I have not had a chance to look into your suggestions, I will later today, but meanwhile want to advise that the strata has a by-law on short term/holiday rentals which states that an “occupier” of a lot can engage in short term or holiday letting. There seems no restriction on the “occupier” regarding how many can dwell on the premises or for how long it can be let out.
How about you answer the first response before embarking on another line of inquiry? This is hardly urgent and that would be the polite thing to do.
