce or separate from my partner if my visa is based on our relationship" (https://www.gov.uk/visas-when-you-separate-or-divorce), then the Home Office will "tell me when do I need to leave the UK".
My questions are:
1) Do I inform the Home Office of divorce immediately after applying for divorce online through gov.uk, or after getting the decree absolute (officially getting a "divorced" status)?
2) It takes at least six months to get the decree absolute. If I need to inform the Home Office immediately after applying for divorce online through gov.uk, and they only give me a short time to leave the UK, will i be able to finish all the remaining steps (until getting the decree absolute) in Canada?
Have to make this post because I called UKVI twice for this issue, they gave me two completely opposite answers on the first question.

Thank you.
