I have tried both Centred AND Left & do not have the Widget weather icon; even with the default taskbar, which I don't use, normally.
Now of interest... on page 5 I showed the Time & Date window was ok & normal... I just checked it again and lo & behold; it no longer is... I will report this to FH.
The same happened to me, it is the update of the English (United States) Local Experience Pack that causes the problem, the same happens for other languages all over the world.
You can check the Version level that was updated on your machine.
On mine I can eliminate the bug if I remove the English (United States) Local Experience Pack which in my case is 22535.1.1.0, or if I put back the previous Version 22534.1.1.0.
Not sure if you have a different pack for Canada, just check what was updated from the MS Store.
