Companies can offer a range of additional benefits here. Typically, employers will choose a salary percentage (between 15-75%) and number of weeks the top-up will last for. Usually, top-ups are above what the ESA offers so there may be additional requests from your employer. Make note of what documentations you’ll need to provide (e.g. proof of EI benefit from Service Canada) and enhanced notice to your manager. You’ll likely also need to communicate with your manager when you plan on beginning your leave and when you plan to return in advance so check your policy to ensure you’re providing enough notice.
