Canada

Research conducted in November 2025

Canada has a universal, government-funded healthcare system and has implemented a national dementia strategy to guide its approach to the condition. While the country has a strong research community and specialised care facilities, patients often face long waiting times for diagnosis. Some cultural and legal barriers persist that hinder access to support and care.

Overall
AD Rating
Diagnostic Pathway
Although there is a formal diagnostic pathway supported by guidelines, it is heavily bottlenecked, with long wait times.
Specialized Care
Canada offers a universal healthcare system and specialised memory clinics, but patients still face significant out-of-pocket costs and are waiting on regulatory approval for new disease-modifying therapies.
Caregiver Support
Support primarily relies on the non-profit sector and unpaid family labor, with state assistance limited to indirect financial relief such as non-refundable tax credits rather than direct cash allowances.
National Policies
Canada has established a multi-year national dementia strategy with clear objectives, guiding principles, and a legal requirement for annual progress reporting.
Access to ATT-s
Single therapy approved; no reimbursement.

Diagnosis

Canada’s dementia diagnosis follows a structured, stepwise approach recommended by the 2019 CCCDTD, beginning with a detailed clinical assessment and input from an informant, complemented by cognitive and functional evaluations. MRI is standard for detecting atrophy or strokes, with CT as an alternative. FDG-PET and CSF biomarkers may clarify atypical or early-onset cases. Cognitive screening uses tools like MIS, Mini-Cog, AD8, MoCA 4, and GPCOG, followed by comprehensive tests if positive. Genetic testing is reserved for young-onset familial cases. Long waits, up to 28 months, stem from limited specialists and imaging resources. Patients face average out-of-pocket costs of $1,360 yearly.

Diagnosis pathway

In Canada, the 2019 Canadian Consensus Conference on the Diagnosis and Treatment of Dementia (CCCDTD) recommends a thorough, stepwise approach to dementia diagnosis. The process begins with a detailed clinical assessment, incorporating both the patient’s history and input from a reliable informant, alongside a physical exam and evaluation of cognitive and functional abilities. Brain imaging with MRI is standard to detect strokes or patterns of atrophy linked to Alzheimer’s disease, while CT serves as an alternative when MRI is unavailable. In atypical or unclear cases, FDG-PET can improve diagnostic certainty, and CSF analysis may be considered for early-onset patients under 65 to clarify Alzheimer’s disease pathology.

The fifth Canadian Consensus Conferences on the Diagnosis and Treatment of Dementia (CCCDTD), that took place in 2019, outlined recommendations on the treatment and diagnosis of dementia. The diagnostic process starts with a comprehensive clinical assessment that includes taking a detailed history from the patient and a reliable informant, conducting a physical exam and assessing the patient’s cognitive and functional status.

A Magnetic Resonance Imaging (MRI) of the brain is recommended as part of the standard diagnostic process to look for evidence of other conditions like strokes and to identify patterns of atrophy associated with Alzheimer’s disease. A Computed Tomography (CT) scan is a suitable alternative if MRI is unavailable.

Fluorodeoxyglucose Positron Emission Tomography (FDG-PET) scans, which measure brain metabolism, can be useful for increasing diagnostic certainty in cases where the clinical presentation is atypical or unclear.

Cerebrospinal fluid (CSF) analysis is not recommended routinely, but it can be considered in dementia patients with diagnostic uncertainty and onset at an early age (<65 years old) to rule out Alzheimer's disease pathophysiology.

Wait times

Long wait time (expected)

Dementia diagnosis in Canada can face long delays, with waits reaching up to 28 months due to limited dementia specialists and imaging resources relative to high patient demand.

The waiting times for a dementia diagnosis in Canada are considerable, which is attributed to a high number of family physicians, but low number of dementia specialists and imaging equipment per capita. For example, according to one report, the waiting times for a dementia diagnosis can extend up to 28 months.

Diagnosis cost

Partially covered

Beyond publicly funded dementia services, Canadian patients incur out-of-pocket costs averaging $1,360 annually for medications, care, or home-related expenses.

In addition to the government funded services, such as medical costs of diagnosing dementia, patients also have out-of-pocket expenses, whether for additional medication or care, or other household expenditures such as renovations. The average out-of-pocket expenses are estimated at $1,360 per year.

