While I will talk to 1 lawyer today, re-applying is kind of not what I am thinking. If I can re-establish that I am going back to Canada and get Ohip, that shows I am serious about moving back to Canada. I would rather be with my family. Let the appeal process move forward.
...I really cant imagine reapplying while I live overseas and I will not move to Canada on my own. lets see from lawyers if there is a way they can approve TRV even though spousal was declined.
It is all up to you, of course. Sure, talk to a lawyer. Think whatever you like.
But I repeat: for the most part, from what we have seen here, appeals seem to consistently take longer than re-applying. Perhaps there are exceptions, I have heard some claim to have written and requested 'review', never heard of one being accepted that way (i.e. IRCC reversing course once a decision has been taken).
TRV: obviously one question is to wait and see if current app gets accepted. I would hope it would given that you have two citizen-children and understandable they would want to visit Canada with mother. Has your spouse ever visited Canada / held a visa to USA/EU etc?
As for being apart: my suggestion of returning first is function of the fastest way of moving forward including being together again (with shortest period apart) - referring only to spouse as kids can travel at will.
In order of rough minimal-time apart from scenarios I referred to:
[well obviously if you refuse to leave and just re-apply and wait or decide to go to USA, you won't be apart]
1 - if TRV is approved right away, you all go to Canada and apply inland ASAP. This is likely also fastest way of getting PR approved.
2 - if not approved and you go to Canada, apply outland on arrival and then re-apply for TRV once AOR is received (about 30-60 days). That might mean spouse can't join you for 60-120 days if TRV approved.
3 - if TRV declined, perhaps 6-12 months wait (although can re-apply for TRV). Some chance it might be faster as likely they did some/much of the checking of your spouse.
Again, up to you. General comment: don't try to make decisions while angry about this (it happens). Regardless, if / when you reapply, you may want to get others to review your submission: to me your long paragraph above was confusing with a lot of irrelevant details.
Keep it short, succinct, simple story - focus on verifiable dates and details, use bullet points. To me the essential elements of your story and proof of plan to return to Canada are:
-After residing abroad for some years, you were in process of re-establishing yourself in Canada in 2018-19. Covid caused you to leave Canada because of children and spouse and obviously travel was limited.
-You will support yoursefl and your family by running the same online business you have now.
-You have not yet moved back only because of spouse and two young children.
-Emphasize also TRV application for spouse, mention family reunification.
-You have the means and can show that you will/have rent(ed) a place when needed. Show other arrangements (bank accounts, schooling, moving stuff, etc). [Obviously I don't know details of what you did before]
-It will help if you set a date you plan to move (eg to 'prepare for spouse' and kids by arranging business), and then do it (advising IRCC after the fact) if not approved by then.
Good luck.
