To clarify my question, I want to declare my dependents as non-accompanying in the application. I have got my queries answered now by santhkum90. The reason I want to do is because it costs less and it will be much easy for me to find a job and settle down here rather than bringing my dependents along to a new land and culture. The answers here show that it is not that good an idea.
You need to understand that it will likely take about a year to sponsor your family. During that time, you MUST be residing in Canada. There is little chance of your family being approved for TRVs. You can take a few short visits, i.e. a few weeks a few times a year, but anything more risks the PR app.
If you are prepared to be separated for a year, then you can do it your way. However, it would be far simpler to include them as accompanying now and have them land and return to your country to wait while you settle down here.
