I will add one very specific warning: the PA applied to enter as a farm worker (work permit) and was refused in June 2018. (As well as a TRV refusal in Dec 2017).
From the dates and timeline above, it is very clear that the PA and Sponsor's families had initiated contacts about finding a match as early as Jan 2018, and meetings between the families occurred in January and the sponsor and PA in March, 2018.
Therefore there is at least the appearance/potential that the PA applied for the WP at a point when betrothal discussions had taken place. (Info above does not indicate exactly when the WP application was made though).
If this information was left out of the WP application, there is at least the potential that IRCC would consider this misrepresentation. Misrepresentation can have very serious consequences, including being deemed inadmissible. This could be the case irrespective of whether they decide the relationship is genuine.
(Since there were concerns about the TRV apps as well, you'll need to look at those carefully as well)
You need a lawyer - a good lawyer. I'm not saying 'you need a lawyer' in the sense of 'to help you prepare for the interview,' you need a lawyer because you potentially will be subject to a ban on entering Canada. You may think it "doesn't count" or some other explanation because you weren't married yet - that is almost certainly wrong; leaving out material information is misrepresentation.
Note, I'm not a lawyer and I'm not an expert. My comments here could be wrong (and I doubt I have all the information anyway). But this is quite serious, I believe.
