That should be good hunting at that time most years.
Bring clothes for 50 degree highs to -20f + windchills though as that time of year you never know what mother nature will serve up. If using layout blinds, make sure you have snow covers with as you'll have a better than even chance of snow on the ground in the end on Oct. in SK over the course of a weeks hunting.
Make sure all people going are squared away - meaning no misdeanor convictions(simple assualt, DWI, DUI, etc..) in the US in last 10 years as US misd are considered felonies in CA when crossing the border and good luck if you ever had a domestic violence or US felony, as there is nothing worse than 1 in the group getting turned away from entering CA. Hard questions need to be asked of ALL in the party before the planning gets underway as to who all can go, so 1 person does not screw up the whole trip for everbody else.
