as i said, applying for outland sponsorship will not make your fiance eligible for owp. unless you are, for example, an international student or a worker with a certain noc code employment, she can apply for sowp. she should be here in canada at least on a visitor visa living with you when you apply for inland spousal sponsorship. and you can't apply for owp before you apply pr inland sponsorship for her. as soon as you get married, declare her you wife so you can sponsor her. if not, you will be misrepresenting and you can't sponsor her to come to canada.
she can apply for sowp depending on your status though. i'm just pointing out that you can't go through the outland sponsorship route. we are in the spouse open work permit thread, maybe someone can help you if you explain more about your status here. idon't know much about sowp. sorry.
