Did the Royal Canadian Navy join China coast patrols?

Was the Royal Canadian Navy involved in these counter-piracy operations?

Not in a meaningful expeditionary role; the 1920s RCN was too small and focused largely on local fisheries protection.

Canada retained a naval organization, but it was extremely small during the 1920s. Its practical emphasis was closer to fisheries protection than long-range expeditionary operations. It lacked the force structure and overseas support needed to sustain China coast patrols. The answer therefore distinguishes a real but modest service from the larger British and regional forces active on the China Station. It also prevents Commonwealth participation from being treated as automatic or uniform.
