This recently appeared as an option in Sellers Hub. Note highlighted part.
Clicking on the right tab brings you here.
The only 2 options still are promotions and sales event. Nowhere is there a place or way to send buyers coupons. Do they test this stuff before implementing? Something US sellers have had for several years. Even using dot com will show you send coupons but option is blocked as soon as system realizes you are a Canadian seller.
