Well, no. I mean, Generations' canonocity to the main series Sonic titles is about as ambiguous as the Riders games, and Sonic Battle, but I'm just gonna tip my hand, and say that Generations may be canon, but the levels that were included were the results of fan-input, meaning that it's a gameplay prop that doesn't hold anything on the story
