Was this car drowned?

Canadian spec Tundra, I get that in Canada they spray salt on their roads due to snow. What caught my eye is the rusting in the engine bay, not just that, but the small stains of dried water on top of the air filter and fuse box. What could possibly cause that rust in the engine bay? It’s a 2018 SR5 with 139k KMs on the odo, non rolled back.
