I've noticed that tournament courses are often the original Links version when more recent (and better) APCD versions are available.
Also, the courses that are being used sometimes bear no relation to the tournament being played. For example, this past week the tour was in Mexico, while LSPN was using an old version of Biighorn.
There are 2 Real Mexican courses that are available and both have PGA yardage. (The Ocean Course ar Cabo del Sol and Chapultepec)
BTW, this tear's Canadian Open is at St. George's in Toronto. There will be a tournament edition released before the tournament begins.
