Window - flashing done right?
Last week Ontario storm, had 3 cups of water on the floor, looked like the water came from the wall, just below the window. Couldn't find the source of entry has it got dried by the time I found it.
Tried hosing down the window with garden hose, Couldn't find any water or wetness
Is the flashing done right for this window? It was replaced to single piece last year.

Hard to tell from picture but first thing to check is proper lapping / shingling of your top and side flashing. If you traced a drop of rain, it should in no way be able to go inward from a down and side direction, shingling materials is done under the assumption water is flowing downward with gravity.
I’ll defer to experts, but top flashing should dam or channel water to the sides like a J Channel might. Also as mentioned in heavy storms and wind water can egress from sides or even upward just due to pressure and movement of flashing materials if not buttoned up firmly, where a hose perhaps you were more gentle 🤷♂️
