Now with five CPAs on staff – Big expertise meets personalized care.

Drawn to Collingwood over 20 years ago by the beauty of Georgian Bay, the proximity to Blue Mountain ski resort, and the small town charm, we established our accounting firm in the heart of Collingwood’s Historic Downtown. South Georgian Bay is a vibrant, growing, entrepreneurial community, and we are proud to support it. Over the years, C.E. McMahon Professional Corporation has grown substantially, expanding our Personal Tax Planning and Corporate Tax Services while building a team committed to providing friendly, approachable, and professional service. We proudly serve clients in Collingwood and the surrounding areas, helping them achieve their financial goals with confidence.

Whether you’re filing personal taxes, planning for retirement, or seeking corporate accounting expertise, C.E. McMahon Professional Corporation is here to provide tailored solutions and trusted guidance every step of the way.

We answer common tax questions such as:

TAX ADVICE FOR SENIORS

• We provide specialized tax guidance for seniors to help maximize your refund and minimize tax obligations. Our team focuses on areas unique to retirees, including:
• Pension income splitting
• Claiming medical expenses
• Caregiver or attendant care expenses
• Disability tax credit allocation
• Nursing home expenses

We ensure all eligible deductions, credits, and income sources are accurately reported, helping you optimize your tax return while staying fully compliant with CRA regulations. Our goal is to make the process easy, stress-free, and tailored to your financial situation.

ESTATE PLANNING

Part of retirement planning involves estate planning– making or updating your will, naming your estate representative, and considering funeral arrangements. Our team is here to help guide you through these important decisions– offering transparency and openness in our discussions with you.

C. Elaine McMahon CPA, CGA

With over 35 years of experience, I bring a unique perspective to accounting — one shaped by an accounting background in construction and robotics engineering before starting my own firm. This real-world business insight continues to guide my approach today: practical, strategic, and always client-focused.

I founded the firm with the goal of helping individuals and businesses build strong financial futures through tailored tax planning and strategic advice. My deep understanding of how businesses operate — across departments and industries — enables me to offer more than compliance; I provide meaningful solutions aligned with each client’s goals.

Known for being accessible and relationship-driven, I prioritize staying connected with clients throughout the year. This commitment extends to-our team, fostering a work culture centered on life/work balance, believing that a supported team delivers the best service.

Today, the firm serves a diverse client base across a wide range of industries, built on reputation, results, and long-standing trust.
