Overview
Annually, designated industrial property owners will receive a Request for Information (RFI) from the provincial assessor. This is a requirement for property owners provide information on their properties by updating, adding, removing or otherwise correcting inventory details.
The package contains an RFI guide or reference and a pre-populated inventory showing current provincial database records.
The RFI indicates a deadline for the response. It is important to respond to this request in a timely manner as it may impact the eligibility of future complaints filed against the resulting assessment.
RFI response deadlines
| RFI type | Date of request | Response deadline |
|---|---|---|
| Land, buildings, structures, machinery, and equipment (industrial) | August of every year | October of every year |
| Major Cost Reporting properties, which include industrial major plants (MP) and linear electric power generation (EPG) facilities. This RFI is specific to major plants and EPG facilities | May of every year | August of every year |
| Linear (excluding Lin EPG Major Cost Reporting) | September of every year | November of every year |
