Metro Vancouver is still loosing residents to the rest of the province and rest of the country, and allot of them. The city of Vancouver is hemorrhaging residents. New provincial stats will be out shortly.
BC is big and this year there will be many BC residents returning home after losing their jobs in Alberta. Most of these people will be returning to cities in eastern and northern BC. Not to metro Vancouver, thats a place to leave for long time citizens / residents.
