TC PICUS towards FAA ATP

[Mellowflight]

Does anyone know if I can use TC (Canadian) approved PICUS towards my FAA ATP PIC requirements?

Planning to call the FAA and clarify, thanks in advance.

Only time as defined & allowed in 14 CFR Part 61 can apply to a Part 61 licence. In effect, you will have to go through your log book and extract times that conform to the Part 61 requirements for an ATP. If those times meet the Pt61 minimum requirements for an ATP then you're fine.
