Now we see through a glass, darkly...

I've never seen Canon refer to an ILC as "weather sealed". They use the term "weather sealing" a lot to describe a camera's parts, but they don't ever call those cameras "weather sealed." They call their cameras "dust and weather resistant", they don't call them "dust and weather proof."It's interesting to hear of "weather sealed" claims by various manufacturers. The reality is that some are incredible, most are adequate if you don't keep them in continuous rain, and some are downright lying.
I have an Olympus EM1mark2 and pro lenses. If you bet me some big money if I dunked it with lens into a toilet or swimming pool and it'd still work fine, I'd take your bet and it'd be fine. They're one of the few(maybe only) than went truly overboard in weather sealing. Too bad the sensor is so small and so old (even in the mark3).
Sony is the opposite. From what I've read, they often don't even have a rubber seal around the lens mount that actually touches the camera mount when connected. Their bodies have sometimes been found to let in large amounts of water at various places.
Canon seems to have a very good reputation for sealing, but not to the point of daring to do complete immersion. I'm very much looking forward to getting the R5 and some L lenses.
No matter what the sealing quality, I don't use the camera in the rain, period! But if I get caught in the rain before I can put it away, it's good to know it'd be safe.
