From the Canon site:
The Canon Rebel T3 will work with pretty much any EF-mount lens ever made, as well as with the EF-S lenses designed for cameras with APS-C size sensors.
The Canon 90D has a Canon EF/EF-S lens mount and currently there are 333 native lenses available for this mount.
I own a 90D and use native EF and EF-S lenses. That being said the lenses you currently own should work on the 90D
Be a different person on the web, be kind, respectful and most of all be helpful!
90D ~ 5D Mark IV ~ R6 Mark II ~ R50 and way to many lenses
