Fill a highball glass with ice.
Pour in the Canadian whisky.
Top with cold lemon-lime soda.
Stir once, gently, to combine without killing the carbonation.
Garnish with a lemon wedge.
The name is a brand joke: Seagram's Seven Crown and 7 Up. It dominated American bars from the 1970s through the 1990s and is worth knowing as the baseline every other whisky highball is measured against. A fresh lemon wedge, squeezed in, improves it more than a better whisky would.
