Lien Deadline Calculator

Welcome to our Lien date calculator, or legal deadline calculator for filing liens in the provinces and territories in Canada.  Our filing date calculator provides the legal expiry date, or deadline for filing a lien. Find out the exact date deadline you have to file a lien with our Lien-Pro lien date calculator.

You can use our Lien Date Calculator to determine your lien filing deadline for  British Columbia, Alberta, Saskatchewan, Manitoba, Quebec, Nova Scotia, Newfoundland, Nunavut , Yukon, Northwest Territories and Ontario. Please keep in mind that this lien date calculator should only be used as a guide to determine the deadline when a Builders Lien or Ontario Construction Lien needs to be filed by. Avoid missing a lien filing deadline with our lien date calculator.
