Builder accessed my property to get to property beside me.

Hello;

The Alberta Land Surveyors Association is your best bet for an answer on this. They can be reached at http://www.alsa.ab.ca/.

In Ontario the builder would not be permitted to traverse or use your property unless there was a registered easement on title that permitted that use. New developments will often have time-limited easements across homeowner's lands that permit the builder to traverse so that they can move their equipment, materials and people in the most efficient manner to and from the sites they are working on. Usually these easements expire after a set number of years after the development is complete. To find out if such an easement exists you can contact your local Land Registry office or the Land Surveyor's association at the address above.

I hope this helps.
