Why are people downvoting you? Iced tea in Canada is sweet. Think things like Brisk or Nestea. If you order iced tea at a restaurant here, it's coming out if the same machine as the pop (syrup+water) just not carbonated.
If you order an iced tea in Canada you are getting Nestea/Brisk like 95% of the time. Both are sweet teas, but are marketed and labelled as "Iced Tea", not "Sweet Tea" - ask our American beverage overlords Coke/Pepsi why
If you are in a cafe, or some other place where the expectation is that they brew their own, then yes, it's generally unsweetened - but it's also usually explicitly labelled as such on the menu so you know whether you are getting brewed tea vs a glass of corn syrup
Yeah it’s more of a semi sweet tea. Sweet tea is a syrup. Like, literally most home recipes I’ve heard call to add sugar until it stops absorbing while hot
