JLA/ avangers crossover is it ruled canon

please could u tell me if so where does it say it

i've seen this asked at least 90 times.....10 bieng from you i think 😐

Yesan old thread exists I saw during a search that proves it. I think it's a Sir Whirlysplat thread.

this particular series is most likely a yes, but typically crossovers are so exaggerated that it's a no. like the Amalgam(sp?) comics of the 90's