Cognitive tests

Available

Cognitive function assessment is achieved by using rapid psychometric screening tools such as the Memory Impairment Screen (MIS), clock drawing test (CDT), the Mini-Cog, the AD8, the four item version of the MoCA (Clock-drawing, Tap-at-letter-A, Orientation, and Delayed-recall), and the general practitioner (GP) Assessment of Cognition (GPCOG). If the initial screening is positive, it is advised to use a more comprehensive psychometric screening tool (the Modified Mini-Mental State [3MS] examination, the Mini-Mental State Examination [MMSE], or the Rowland Universal dementia assessment scale [RUDAS])

Imaging tests

Used in specific cases

Anatomical neuroimaging is recommended in most situations; MRI is recommended over CT. FDG-PET scan is recommended for patients with a diagnosis of a cognitive impairment, but whose underlying pathological process is still unclear. If those patients cannot be practically referred for a FDG-PET scan, the recommendation is that a SPECT rCBF study be performed for differential diagnosis purposes. It is recommended that ordering PET amyloid imaging tests should be limited to dementia experts, and that an FDG-PET scan should be done prior to amyloid imaging.

Genetic tests

Genetic testing is only an option for families with young-onset familial Alzheimer’s disease, while genetic testing for sporadic Alzheimer’s disease is not recommended. Prior to genetic testing, one is to contact their primary healthcare provider and/or genetic counsellor. Private testing options are also available.

Biomarker tests

Used in specific cases

CSF analysis is not recommended routinely, but it can be considered in people living with dementia with diagnostic uncertainty and onset at an early age (<65 years old) to rule out Alzheimer's disease pathophysiology. CSF analysis can also be considered in people living with dementia with diagnostic uncertainty and predominance of language, visuospatial, dysexecutive, or behavioural features to rule out Alzheimer's disease pathophysiology. CSF and PET biomarkers are especially useful in complex or atypical presentations and early-onset cases, improving diagnostic accuracy and management; routine use in general practice is limited by accessibility, invasiveness, and cost.

Treatment cost

People with dementia face average out-of-pocket expenses of $3,700 annually, with costs over five times higher than for those without dementia. Long-term and home care drive expenses, while 350,000 care partners provide 470 million unpaid hours annually, valued at over $7.3 billion.

In addition to the government funded services, people living with dementia also have out-of-pocket expenses, whether for additional medication or care, or other household expenditures such as renovations. The average out-of-pocket expenses are estimated at $3,700 per year. Costs for those living with dementia are estimated to be five and one-half times greater than for those who are dementia-free. Long-term care and home care are the largest contributors to direct costs. A study found that in 2020 there were 350,000 care partners for people living with dementia. With an average of 26 hours of care per week, together this amounts to 470 million hours of care in a year. This number translates to a worth greater than $7.3 billion dollars for unpaid care.

Caregiver support

The Alzheimer Society of Canada provides in-person and online caregiver support groups offering information and peer guidance. Additionally, caregivers can access the non-refundable Canada Caregiver Credit for supporting partners with physical or mental impairments.

Alzheimer Society of Canada offers support groups, in-person and online, for caregivers. Support groups are based on an Information and Mutual Aid model, which means that caregivers can expect to benefit from reliable information provided by Alzheimer Society staff, and from the wisdom and experience of other group members who are also facing the illness. Canada caregiver credit – non-refundable tax credit that is available to those who support spouses or common-law partners with a physical or mental impairment.

Policy

Canada’s first national dementia strategy, Together We Aspire (2019), aims to prevent dementia, advance therapies, and enhance quality of life, guided by principles of inclusivity, human rights, evidence, and results. Provincial initiatives in Ontario and New Brunswick are developing frameworks and funding to improve care. Persistent gaps include cultural barriers limiting BIPOC communities’ access to support and legal challenges where families rely on court-appointed guardianships, highlighting the need for less restrictive alternatives like supported decision-making and personal directives.

National dementia plan

In 2019, Canada adopted its first national dementia strategy, Together We Aspire, following the 2017 Alzheimer’s Disease and Other Dementias Act and a 2016 Senate report. The strategy seeks to prevent dementia, advance therapies, and improve quality of life for people with dementia and their caregivers. Guided by five principles including quality of life, inclusivity, human rights, evidence-informed decision-making, and results-focused tracking, it rests on five pillars: collaboration, research and innovation, data and surveillance, culturally appropriate information, and a skilled workforce, with annual progress reporting by the government.

Canada’s first national dementia strategy “Together we aspire” was adopted in 2019; the strategy was a result of The National Strategy for Alzheimer’s Disease and Other Dementias Act (the Act) was passed in June 2017 and followed a comprehensive report on dementia from the Senate in 2016. This Act requires the federal Minister of Health to develop a national dementia strategy, host a national conference and establish a Ministerial Advisory Board on Dementia.

