Presumably at some point after Wyze actually starts selling its products in other countries. Right now, sales and support is limited to the US, so it’s not recommended that international users buy the products. If you have warranty issues, for example, they can’t send you replacements, and some of the features (such as the Alexa skill, 2FA, and probably some others) are limited to the US. Some of those may work in Canada too, but I’m not sure.
I know that full Canada support is their next international priority. I’m not aware of their expansion plans beyond that. Hopefully they will at some point in the future, but I know there some hurdles associated with that. (International regulations, support for multiple languages, shipping arrangements, localized server stacks, etc.)
