The Sri Lankan high commissioner to Canada is the Sri Lankan envoy to Canada. Countries belonging to the Commonwealth of Nations typically exchange high commissioners, rather than ambassadors. Though there are a few technical differences (for instance, whereas ambassadors present their diplomatic credentials to the host country's head of state, high commissioners are accredited to the head of government), they are in practice one and the same office. Sri Lanka also maintains a consul-general in Toronto.
