Calgary document delivery date explorer
Pick the exact document first, because the rule is document-specific, then compare two service methods side by side. Alberta counts most periods in full tenancy periods or clear days; the explorer shows receipt and the date the document's own period ends. RTDRS filing deadlines are deliberately unsupported until mapped.
