Alternative and augmentative communication (AAC) systems enable interaction by persons with speech impairments, yet access to these devices is limited. In 2019, the Government of Canada introduced "The Accessible Canada Act" to reduce barriers. Availability of information online about AAC systems can reduce barriers to many Canadians who have difficulty attending in-person appointments. While Ontario's Assistive Device Program has been reviewed, other government-funded and charitable organizations across Canada have not been assessed for readability and accessibility. This research aims to evaluate the websites of organizations across Canada that provide AAC technology access, either through equipment loans or financial assistance programs. Forty-three eligible organizations were identified. Web Content Accessibility Guidelines scores (A, AA, and AAA) and four readability scores (Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, Gunning Fog, and age range) for each website were determined. Thirteen of 43 sites scored below the recommended standard of 75 for WCAG score, and Flesch Kincaid Reading Ease score indicated 86% were more difficult to read than standard recommendations for web content. To enhance equity in AAC device access, online availability of information and forms of government programs and charitable organizations must be easily understood and barrier-free.

替代和辅助交流（AAC）系统使有语言障碍的人能够进行互动，但这些设备的获取受到限制。2019年，加拿大政府推出了《无障碍加拿大法》，以减少障碍。在线提供关于AAC系统的相关信息可以降低许多因难以参加面对面预约而面临困难的加拿大人的障碍。虽然安大略省的辅助设备计划已经接受审查，但加拿大其他由政府资助和慈善组织提供的网站尚未评估其可读性和易访问性。本研究旨在评估为AAC技术提供获取渠道的全加范围内43个组织的网站（通过设备租赁或财务援助计划）。确定了每家网站的Web内容无障碍指南（WCAG）评分（A、AA 和 AAA），以及四个可读性得分（Flesch Kincaid 阅读舒适度、Flesch Kincaid 年级水平、Gunning Fog 和年龄范围）。在43个站点中，有13个网站的 WCAG 评分为75分以下，并且 Flesch Kincaid 阅读舒适度得分表明86% 的内容比网络内容的标准推荐更难阅读。为了增强AAC设备获取的公平性，在线提供的政府项目和慈善组织的信息和表格必须易于理解并且无障碍。
