Sailor first class

As of August 2020, the Royal Canadian Navy replaced the term seaman with the gender-neutral term sailor. Leading seamen are now referred to as "sailor first class" (often abbreviated as "S1").^[1][2][3]

While the rank is used in a number of NATO countries, it is ranked differently depending on the country.
