Is Southern Ontario becoming humid subtropical over time?

It's a really interesting zone area that gets little attention for the potential of a mix between the oaks, beeches, hickories and the pines, laurels, and hollies. Despite some people liking the totality of a perfect broadleaf evergreen ecosystem, you notice that central and eastern VA are very special areas indeed, despite it seeming like it's temperate on the surface.

What some people want a subtropical climate to be is all the characteristics of a tropical climate but with a lower minimum temperature limit than 18C. Seems like an extremely narrow way to classify what should be a massive group of climates. All transitional areas will have a mix of native flora. That’s why I think the Carolinian forest eco zone you describe is a good indicator at least on the east coast of North America. It’s the point past the mixed wood plains where broadleaf trees become more dominant and there’s more and more animals you don’t see further north.
Deciduous forests exist in tropical savannah climates as well so I really don’t like the idea that deciduous=continental.

It's funny, in Augusta quite a bit of our deciduous vegetation is from tropical/subtropical Asia that's naturalized.

Crepe myrtles are planted throughout the entire southeast and are well known but there's also the chinaberry tree(melia azedarach) that is numerous here in Augusta, I have a large one growing on the side of my house. They have that feathery, tropical leave look, it is only really hardy to about zone 7b/8a so it's deciduousness is not due to being cold adapted.

Another common asian plant is the mimosa tree, jacaranda trees can't be grown here(long term) because they are a tender zone 9 plant, there's many, many more tropical deciduous plants.

Tropical savannah biomes are notorious for having deciduous trees, due to a difference in precipitation than say temperature, but in places like Thailand, November-March doesn't look that much different for some areas.
