Tiling over vinyl floor

I am planning to install ceramic tiles on my kitchen floor. Current floor is vinyl. My contractor suggested that I don't need to remove the existing vinyl sheet, rather he would nail thin ply wood sheets on top of the existing vinyl floor and then install ceramic tiles.

My questions:
1. Is there any problem, if I leave the old vinyl sheets underneath the tile floor
2. What precaution I should take if I decide to leave the vinyl sheets under

Thanks in advance for your answer.

It's obvious you're talking to the wrong contractor, or is he a handyman? He has no clue.

Find a tile contractor and then let us know what he proposes, there's several ways to go.

And the several ways to do this doesn't include leaving the vinyl.

You should not leave the vinyl. For several reasons, the most important of which is you won't have a solid base for your new tile. Tile needs a rigid base, otherwise the floor will flex and that will lead to cracks in the grout joints and even the tile themselves.

Another reason is this will raise your floor level. Making it a problem for your entrances into other rooms. And also a problem for your appliances because the floor will then have a 'lip' in front of them. This sometimes makes it very difficult to get them out for service or replacement. You can't run the flooring under them because then they'd be higher than the existing cabinetry.

Pull up all the old flooring. In doing so you'll also be able to confirm that the subfloor is in good condition.

On a side note, have you confirmed that your floor joist structure is capable of supporting the weight of tile? It's called deflection and unless your joists are correct that too can cause tile to crack (even without the old floor still being there).

Any thin plywood is never a suitable underlayment for any tile.
Is the vinyl installed over 1/4 now? If so it needs to go also.
Going to need to know what size, spans and spacing your floor joist are and what's there now for subflooring and underlayment to make any real suggestions on how to proceed.
I for sure would let that "contractor" have anything to do with the floor if that's his idea of a suggestion!
