What is an application under the Boundaries Act and when would I use one to fix an uncertain property line?

An application under the Boundaries Act is a formal process for conclusively establishing and confirming the true location of a property boundary that's become uncertain, lost, or disputed, for example, where original survey monuments have disappeared over time, legal descriptions from different eras don't quite line up, or neighbours simply disagree about where the actual line falls. It's a more formal and permanent route than a private handshake understanding between neighbours.

The process typically starts with an Ontario Land Surveyor investigating the historical evidence, such as old surveys, monuments, deeds, and physical features, and preparing a plan showing where the boundary should properly sit. That work ultimately goes to the Director of Titles for confirmation, resulting in a boundary that becomes fixed and binding on title, giving both current and future owners genuine certainty rather than relying on an informal understanding that a later buyer might not accept.

This route makes the most sense when the uncertainty is genuine and significant enough to matter for something like construction, financing, or a future sale, not for every trivial disagreement, and it's worth discussing with a lawyer and land surveyor whether a full Boundaries Act application, or a simpler private agreement, better fits your specific situation.
