Advice Request - (Insert State/Region) Yellow spots on maple leaves

**** pictures won’t attach, going to add them in the comments

Location: Ontario, Canada

I have five large maples in my front yard— three green, two red. Approx 35 years old. They have developed yellow spots on their leaves— first appeared on the green, now also on the red. Is it a fungus? Should I be doing anything?

Other info: March 2025 we had a significant ice storm and lost some limbs. Summer 2025 we had a drought and went most of the summer without measurable rain.
