Our Canadian power and utility audit clients reach from coast to coast and beyond Canadian borders. Many of our clients are highly acquisitive, with operations that include renewable energy, transformative technologies and large-scale infrastructure development. With a 19% audit market share of the power and utilities companies listed in the 2015 Fortune Global 500, EY is one of the leading auditors serving the power and utilities sector globally.

Our clients benefit from the global network of 1,400 assurance professionals in EY’s Power & Utilities practice, who have deep experience in the sector’s key risks and specific regional and subsector issues.

Over the years, this experience has enabled us to develop customized guidance that can answer many of the questions your company may have about accounting issues.

Climate Change and Sustainability Services

In addition to the services above, we can assist with climate change governance.

We can develop carbon models and strategies to drive long-term optimization of your asset portfolio as we transition into a low-carbon market and provide carbon tax advisory services.

1 The Committee of Sponsoring Organizations of the Treadway Commission (COSO) updated and released its 2013 internal control framework that many organizations use to assess internal control over financial reporting to address changes in the business, operating and regulatory environment. The 2013 framework includes many enhancements and "points of focus" such as Principle 8 dealing with fraud risk assessments, which may lead organizations to challenge whether they need to enhance their processes to identify risks of financial statement fraud and design and implement controls that address those risks.
