2.1 Civic Address Naming and Format To help avoid confusion, we suggest these naming guidelines for local addressing authorities to follow : • Every street should have one and only one name, • Street names should not be duplicated even though they have different street types (e.g., Pine Avenue as compared to Pine Street), • Similar sounding or spelling of street names should be avoided (e.g., Hands Road with Rands Road, or the spelling MacDonald Boulevard versus McDonald Boulevard). ese guidelines help with emergency services and with neighbouring municipali- ties, which can be any government regulated region (i.e., local, provincial or federal) adjacent to another similar region. ese guidelines also show the importance of coordinating street names between neighboring regions. For example, a munici- pality should avoid using the same street names for their local roads as those in a neighbouring municipality. Likewise for roads crossing municipal boundaries, the municipalities should use the same name and attributes along these continu- ous features (i.e., road names and civic address ranges). Such coordination should also occur with higher government jurisdictions (e.g., counties, regional districts or upper tier municipalities). 2.2 Address Format Addresses have several components, and the minimum components are address number, street name, street type, municipality, province and postal code. Addressing authorities should note that a postal code is not typically considered a minimum component of an address for NG9-1-1 purposes, as the postal code is assigned, not by local authorities, but by Canada Post to guide a letter to its eventual postal location. However, we include it in the schema shown in (1) for the purpose of completeness. erefore, the entire address format (i.e., data schema) includes these components in the following sequence: (1) Unit Number + Unit Number Suffix + Address Number Prefix + Address Number + Address Number Suffix + Modifier Prefix + Directional Prefix + Street Type Prefix + Street Name Pre-Type Separator + Street Name Body + Street Type Suffix + Directional Suffix + Modifier Suffix + Locality (Munici- pality) + Province + Postal Code. When addressing authorities supply GIS address data, each component in the schema must correspond to its unique data field. Furthermore, a complete address data field must include all the concatenated components in the above sequence. Community Civic Addressing Guide to Best Practices v4.0 2
