We present a new class of canonical labellings, \textit{hierarchical canonical
labelling}, for graphs in which if the vertices of a graph $G$ are canonically
labelled by $\{1, \dots, n\}$, then $G\setminus\{n\}$ is also canonically
We provide examples of such canonical labellings. As an application of these
labellings, we introduce a new method of generation based on this labelling that
combines the benefits of two well-known methods of generation: Orderly
Generation and Generation by Canonical Construction Path.
