If we get the pr application approved, then i can apply jobs via online? I still dont understand what this application will do to help to work and stay in Canada..If you got your COPR / PR application is approved. You can check all the pre arrival services at www.cic.gc.ca/English/newcomers/before-services.asp
You can choose any of the pre arrival service based on your choice and attend. This would help you in getting prepared for the job market. This is the harsh reality you can not get job from India. You need to come to Canada and apply for jobs here personally and attend interview to fetch the employment.
If you find any job search service or pre arrival service charging money. This is SCAM. Pre arrival service are free and funded by government of Canada. Hope this helps
