For caregivers, previous LMO's had an expiry date on the back of the LMO approval sheet? Apparently now they don't put expiry dates on the LMO approval sheet any more. I was told by HRSDC in Vancouver that they go by the work permit expiry date. They also said that a new LMO has to be submitted to change employers or to extend existing contracts. I contacted CIC and they said a new LMO is not required to extend caregiver contracts; only to change employers. HRSDC said that the employment situation is changing day by day because of the economic situation and to check back often on LMO requirements.
