Select postalcodes.CityName, postalcodes.ProvinceAbbr
FROM postalcodes LEFT JOIN populations
ON postalcodes.CityName = populations.City AND postalcodes.ProvinceAbbr = populations.State
WHERE populations.City IS NULL AND populations.State IS NULL

You can also try this.
select *
  from postalcodes pc
 where not exists (select 1 
                     from populations p 
					where pc.CityName = p.CityName 
					  and pc.ProvinceAbbr  = p.ProvinceAbbr)