The national strategy is built on three key components:
1. Three National Objectives:
● Prevent dementia.
● Advance therapies and find a cure.
● Improve the quality of life for people living with dementia and their caregivers.
2. Five Guiding Principles:
● Prioritize the quality of life.
● Respect and value diversity and inclusivity.
● Uphold the human rights, autonomy, and dignity of individuals.
● Use evidence-informed decision-making.
● Maintain a results-focused approach to track progress.
3. Five Foundational Pillars for Implementation:
● Collaboration among all partners.
● Research and innovation to find therapies and a cure.
● Surveillance and data to understand the scope of dementia in Canada.
● Information resources that are culturally appropriate.
● A skilled workforce for research and care.

The strategy places special emphasis on groups at higher risk or those who face barriers to care, including Indigenous peoples, women, older adults, and individuals with other health issues. The government is bound to report annually on the strategy’s progress.

Upcoming plans

In December 2024, Ontario passed the Improving Care in Ontario Act, mandating a provincial framework to enhance dementia care. Likewise, New Brunswick committed $2 million to develop a dementia strategy, setting priorities and funding to improve care and quality of life.

In December 2024, the Improving Care in Ontario Act received royal assent. This Act directs the Minister of Health to develop a provincial framework designed to support improved access to dementia care. This direction includes the requirement that a future framework “takes into consideration existing dementia care frameworks, strategies and best practices” and “leverages the expertise and capacities of key partners in Ontario’s health system”. Similarly, The New Brunswick government announced plans to invest $2 million in developing a provincial dementia strategy. In developing a comprehensive plan, the New Brunswick government will be tasked with identifying priorities and allocating funds to improve dementia care and quality of life across the province.

Policy gaps

Legal barriers

When dementia impairs decision-making, families often face lengthy, costly court appointed guardianships that remove autonomy. Legally recognised alternatives such as supported decision making, powers of attorney, or personal directives, could let people retain control with guidance rather than lose their rights.

When a person living with dementia becomes incapable of managing their affairs without having planned, the only option is often a court-imposed guardianship, an intrusive process that removes their decision-making rights. The current legal system lacks sufficient alternatives. Without advanced tools in place, families often must seek court‑appointed guardianship/trusteeship, an intrusive process that can remove decision‑making rights and is lengthy, costly, and stressful. What’s lacking are accessible, less‑restrictive options that preserve autonomy and cover routine decisions – like supported decision‑making, enduring/continuing powers of attorney for property, and personal directives or representation agreements for health and personal care – so the court is not the only path. Adopting legally recognised supported decision‑making frameworks would help people living with dementia exercise their legal capacity with assistance rather than losing their rights.

Cultural barriers

In Canada, cultural barriers limit dementia support access for BIPOC communities. Stigma, language differences, and scarce culturally appropriate resources hinder engagement, while some Indigenous perspectives favor community-based care over formal systems to preserve elders’ roles and intergenerational knowledge.

Significant cultural barriers are present in Canada that prevent people in BIPOC (Black, Indigenous, and People of Colour) communities from accessing dementia support and participating in research. Factors such as stigma, language barriers, and a lack of culturally appropriate resources create obstacles for individuals seeking help from doctors or community organizations. A synthesis of qualitative evidence indicates that some Indigenous cultural understandings of dementia in Canada differ from a Western biomedical model. Consequently, informal and community-based models of care are often preferred – not because dementia is simply seen as a normal life stage, but because formal institutional caregiving is frequently viewed as disruptive to intergenerational knowledge transmission and undermining of elders’ roles in community life.

Research

Canada is leveraging cutting-edge innovations to prevent and treat dementia. Cognitive tools like HippoCamera enhance memory retention and hippocampal activity, while focused ultrasound offers non-invasive, image-guided targeting for Alzheimer’s disease, Parkinson’s disease, depression, and other neurological conditions. Concurrently, the CAN-THUMBS UP (CTU) consortium of over 100 researchers promotes dementia risk reduction through its Brain Health PRO (BHPro) program – a 45-week, bilingual online platform combining multimedia modules, quizzes, and interactive exercises to encourage positive lifestyle changes, empower participants, and translate research insights into practical prevention strategies nationwide. These initiatives exemplify Canada’s integration of neuroscience, technology, and public engagement in dementia care.
