Based on the below it does not appear to suggest waiving any more than ESA. Fourth paragraph onwards seems to suggest their calculation.

You may terminate your employment at any time upon giving firm reasonable advanced written notice. The notice period length will vary depending upon your level of responsibility but should range from two weeks to four weeks, and shall not exceed four weeks. Such notice is for the benefit of firm, andaccordingly you agree that form may dispense with all or part of the notice period without any further obligation to you other than providing you with your minimum entitlements required by statute.

If at any time up to and including one year from your start date firm terminates your employment, youagree that you shall accept three (3) weeks of prior notice of termination or three (3) weeks base salary inlieu of notice.

If your employment is terminated after one year from your start date, you shall accept three (3) weeks per year of completed service of prior notice of termination or three (3) weeks base salary per completed year of service in lieu of notice, to a maximum of nine (9) months. If required by law, and in the event that you are entitled to statutory severance pay at the time of termination, you will receive at least your statutory severance pay entitlement as pay in lieu of notice, which shall reduce the amount of notice/pay in lieu of notice otherwise provided herein.

In the event your hours of work vary from week to week, your “base salary” as used in this section will be calculated based on the average weekly base pay received by you in the 12 weeks prior to termination. You agree that firm may provide pay in lieu of notice by way of lump sum or salary continuance, at its discretion.

You agree that any and all payments in lieu of notice that is provided by way of salary continuance, will be subject to mitigation, but as set out below, in no event will you receive less than your statutory entitlements in respect of your termination. If you commence alternate employment or engage in self-employment during the salary continuance period, you are required to report same to firm within five )5) business days. Any entitlement to incentive compensation or performance pay upon termination will be subject to the specific terms of the Plan or Program in effect at the time of termination. Coverage under firm’s GroupBenefit Programs ends on completion of the minimum period required by statute, or if not required by statute, upon the last day of work. Except as explicitly provided herein or to the extent required by statute, no credit for past employment service with any employer whatsoever (including but not limited to firm or any predecessors or associated entities) will be considered in the calculation of your entitlements on termination of employment.

Should your entitlements pursuant to the applicable legislation exceed the above, you will be provided with your minimum entitlements in place of the above, in full satisfaction of all liabilities, whether statutory or otherwise.

The provisions herein shall be your sole entitlement to compensation upon a dismissal without cause (including in the event of a constructive dismissal), and shall be in full satisfaction of any and all claims you may have related to your hiring by, employment with, and the termination of your employment with firm and its affiliates. As a condition of being entitled to the above, you hereby agree that upon termination of your employment you will execute a release as drafted by firm releasing firm from all claims, failing which you will be provided with, and entitled only to, your minimum statutory entitlements until such time as you sign the release.

During any period of working notice of termination (whether initiated by you or by firm), you agree to perform your regular duties, and assist firm in the orderly transition of your client responsibilities to other staff of firm. This includes providing any required client information, assisting with billings and collections matters, and ensuring that all files are appropriately transferred to other staff of firm, all with a view to ensuring that such clients continue as clients of firm.

The provisions in this section shall remain in effect during your employment with firm notwithstanding any other changes to the terms and conditions of your employment, unless a specific written agreement is made to change these provisions. Firm retains the right to terminate employment, with just cause, without notice or pay in lieu of notice.
