It wouldnt matter if the application is sent outland. Trips outside Canada has no bearing on PR application process, especially if sponsor is Canadian. If sponsor is PR, then PR is to remain in Canada during PR application, inland or outland. So the longer PR sponsor stays outside Canada, the more chance the application get rejected on account that PR is not staying in Canada as required. Thus leaving Canada on short trips up to 3 weeks Max is tolerated since considering typical vacation time 2-3 weeks. Going beyond 3 weeks, may bring doubt to CIC on whether you as PR is honouring the stay in Canada rule.
However if the application is sent inland trips outside Canada can effect outcome of application. The longer the sponsor or applicant stays outside Canada during inland, the greater the chance, application get rejected. Even more so for applicant if she/he gets denied back into Canada upon re-entry, the application becomes dead in the water.
