Landing on FSW visa (Question)

Hi folk,

I have a visit visa to Canada where I am planning to visit for the purpose of attending a conference in February for only a few days. If my PR visa was issued by then, would I have the choice of postponing landing (planning to do landing in June)? If so, is there anything or any procedure I should be aware in terms of arriving on a visit visa whilst simeltaneously carrying a PR visa?

Any thoughts? Anyone?
