"Factual causation" refers to the direct relationship between an action or event and its actual result. It means that a particular event or action was the direct cause of a certain outcome or consequence. In other words, it is establishing that if the action or event did not occur, the desired result would not have happened either.

I'm trying to gather anecdotal information as to whether the SCC decision in Resurfice v Hanke, 2007 SCC 7 and the «material contribution» doctrine mentioned in the case are helping plaintiffs get before - trial settlements — by using the Resurfice «material contribution» notion to get them past difficulties in proving
factual causation using the «but - for» test — which are settlements that they might not have been able to get before Resurfice.
Whatever factual causation actually means in the «real» world outside of the cloisters of law — take my word for it, the situation is worse than implied in either the English or French versions of para. 20 in Resurfice — it can be reasonably said that most judges and juries somehow got and get to the correct decision on what caused what.

So all of the cases decided between Athey in late 1996 and Resurfice in early 2007,
where factual causation was decided on an Athey material contribution basis, were decided as they were as the result of the provincial trial and appellate court judges» misunderstanding of Athey?

[126] The «but for» test is the general test
for factual causation: the plaintiff must prove on a balance of probabilities that but for the defendant's negligence, she would not have suffered her injuries.

[39] While he was likely also referring to the other part of the Snell mantra, which also quoted, that
