Summary
To find your property lines accurately and legally you will need a licensed Land Surveyor to do property research, take field measurements and confirm the boundary. There are some tools you can use to approximate the location of your boundary but these are not accurate enough to establish the legal boundary.

Find your property lines by using a licensed land surveyor.
GIS Data
You can get free property information from municipal and county GIS data that shows approximate property lines. This data is not accurate and may not align with ground conditions. It can be used for a rough approximation and a general idea of your property information. It cannot be used for establishing a legal boundary.
Public GIS Databases will show approximate properly lines:
City of Ottawa: GeoOttawa Database
United Counties of Leeds & Grenville: Public Map Viewer
Legal Survey
The only way to establish yourproperty lines accurately and legally is by contacting a licensed land surveyor. The surveyors will do research on the property, conduct field work and determine the boundary.
GIS data cannot be relied upon to establish a legal boundary as it is not accurate to the ground conditions. You may know where a property bar is, but not all property bars are at a corner or in the precise location. The only way to determine the exact property line is by having a surveyor establish the boundary by measuring each monument to adjacent monuments.
