We have been waiting for nearly a year now for Google Assistant to come to Chromebooks. It should be arriving in the coming week alongside Chrome OS 77 update. There are caveats, though. One is it'll be available in 15 countries. Another is that G Suite accounts won't have access to the feature yet. Developers are working on the best way for enterprise users to control access to Google Assistant.
As we mentioned, there are a limited number of countries the feature will roll out initially. There's also a limitation which chosen languages it'll be available in. For Canada, English and French will be supported. The other countries getting support for Google Assistant include Australia, Denmark, El Salvador, France, Germany, Italy, Japan, Mexico, Netherlands (Dutch), New Zealand, Norway (Nynorsk & Bokmål), Spain, the United Kingdom, and the United States.
