Do you need a regular visit before getting approvedfor a PFV? particuarly Grande Cache Institution

If you are not married or common law, then yes. Most places want 1 year of regular visits first.

so if you are common-law...?

Here is the CD on it, a great source of info. I think its best to have some regular visits, especially if there has been any turbulence in your relationship that they know of. But I dont think it is mandatory.
