Knowing the location of your property boundary lines means you will know where to legally place features such as fences, pools, garages, or driveways.

Determining property lines in Ontario requires a combination of research, documentation, and sometimes professional assistance. Here’s a step-by-step approach to help you navigate this process effectively:

  1. Gather and Review Documentation

Begin by collecting all relevant documents related to your property. This may include your property deed, surveys, and land plans. These documents often contain essential information about the boundaries of your property.

  1. Study Your Property Deed

Your property deed is a legal document that provides a detailed description of your property’s boundaries. Look for terms like “metes and bounds” or “boundary description.” This section will outline the specific measurements and reference points that define your property’s dimensions.

  1. Engage a Professional Surveyor

For precise and accurate measurements, consider hiring a licensed land surveyor. Surveyors use advanced tools to map out your property boundaries with precision. Upon completion, they will provide you with a survey plan that includes clear demarcations of your property lines.

  1. Search for Physical Markers

Property boundaries are often marked by physical indicators such as stakes, pins, or monuments. These markers are usually placed at the corners of your property. Over time, these markers might have shifted or become obscured, so be prepared for some detective work.

  1. Utilize Online Mapping Tools

Various online tools and applications offer property boundary mapping using Geographic Information Systems (GIS). While these tools provide a general idea of boundaries, they may not be entirely accurate for legal purposes. However, they can be helpful as a starting point.

  1. Communicate with Neighbors

Your neighbors may have valuable insights into property lines, especially if they have conducted surveys or had boundary disputes in the past. Friendly conversations can provide additional information to cross-reference.

  1. Confirm with Local Authorities

Local municipal offices and land registry offices can provide historical records, surveys, and official documents related to property boundaries. This information can help validate your understanding of your property lines.

  1. Combine Multiple Sources

For the most accurate result, consider combining information from various sources, including your property deed, professional surveyor’s report, physical markers, and online resources. Cross-referencing these details enhances your confidence in identifying property lines.
