Accessible Canada Act (ACA) Compliance

In Canada, legislation requires that videos and other media must be made viewable or audible for people with visual or hearing impairments.

What is ACA, and what standards need to be followed to ensure compliance?

The Accessible Canada Act (ACA) acknowledges and incorporates the WCAG guidelines as a recognised standard for media accessibility, emphasising the importance of making digital content accessible for people with disabilities.

WCAG is set around four principles: perceivable, operable, understandable, and robust. Sometimes communicated by the acronym POUR.

Perceivable: Text Alternatives

Provide text alternatives for any non-text content so that it can be changed into other forms that people need, such as large print, braille, speech, symbols, or simpler language.

Perceivable: Time-based Media

Provide alternatives for time-based media, such as audio and video. This includes providing captions for video content and text transcripts for audio content.

Operable: Keyboard Accessible

Make all functionality available from a keyboard. This is important for users who may have difficulty using a mouse, including some individuals with mobility impairments.

Operable: Enough Time

Provide users enough time to read and use content. This includes controls within media players to allow users to pause or stop, benefiting users with cognitive or attention-related disabilities.

Understandable: Readable

Make text content readable and understandable. While this guideline is broad, it can be applied to ensuring that text content associated with media is clear and easy to comprehend.

Robust: Compatible

Maximize compatibility with user agents, including assistive technologies. This involves using standard and well-supported formats for media content to ensure widespread accessibility.

What level of compliance is required?

Aim for WCAG level AA to be compliant with the ACA regulations. This ensures a baseline of accessibility for a wide range of users.

Provide text alternatives
for non-text content, such
as captions for videos and transcripts for audio.
Ensure keyboard accessibility
for media players, provide audio descriptions for videos, and sufficient contrast in text.
Provide sign language for live video content and ensure that captions are positioned in a way that does not obscure important visual information.
Ear icon


Many people who are Deaf can read text well. They get the audio information from transcripts or captions. Some people prefer sign language.

Eye icon


Some people who are hard of hearing like to listen to the audio to hear what they can, and have captions to fill in what they can’t hear adequately.

Brain icon


Some people who have difficulty processing auditory information also use captions. Many use transcripts so they can read at their own pace.

Speech icon


Some people cannot focus and comprehend auditory or visual information when there are changing visuals. For most videos, they also need descriptive transcripts.

How to make video and audio content compliant with ACA?

Integrate accessibility features based on WCAG level AA guidelines into your media content, digital products and services.

1. Level A accessibility features are included in your video

Upload a video file and automatically transcribe and subtitle your content in the language your audience speaks and understands.

2. Level AA accessibility features are included in your video

Include closed captions (CC) and audio descriptions in the Subly editor. Check your file for colour contrasts and include content warnings.

3. Video player supports AA accessibility features

Ensure that the video player supports level A and AA accessibility features, includes accessible controls, and can be navigated via keyboard.


Provide captions for pre-recorded audio content. Captions should be synchronised with the media and include all relevant information. This is particularly important for individuals who are deaf or hard of hearing.

Audio descriptions

For video content, provide audio descriptions of visual information that is essential for understanding the content. This benefits users who are blind or visually impaired.

Descriptive transcripts

Provide a text transcript for all pre-recorded audio content. This allows users who cannot hear the audio to access the information through text.

Sign language

For prerecorded video and audio content, provide sign language interpretation to make the information accessible to users who rely on sign language.

Adaptable content

Ensure that the media player can be operated using a keyboard, as some users may have difficulty using a mouse. This helps meet the needs of users with mobility impairments.

Keyboard access

Ensure that all functionality of the media player is operable via a keyboard interface, allowing users who cannot use a mouse to control and access the media.

Focus visible

Ensure that there is a visible focus indicator that can be seen and operated by keyboard users. This helps users with visual or motor disabilities understand where they are in the media player interface.

Accessible player controls

Provide controls for users to pause, stop, or hide any moving, blinking, scrolling, or auto-updating content within the media player. This helps users with cognitive or attention-related disabilities.

Flashing content

Content cannot have more than 3 flashes per second unless the flashing content is small enough, the flashes are low contrast, and they do not violate the general flash threshold.

Colour contrast

Small text (below 18 pt regular or 14 pt bold font) must have a minimum of 4.5 to 1 contrast ratio with the background. Large text (over 18 pt or 14 pt bold) must have at least a 3:1 contrast ratio with the background.

Media accessibility compliance lawsuits

What happens if I am not compliant?

Failing to comply with the Accessible Canada Act, can result in fines up to $250,000 and reputational damage.

Non-compliance may also result in civil lawsuits from individuals or advocacy groups, accusing your organisation of discriminating against people with disabilities.

These actions not only have financial consequences but also hinder the progress towards equal opportunities and the fuller inclusion of individuals with disabilities in society.

What is the difference between ACA and WCAG?

The Accessible Canada Act (ACA) is the legislation that enforces digital accessibility whilst WCAG are a set of guidelines that explain how to reach media compliance e.g. Audio descriptions, captions, etc.

Do I need to be compliant with the ACA?

All companies that are based and/or distribute digital recordings inside Canada should be compliant with the ACA regulations.

What if I am not compliant?

Failure to comply with the Accessible Canada Act can lead to financial penalties of up to $250,000.

Is having subtitles enough for ACA compliance?

Subtitles alone are not enough to meet media compliance. You need to have colour contrast checks, trigger warnings, audio descriptions, non-verbal captions, speaker recognition and more.
