I shoot video with the original Canon C100 and would like to be able to edit the files on iPad Pro or my iPhone . I can do that easily with video files from Canon DSLR cameras and Gopro etc.. How can I import my Canon C100 AVCHD files to my iPad Pro and begin editing the files ? Thank you

Hopefully we'll hear from someone else with more experience than me, but I believe you'll need an SD card reader that connect via the Lightning port, plus a copy of Luma Fusion: https://luma-touch.com/lumafusion-for-ios-2/

That should give you something to start with. Hope this helps,
