BPA in my breastpump

I found out today that my breastpump (Purely Yours by Ameda) contains BPA. In Canada, the company is giving out BPA-free replacement parts. I've been fishing around to see what's possible here, but so far nothing has come up. I think this is incredibly tacky on Ameda's part. Whatever happened to being concerned about customer safety and satisfaction? I mean, this is BREASTMILK we're talking about here! Surely that should be the safest thing I give my baby!
