Short answer: no — the mere fact that a court ultimately places the boundary somewhere other than the surveyor did does not, by itself, establish negligence. Negligence and being wrong are two different things, and the law is careful to keep them apart. To succeed in a negligence action a plaintiff must prove all of (i) a duty of care, (ii) a breach of the applicable standard of care, (iii) causation, and (iv) recoverable damage. Only the second element is engaged by the question, and it is not measured by the correctness of the result but by the quality of the professional's conduct.

The standard of care owed by a cadastral surveyor is that of the reasonably competent surveyor exercising ordinary skill, care and diligence in the circumstances then prevailing — judged by what was known and knowable at the time of the survey, not with the hindsight of the court's later ruling. This is the professional-negligence standard applied across the learned professions in Canadian common law (the Bolam-type test as received and refined in cases such as Lapointe v. Hôpital Le Gardeur, 1992 SCC, which holds that a professional is not negligent merely because a court, or another expert, would have reached a different conclusion, provided the professional acted in accordance with a reasonable and defensible body of practice). A surveyor is not a guarantor or insurer of the outcome; he or she undertakes to bring reasonable skill and judgment to the task, not to be infallible.

Boundary retracement is inherently a matter of opinion evidence. The surveyor's role is quasi-investigative: to gather and weigh the best available evidence of the original boundary in the accepted order of priority — natural boundaries and senior rights, then original monuments (or their proven positions), then the calls and lines of the original survey and conveyance, then measurements, and finally area. Reasonable, diligent surveyors can and do form differing but honestly-held opinions from ambiguous or conflicting evidence. When a dispute reaches court, the court is the ultimate finder of the true boundary as a matter of law; it may hear evidence the surveyor never had, resolve a genuine conflict of evidence, or apply a legal doctrine (adverse possession, estoppel, the seniority of an adjoining grant, or a conventional-line agreement) that changes the answer. That a tribunal armed with fuller evidence and legal authority reaches a different location does not retroactively brand the surveyor's earlier opinion careless.

Negligence would be made out only where the surveyor fell below the standard of care — for example by failing to search the registry or original plan, ignoring or failing to look for an existing original monument, misapplying the hierarchy of evidence, blundering the fieldwork, or reaching a conclusion no reasonable surveyor could support. In short, a defensible opinion honestly formed after competent research and a proper evaluation of the evidence is not negligent simply because the court, on the whole of the evidence, later disagrees. The question to ask is not "was the surveyor right?" but "did the surveyor do what a reasonably competent surveyor would have done?"
