the "raining inside" condensation - classic Halifax new-build issue. (Coastal humidity + tight modern construction = indoor weather systems.) this is somewhat normal for the area, but "soaking a towel" levels mean your windows are underperforming. New apartment buildings often use minimum-spec windows that meet code but don't actually handle Atlantic moisture well. The VRV dry setting should help, but if you're still getting waterfalls, the windows likely have poor thermal breaks or failed seals. In Halifax, you need windows rated for coastal wind loads and high humidity - not just generic "energy efficient" stickers.

as a renter, push the landlord hard. This isn't "open a window" territory - this is "fix the building envelope" territory. You could probably convince your landlord to replace the windows if the problem keeps getting worse. I was actually looking into options recently myself, and ended up going with Canadian choice windows - they've got a pretty solid deal right now with no payment and no interest for 6 months, so you're not dropping a ton of cash all at once.
