Once you are a PR, you are free to move to any province anyway.
You definitely can sponsor her, inland or outland, once you are a PR. However, if you already reached the common-law status (living together in a marital relation for 12 consecutive months) before you land as a PR, then you have to declare her before landing otherwise you will never be able to sponsor her. If you did not reach common-law status prior to landing, you have nothing to declare and you will be allowed to sponsor her after either a marriage or after reaching the common-law status.
