Welcome to the forum! As has already been said, you should consider a full sized truck to tow a 23. We don't actually have the final numbers for the 23 yet, but we do know they'll be substantially higher than the 21. Based on that, even if you manage to get the numbers under the published maximums, a Canyon is going to have a tough time towing a 23.
Just for some anecdotal perspective, my F150 is capable of towing a trailer twice as heavy as my 19. Some say it's "overkill" to tow a 19 with a full size truck but after 6 plus years with this combo, I'd never consider going smaller.
