I get the employee rate currency change too because my mom used to work there but yeah... Your parents have you a good deal! usually its about 106.75 aprox. for 100 dollars. But inless they got a good deal. I've always done all my currency exchanges at Scotiabank... so yeah...
Today if you went to the bank and asked for 500 it would be around 532.40 which is a rate of 1.0648
And you can do it yourself anytime with any currency from this site =D
