The gap has closed for USA but the FR-S is still marginally cheaper... then you realize Subaru will go below MSRP and Scion has 'Pure Price'.
FR-S $26,075

BRZ $25,695 + $795 delivery fee = $26,490

(doing build your own will input the delivery fee)
Looking at the Canada Build your own BRZ website there is a $1,650 shipping fee and another $115 'other fee', the Scion website rolls taxes and fees in as well so it plops another $5k onto the $27k figure, too lazy to actually break it down.
BRZ may not be cheaper up there, you have to go through the whole process.
