Or more simply, they're not what he would have done so they're just this side thing that exists. It's not something he is going to concern himself with if writing new material. What HE wrote is what Dragon Ball is to him. Everything else is a side-story or a parallel universe sort of thing. It's pretty much as simple as that.
You can go round and round arguing it, but I doubt Toriyama has given it any more thought then that. I certainly don't think he was thinking, "It's canon but only to the anime" or something. At the same time, he is respectful of other people's ideas and work put into his creation... so he's not going to say anything necessarily negative about those things either.
That's all well and good, but, as I've mentioned numerous times, it's not what this thread is about.
GT's status as a side story is in no way a reflection of it's canonicity, as , by their nature, side-stories are not inherently "non-canon."
You can come up with as many valid reasons to declare GT "non-canon" as you want, but it's status as a side story is not one of them.
Another point, Toriyama doesn't have the authority to declare Dragon Ball works non-canon. He is not the sole author of the works in the franchise, nor is he the sole owner of the franchise as a whole. That would be like Stan Lee suddenly declaring that only the comics he wrote for Marvel were official continuity; regardless of whether or not he created the characters and the stories, he doesn't have creative control over them anymore.
