From the Alzheimer Society of British Columbia: This guide is intended to provide basic tax tips that may be particularly useful for people affected by dementia. It is a summary, not a complete list, meant to alert you to options you may want to discuss with the person preparing your taxes.
For complete information about personal tax matters, contact the Canada Revenue Agency (CRA) by calling 1-800-959-8281 or visiting their website at alzbc.org/cra. Income tax rules are complicated and subject to change every year, so we encourage you to speak to a professional.
