You should not have a problem - if you have been granted PR status you are free to move and work anywhere in Canada.
The H. John Mccallum, when interviewed in CTV Atlantic (that was a few months ago - there was a meeting on proposals to revise some immigration policies in the Maritimes) - was asked directly if there was a way to divert new immigrants to provinces where immigrants are needed - rather than allowing them to congregate to populous city centres and provinces. The reply was the Constitution, specifically the Charter of Bill of Rights, protects the mobility freedoms of citizens as well as permanent residents - so immigrants cannot be forced/restricted to settle in a particular area.
Note on the last statements - currently the mobility rights are protected. However, for the past few years - there has been increasing clamour - from Provinces would benefit from in-migration - for any solution to retain immigrants within the provinces including federal legislation. So far, no firm proposals on how this will be done.
If you do move, expect a survey to be sent to you asking reasons why the move was made. This is all information gathering, presumably in aid of needed changes to the current provincial immigration programs. It may be added to data to show the case for restrictions to be put in place.
