Here’s the same Obsidian Canvas document open in Obsidian, and Hi-Canvas:
They’re not fully cross compatible, but as another user mentioned, the open source spec being worked on is picking up steam as the Open Canvas Working Group (OCWG) and even larger industry canvas platforms are trying to make the format something they can easily import and export in that open format.
So hopefully you won’t have to worry about migration much longer :)

Fwiw, they’ve open sourced the specification behind canvas, so there’s a good chance any OSS Obsidian “forks” that pop up if they do enshittify will be able to support it.
