Thank you for replying, but before i saw the answers i contacted CIC and they replied:
Sir, Madam,
Thank you for contacting Citizenship and Immigration Canada. I am pleased to follow up on your request:
Extension - Same employer
As a live-in caregiver, if you have been in Canada under the Live-in Caregiver (LCG) program for less than four years and you continue to work for the same employer, you do not need a new Labour Market Impact Assessment (LMIA) from Employment and Social Development Canada when applying to extend your stay in Canada as a worker.
Please note however, that you need:
A new LMIA, even if you are staying with the same employer, if you have participated in the LCG program for four years,
A new WP and a new LMIA if the employer moves and changes province/territory.
you want to continue working for the same employer, you need to get:
A letter from the employer stating that you will continue to be employed on a full-time basis for an additional period of time,
A copy of a new, or extended, signed employment contract, and
For live-in caregivers working in the province of Quebec, a Certificat d’acceptation du Québec (CAQ) from the Ministère de l’Immigration, de la Diversité et de l’Inclusion (MIDI).
I hope this info herlps not only me. Thanks
