Does B.C. Hydro's practice of unannounced meter readings constitute tresp?

How about unlawful search? I can't think of any other service provider, including the local constabulary, whose representatives are allowed to prowl the grounds of a residence at will without having to provide notice or identification. I also observe that after locating and reading the meter, these infections continue to wander the grounds peeking into windows and generally making a nuisance of themselves. Neighboring dogs go simply mad with ill will. Unfortunately, they are tethered and cannot have at 'em.
