The CTC S15 Series Store Coupon is the first issue of the modern design replacing the older Sandy McTire's from the Store and also the Gas Bar series coupons.

This was also the first appearance of Hugh Macaulay's and Stan Pasternak's signature. Macaulay was Chairman of the Board from 1984 to 1994.

This series contains a small quantity of notes with compressed serial numbers inter dispersed throughout each denomination.

This redesigned coupon uses paper with red and fluorescent threads, a watermark pattern of CTC triangles, micro-printing and a latent image of a maple leaf.

Replacement coupons were issued with a 9 prefix in the serial number.
