Oh yes I remember you now. As you know, technically you don't need authorisation if you applied together according to IRCC's website. A few people have also confirmed that they travelled with accompanying visiting visa with no authorisation. However, IRCC told me that I needed one for my son who has only a TRV and we applied together, so it's hard to know what to do.
Can you send a follow up email to:
ircc.covid-travelexemptions-exemptionsdevoyage-covid.ircc@cic.gc.ca or try to contact your local IRCC office if you know which one it is.
