Is it OK to drill round holes in the flooring where house wiring
crosses the joists so that there is no pressure on the wires at
those points?

Between the joists the wires would be pushed slightly below the flooring.

Thank you for advice.

No it is not. Wires must be 2 inches below the top of the joist.-

IDK where that is coming from. You can't get 2" inside typical
interior 2x4 framed walls because the it's only 3 1/2 inches wide.


US NEC requires if edge of hole in stud/beam is 1-1/4" from edge, then
it needs must have the 1/16" T steel cover plate over the location for
protection. I'd suspect Canadian Code to be very close to same if not
identical.

Aither drill the joists or strap the floor with minimum 2 inch
strapping to space the floor above the wiring, which would then need
to be strapped to the joists.

In unfinished attics, open cable across top of must have guard strips of
minimum height height/thickness of cable and if running across top,
can _NOT_ be unsupported, _MUST_ be on a running board, not suspended.
This is allowed if thru bored holes 4-1/2ft or less span (how they got
that one, I don't know... ).

The flooring either side of a cutout could serve as the guard strip but
I'd suggest covering the openings. I _think_ once the floor is in place
the "no hanging" requirement is removed as it then is protected from
having anything pulling it down or from being stepped on, etc., ...
