(RMOC) and managed by the RMOC until 2001. In 2001, when all six cities, four townships, and one village within the former RMOC amalgamated to form the new city of Ottawa, responsibility of the regional road system was transferred to the new city of Ottawa, and they became today's “Ottawa roads”. In general, even-numbered routes run east-west and odd-numbered routes run north-south. Also, the lowest-numbered routes are generally found in the southern part of the city for even (east-west) numbered routes, and in the western part for odd (north-south) numbered routes. This pattern, however, has many exceptions. As more roads were added to the numbered-road system, the availability of numbers decreased and consequently, the numbering pattern had to be broken.

In smaller communities and rural areas the numbered roads are, for the most part, adequately signed with trapezoid-shaped signs with rounded corners, which are often referred to as "flowerpots" due to the shape of the sign. Older signs installed prior to 2001 have the legend "Ottawa-Carleton" at the top with the route number underneath. Newer signs installed after 2001 use the legend "Ottawa" or simply the "O" portion of the city's wordmark. Most numbered-road signs are not marked with directional tabs indicating the direction of the road (i.e. North, South, East, West), but where these appear, they are always printed in both English and French. Most numbered roads in the urban areas of Ottawa are not signed with route numbers, despite having official route numbers and being listed on many maps with these numbers. Instead, most urban sections of numbered roads are referred to by their names. Ottawa's city council adopted an updated route-numbering policy in 2005, under which road numbers are no longer posted inside the

, a former provincial highway, which is now usually known as "The 174". This effectively makes most Ottawa Roads within the greenbelt only used for internal purposes, as they are not signed. This is especially the case for Ottawa Roads 70, 78, 82, 105, and 113 which have little to no public record, due to the fact that they were likely numbered after numbering was discontinued in the downtown core.
