India and Canada have appointed new high commissioners to each other's countries, in the latest step to restore ties strained by the killing of a Sikh separatist leader in a Vancouver suburb in 2023.

India's previous high commissioner left Canada last October after Ottawa expelled him, linking six diplomats to the murder of Hardeep Singh Nijjar - though Delhi insisted he was withdrawn.

That same day, India ordered out six senior Canadian diplomats, including the acting high commissioner.

The mutual expulsion of top diplomats last year marked an unprecedented low in an otherwise cordial relationship.

Nijjar, designated a terrorist by India in 2020, was shot dead by two gunmen outside a Sikh temple in Vancouver in June 2023.
