So Mario Is Missing is not canon to the games for a few reasons.

The main reason is Mario Is Missing contradicts the current canon of the Mario games. So in the manual for Mario Is Missing it says the following. "Will the brave brothers from Brookyln permit this abominable snow plan?" This is the Mario is an Italian American Immigrant from Brookyln origin that was never stated in any confirmed canon game or manual. This is not canon to the games continuity and is only canon to the Movieverse and Supershowverse. In the games Mario is a native son of the Mushroom Kingdom and immigrated to Big City as some point.

Also, this game alongside other games like Hotel Mario is probably on the same level of canonicity as the Supershow. This is because Nintendo basically licensed the characters to Toolworks, while Nintendo's staff and even Miyamoto did not have any hand in it. Note that even games like Super Mario RPG: Legend Of The Seven Stars at least had input from Nintendo's staff like Shigeru Miyamoto. With Miyamoto saying it didn't make sense for Mario to be riding a horse and wielding a sword, but rather to be riding Yoshi and wielding a hammer. This would probably put Mario Is Missing on the same level as the Supershow canonicity wise, and the claim it's always the same Mario wouldn't apply to this game.

So Mario's Time Machine is game people consider to be canon but I believe it is not canon for a few reasons.

One reason is Mario's Time Machine doesn't really fit well in the Mario timeline. It doesn't make much sense for Bowser or Mario to have access to time travel this early in the timeline. This is because the creation of E. Gadd's time machine in Mario & Luigi: Partner's In Time is treated as a major event to the extent there is a Lakitu Bros. news report on it. So it doesn't make sense for Bowser and Mario to just so casually have a time machine before the events of this game. Btw, Dr. Crygor probably developed his time machine tech separately and wasn't talked about since it was in Diamond City.

The second reason is this game alongside other games like Hotel Mario is probably on the same level of canonicity as the Supershow. This is because Nintendo basically licensed the characters to Toolworks, while Nintendo's staff and even Miyamoto did not have any hand in it. Note that even games like Super Mario RPG: Legend Of The Seven Stars at least had input from Nintendo's staff like Shigeru Miyamoto. With Miyamoto saying it didn't make sense for Mario to be riding a horse and wielding a sword, but rather to be riding Yoshi and wielding a hammer. This would probably put Mario Is Time Machine on the same level as the Supershow canonicity wise, and the claim it's always the same Mario wouldn't apply to this game.

The Final reason is Mario's Time Machine contradicts the current canon of the Mario games. Mario tells Kublai Khan that he is from Brookyln while Kublai Khan says he sounds like he is from Italy. "Brookyln? Bah! Your accent betrays you! You are obviously another bold explorer from Italy!" This is the Mario is an Italian American Immigrant from Brookyln origin that was never stated in any confirmed canon game or manual. This is not canon to the games continuity and is only canon to the Movieverse and Supershowverse. In the games Mario is a native son of the Mushroom Kingdom and immigrated to Big City as some point.

So I decided to create a list of the various continuities of Mario as well as give them names. This can serve as a way to help discern what is and isn't connected.
