Visitor visa for Filipina spouse

[Paragone]

Hi, I'm a Canadian, married to a Filipina who I plan to visit me with my 2 mo old son on a tourist/visitor visa while we await the processing of partner visa.

She has ties to her home - a paint/hardware store, some properties(including a commercial lot), as well as a son from a previous relationship whom she shares custody of.

So, is there anyone here with some experience that might say something about her chances of being accepted for a tourist/Visitor Visa?

How much money will she need to show in her account(and I in mine)?

And is there any general advice I might follow, or convey to her, on navigating the application/interview process?

Also, does anyone have an opinion on whether the sponsorship process would count in her favor of being accepted(for a tourist visa), or against it?

Thanks.
