22(1)Substantial compliance with sections 20 and 21 is sufficient; and no lien is invalidated by failure to comply with any requirement of those sections unless in the opinion of the judge who tries the action, the owner, contractor, sub-contractor, mortgagee, or some other person is prejudiced thereby, and then only to the extent to which he is so prejudiced.

22(2)Nothing in this section dispenses with the requirement of filing a claim of lien.

22(3)Where, in the opinion of the judge, some person has been prejudiced by failure on the part of the lienholder or his agent to comply with one or more of the provisions of sections 20 and 21, the judge may allow such amendments to be made as are required to comply with those sections and to permit the action to be tried, without prejudice to any person.
