Ontario Command is divided into administrative areas called districts. There are nine districts, each assigned a letter, from A to K (excluding I and J). Districts vary in geographical size, number of branches and membership base.

Elected Commanders and Deputy Commanders, aided by councils which may have some elected members and some appointed members, assist Ontario Command in administering the large number of branches in the command. Each District has a representative on most Command Committees. The Commander of each District serves on the Provincial Administrative Committee, and along with the Deputy Commander(s) serves on the Provincial Executive Council.

Districts are further subdivided into zones. Zones are denoted by the district letter from the district they belong to, as well as a number (e.g. Zone G-4). Much like the districts, zones vary in geographical size, number of branches and membership base. The number of zones in each district also varies.

Zones also have elected commanders and deputies, as well as elected or appointed council members. Zones are represented at the Districts by the Zone Commander, who, along with the District Commander and Deputy Commander(s), is part of the Provincial Executive Council.

The most important element of Legion structure, other than individual members, is the branch. Each branch belongs to a zone, a district and a command. It is through this structure that branches are able communicate with, and receive direction from other levels of Legion. The branch is the most visible part of the Legion organization. Our local contact, it is through branches that most people experience Legion or benefit from one of its programs.
