I would address this on the embryonic stem cell side.
Embryonic stem cell lines have been generated around the world, and some of them are imported into Canada. They have to be approved by the CIHR stem cell oversight committee, which reviews their derivation and the informed consent. They have to be approved under the same regulations as occur in Canada, and then they can be used.
It's very important, again, to be able to share expertise internationally and to share and cross-compare research across different jurisdictions.
