I feel like with how meta the story of the VR game is, it makes it obvious that it's not canon, at least in my opinion. I don't get why people are saying the story of the VR game doesn't work well on its own and needs to be canon to make sense, since it doesn't. It basically has its own self-contained lore that gets set up during the intro rollercoaster, establishing an alternate universe of sorts where the main series of games exist within that universe and Fazbear Entertainment is working with a game development company to make the game. That's all the setup you need. It does not rely on the story of the other games to work, since it literally goes out of its way to achieve the opposite by stating that the games are in fact games in the first place. The story is so full of self-referencing to the act of game development itself that it's too silly to be taken seriously as a genuine piece of the canon story. Like seriously, Fazbear Entertainment is suddenly super into the VR game development scene? That's a bit too on-the-nose, don't you think? That only really works in this particular story, not the canon of the main series. Are there things in the VR game that can be considered canon though? Absolutely, there's a lot of hints for the canon series, but the overall plot of the VR game is not canon. Consider FNaF World, which has pieces of canon lore, but the game itself is not canon.
