i live in USA and my spouse live in Canada and she holds PR in Canada.
Can she move to USA next day after applying my spouse sponsorship PR visa in Canada ?
Can we go back to Canada once my spouse sponsorship PR visa will be approved ?

No - she can't. Since she is a PR, she must live in Canada while your application is being processed. Short trips outside of Canada (e.g. two weeks) are fine. But moving to the US is not and will most likely result in your application being refused. Only citizens are allowed to sponsor while living outside of Canada.
