Does delivery from Amazon.com to Canada depend on what the third party seller allows? I thought they shipped to Canada for a little extra?

The ZW36 is just the Jasco plug in disguise so if you can get any of the Jasco Zwave plugs they will also work with wink and any other hub. Leviton does have an appliance plug that can handle higher loads but the reliability isn’t the best comparatively (the lamp ones work well though).

This dual outlet plug also works, if you can get it.
