What you are looking for is most commonly referred to as a "3.5mm camcorder AV cable". I couldn't find one listed at Future Shop. Try looking in a shop that specializes in selling cameras and camcorders. Alternatively, you can easily find one elsewhere online by searching on the term I provided above.
I am surprised you have a VCR with such an output jack. Typically these jacks are found on small camcorders.
