[Koha] Question about Amazon content

Hello Folks, I'm running Koha for a small collective of libraries and I'm considering turning on the Amazon content. Most of our users are likely to want to use Amazon.ca rather than Amazon.com and I'm wondering if anyone knows if we can use an Amazon.ca associate ID or does Koha only connect with amazon.com (therefore needing to use the amazon.com associate programme)? Thanks! Dwayne
