I know the f4 Skyray, but this isn’t quite it, googling a twin tail variant gave me nothing, what is this?

Hello I was wondering if anyone would be able to help me figure out what plane this was?
I was driving in Kitchener/Waterloo, Ontario, Canada
It was distinctly tan and was notably kind of boxier than most planes and I figured it was a military plane.

No flight trackers have a plane matching that description and while parts of my description may be iffy, it was 100% tan in colour and didn't seem like a small plane.

Thank you!

UPDATE: It seems like it was the CL-415, it being foggy out was likely what made it look a solid tan rather than yellow
