See Overview

Tax planning and compliance
Whether you are a private or public organization, your goal is to manage the critical aspects of tax compliance, and achieve the most effective results. At Doane Grant Thornton, we focus on delivering relevant advice, and providing an integrated planning approach to help you fulfill compliance obligations.
Research and development and government incentives
Are you developing innovative processes or products, undertaking experimentation or solving technological problems? If so, you may qualify to claim SR&ED tax credits. This Canadian federal government initiative is designed to encourage and support innovation in Canada. Our R&D professionals are a highly-trained, diverse team of practitioners that are engineers, scientists and specialized accountants.
Indirect tax
Keeping track of changes and developments in GST/HST, Quebec sales tax and other provincial sales taxes across Canada, can be a full-time job. The consequences for failing to adequately manage your organization’s sales tax obligations can be significant - from assessments, to forgone recoveries and cash flow implications, to customer or reputational risk.
US corporate tax
The United States has a very complex and regulated tax environment, that may undergo significant changes. Cross-border tax issues could become even more challenging for Canadian businesses looking for growth and prosperity in the biggest economy in the world.
Cross-border personal tax
In an increasingly flexible world, moving across the border may be more viable for Canadians and Americans; however, relocating may also have complex tax implications.
International tax
While there is great opportunity for businesses looking to expand globally, organizations are under increasing tax scrutiny. Regardless of your company’s size and level of international involvement—whether you’re working abroad, investing, buying and selling, borrowing or manufacturing—doing business beyond Canada’s borders comes with its fair share of tax risks.
Transfer pricing
Transfer pricing is a complex area of corporate taxation that is concerned with the intra-group pricing of goods, services, intangibles, and financial instruments. Transfer pricing has become a critical governance issue for companies, tax authorities and policy makers, and represents a principal risk area for multinationals.
Succession & estate planning
Like many private business owners today, you’ve spent your career building and running your business successfully. Now you’re faced with deciding on a successor—a successor who may or may not want your direct involvement and share your vision.
Tax Reporting & Advisory
The financial and tax reporting obligations of public markets and global tax authorities take significant resources and investment to manage. This requires calculating global tax provision estimates under US GAAP, IFRS, and other frameworks, and reconciling this reporting with tax compliance obligations.

Helping LDCs better serve their communities

Cybersecurity of Local distribution companies (LDCs) is only as strong as the weakest link and a vulnerability on one local distribution company (LDC) could bring down the entire provincial network, causing untold damage to businesses, communities and the economy at large.

Digitalization initiatives and the expansion of remote workforces have transformed enterprises, causing once-isolated operational technology (OT) environments to become interconnected with their information technology (IT) counterparts. The result is the rise of converged IT/OT industrial networks with complex and expanded attack surfaces that IT security teams are increasingly responsible for protecting. The challenge is the OT portions of these industrial networks typically comprise proprietary protocols and unfamiliar assets, making them incompatible with IT security tools and invisible to IT security teams.

To help mitigate these risks, the firm has assembled an experienced team capable of delivering a specialized set of cybersecurity services geared specifically towards power utilities. Grant Thornton can provide utility-specific assessment services using frameworks such as NIST CSF, C2M2, NIST SP800-82R2 as well as benchmark against NERC CIP. We also provide tactical solutions such as the deployment of OT passive monitoring solutions allowing full visibility securely over a utility’s OT network.

Below are some offerings where we provide advisory services:

Cyber Assessment Solutions

T/OT Cybersecurity maturity assessments – utilities focused frameworks (i.e. C2M2, NIST CSF, ISO 27019, NISTIR 8259)
