I want to ask you. My husband is Chinese in Canada. What materials do immigrants need?

If your husband lives in China, you have no reason to apply for immigration to Canada because of reunion;

So your husband must come back to Canada to live before he can apply for you, or he is ready to come back and live permanently.

Without a work permit, it is difficult to find a company to contact. But since you are in Shenzhen, he can go to Hong Kong to sign a tourist visa.

The materials are general materials, but you must make the immigration officer have no doubt about your marriage.
