Welcome to Weiler & Company


WCO Chartered Professional Accountants formerly Weiler & Company

It is with great excitement that we announce a joining of forces between Weiler & Company and S&A Partners effective February 13, 2021.  Over the last few months, we have spent a lot of time with S&A Partners and we are impressed.  Our two firms have a similar client base and specialize in owner managed businesses as well as personal tax and cross-border taxation.  We are confident that this weill be good for our clients and for us moving into the future.

As part of our rebranding initiative, going forward we will be known as WCO.  Although the name and look are new, we will still be offering the same great service to our clients.  We are proud to provide accounting and assurance services, personal tax preparation, tax planning, cross-border tax service, estate planning and compliance, as well as consulting and advisory services.
