Re: Water stain on basement drop ceiling next to exterior wall
I can see the middle picture fairly well but are having trouble putting the 1st and 3rd pics into perspective of what I am looking at.
Do you have a picture from a higher angle showing the junction of the wood siding and the brick?

Re: Water stain on basement drop ceiling next to exterior wall
What if the tile was not stained at that location?

Re: Water stain on basement drop ceiling next to exterior wall
Could it be by the masonry chimney which cold draft caused spot condensate? or previous leaking from chimney flashing

Re: Water stain on basement drop ceiling next to exterior wall
The transition from siding to veneer can certainly be a trouble spot. But you say the ceiling is leaking, isn't that below the ceiling?
With 1st and 3rd, post some far away photos, so I can visualize what I am looking at.
In a building that size, I agree that it is not condensation... unless there is a leaking condensation drain or some other unusual condition.

Re: Water stain on basement drop ceiling next to exterior wall
The dropped ceiling usually is added to cover up a bunch of unsightly ducts and plumbing pipes. The stains are usually from dripping plumbing pipes. Sometimes the copper cold pipe will sweat a bit, but more likely it was a leak, maybe a dripping drain pipe.
At sea level in Southern BC, brickwork against a wall doesn't get cold enough to cause condensation. Any moisture behind bricks will be due to rain leaking in.
