I am also not well experienced with a standard vehicle nor working on it myself, so investigating the issue has simply been me attempting and successfully recreating and identifying how the rattle happens.
Have also taken it to Toyota and they couldn't recreate it, even after I drove with their "lead" technician and displayed the rattling sound and confirmed that he heard it. Will be trying to go to another Toyota after this weekend, but busy schedule.
The Issue:
The rattling sound happens under specific circumstances only, and I had discovered it while driving normally to and from work. The rattling sound happens only while the car is moving, in gears 2-6, under some kind of load (light - heavy), at the specific range of 2.1k - 3.05k RPM and only while the throttle is being depressed (either a fast press, or light tap to simply maintain coasting speeds.).
The volume of the rattling sound can also vary, I can make it louder or quieter depending on how heavy I press the throttle, also the rattling sound sounds like it is coming from the front half of the vehicle, mostly the engine bay area I suspect, but being limited on where I can sit to hear the noise I cannot pin point exactly where the noise is. It also sounds something close to metal hitting metal, and can be heard more vividly with the windows down, but does not limit the rattling sound to being heard while the windows are up, it simply sounds like a slightly muffled version.
Any suggestions would be great, I have done most of the things in my power, which isn't really much, to find and narrow down the problem.
Edit: To give an idea of how new the car is, I have 5400 km on the Odometer in my month and 3 weeks of ownership.

Edit 2: (Nice bold red edit for just for hum!)
Bringing this thread back up because the issue still exists, but I have an interesting update. Odo is at 8100 km.
Went to two different dealerships on the 13th of September and the 27th of October. First dealership was useless, the second dealership fully acknowledge the sound and has deemed it an issue, but they have no idea what it could be and any guess atm is just a long shot. Interestingly though, when I had gone in and explained the issue thoroughly, they were able to hear the sound without me needing to drive it to recreate it.
ALSO, big big also, there was another 2017 86 in for the same issue, but not until I came in and explained exactly how to recreate the sound, were they able to create it.
I don't believe at all that this sound is normal because of how harsh and loud the sound can be, and how specific it is to a certain rpm range.
I have also contacted Toyota Canada about this issue, and it will likely get escalated.
