Canada's legal agreement with US is that they work in accordance with US, for criminals that violated the laws at Canada. But there needs to be laws in Canada that are equivalent to US ones.
For example, if I committed murder in US, and fled to Canada, they legally are obliged to capture and send me back to US. But if I sell limited item to Iran, and fled to Canada, then Canada are obliged to send me back, because Canada does not have a sanction on Iran.
And this is why this action outraged a lot of Chinese, and worried a lot business people.
