First, it is the national flag of the United Kingdom, and second, it is flown as a symbol of membership in the Commonwealth and allegiance to the Crown as approved by Parliament on December 18, 1964. The order of precedence of the Union Jack in relation to provincial and territorial flags varies in accordance with the reason it is flown. When the Union Jack is flown during a visit to Canada by a person representing the United Kingdom, the normal grouping of one Canadian flag and one Union Jack will be followed. On some occasions, it may be deemed necessary to add a provincial flag to the display. In this case the Union Jack will take precedence before the provincial flag as it represents the United Kingdom.
Physical arrangements means the existence of at least two flag poles.
The Canadian flag will always take precedence and will not be replaced by the Union Jack. Where only one pole exists, no steps shall be taken to erect an additional pole. The Union Jack may be flown with the Canadian flag at the National War Memorial and at similarly appropriate locations in Canada in connection with ceremonies marking anniversaries of events in which Canadian forces participated with other Commonwealth forces.
