Do All Arbitration Clauses in Employment Agreements Violate the ESA?

In Rhinehart v Legend 3D Canada ( 2019 ONSC 3296) Justice Sanfilippo was faced with a motion by the defendants to stay the action as the employment contract had an arbitration clause that said as follows:

All of us at Legend are very excited about you re-joining our team and look forward to a beneficial and fruitful relationship. However, should any dispute arise with respect to your employment or the termination of that employment, we both agree that such dispute shall be conclusively resolved by final, binding and confidential arbitration in accordance with the Voluntary Labor Arbitration Rules of the American Arbitration Association (AAA) in San Diego, rather than by a jury, court or administrative agency.”

This agreement was signed by the Plaintiff when he worked in California for the US parent. He then moved to Ontario and employed by the Canadian subsidiary, but he never signed an agreement with the Canadian company.
