my cottage sits on a 12 deg slope, soil is in vertical layers sand, clay and limestone in
northern ontario, canada. Original foundation were piers, many at 18″ depth only.
Full block walls and infill walls between the piers (these at proper depth) replaced
the original structure. After heavy rain water filled the blocks and came through.
The contractors remedy was to dig a trench about 6″ deeper than the footings.
After heavy rain water cascades in a couple of places into the trench and later
seeps from the slope. This keeps the basement dry but is an eyesore.I want to divert
some of the cascading water and install a french conduit covered with sand and
rubble,the conduit connected to a culvert pipe about 40 ft long. One contractor
advises against it,another is for it. Any thoughts?

You have to have drainage. If you have the trench then get the fabric covered corrugated tubing and lay that in a gravel bed , covered with gravel. Then it should drain.
Couple of thoughts:
Can you landscape the above ground to divert the water flow?
How will the field (described above) of the building drain when the end freezes?
Why wasn't there a field installed with the foundation?
I'm planning on ending the culvert pipe in a gravel filled pit. Is there a better way?
Perhaps to daylight? To the street/storm drain? It depends on the situation with your property, nobody could really say without seeing it.

Open air is better if you can swing it. Just cover the end of the tile with hardware cloth to keep the animals out. The gravel pit would work fine If you were assured that the pit was always ready to take the drainage.Jack of all trades and master of none - you got a problem with that?
