I was sent an interesting link to a Canadian Supreme Court decision from 2016 in regards to an employee being let go without cause under the Canada Labour Code (CLC). As you may know, most ship's crew in Canada fall under the CLC so this decision might be of interest to you.

You can read about it from these two blog posts. https://ravenlaw.com/blog/wilson-v-atom ... ost-wasnt/ and a little broader context from http://www.thecourt.ca/wilson-v-atomic- ... ismissals/
