Short additional comments as I had not focussed on the issue of threats:
1) Getting a lawyer makes sense for the divorce and other aspects. The lawyer should be consulted for this aspect as well.
2) Be sure to include information about the threats - and especially for example concrete information about reporting it to the police, your lawyer, help you have sought from any party, etc. - to IRCC when reporting the case.
The chances that IRCC will devote resources and pursue the case are MUCH higher if there are specific allegations of threats being uttered, abusive behaviour, etc. It raises the case above a potential presumption that this was just a marriage that broke down - as well as making the public interest in targetting individuals for removal that represent threats to the safety of Canadians.

A lawyer will be better placed to comment, but taking into account @Kabigin 's comments above, I would note that even if the evidence re: threats is insufficient for police to pursue further (as a specific charge of either threats or extortion/coercion), I believe it can still be taken into account as part of totality of evidence regarding immigration fraud. So reporting to police and/or making this aspect clear to IRCC (eg with help of lawyer) has an impact.
One caution: I underline again that from government perspective, the 'immigration fraud' aspect is mostly not considered a 'fraud' against the individual but against the government (mostly under the misrepresentation parts of the statute). [I'm not using the term fraud here in a strict legal sense.] The one does not exclude the other, of course; but they also may have different standards of evidence and implications, that may make eg an eventual removal / exclusion from Canada possible or easier even if no criminal charges. But note, that is government of Canada pursuing what it believes to be the public interest and that may be very different from what the individual may want or expect.
Good luck. I expect most other aspects of the case are case-specific and depend on facts and circumstances that can't be fully known here and need to be discussed with legal counsel.
