If one-way travel is booked, the full base fare will be charged, the voucher will be deemed fully used and the return portion of travel is forfeited.
This link is for the WestJet RBC Mastercard voucher T&C, but this outlines the different categories of Canda/Continental US or Sun destinations or Europe and also is the same guideline used when booking an Anywhere WestJet flies voucher.
Well, the Gold / Platinum companion vouchers do not state any of the rules above (and do not require paying a fare for the companion), except for the one-way restriction. Worth a try, then.
