Canadian visa matters

Listening to your narration, I guess you have probably been deceived, because when applying for a Canadian visa, you do not need to mail the original passport to Canada. Nowadays, you can apply for a Canadian visa online, and you only need to bring your passport with a photo. Just scan the page to the Canadian visa website. So the agency is deceiving you when it says that your passport is in Canada, and it just doesn’t want to give you a refund. It seems that the agency either did not submit the Canadian visa to you at all, or submitted the Canadian visa to you, but the visa was rejected. The agent is just hiding it from you. It is difficult to apply for a Canadian work visa, and many Chinese people have been refused visas. You'd better check on the website of the Ministry of Commerce of China to see which agency has the qualifications to handle Canadian labor services. Finally, I object to you re-applying for a passport, because once you re-apply for a passport, the original passport will be invalid, which will have an impact on applying for a Canadian visa there. You'd better negotiate with the agency quickly to return the passport and refund the fees.
