To directly answer your question, different products have different requirements and are subject to different regulations. And each product and product category should be evaluated individually.

You can check the government link for some related info.

You can check the lab which issued the certification if they are authorized to issue Canadian certificate. You can also call the lab and make due diligence regarding the report. There are many other ways to verify the factory too.

I have been developing products for 15+ years and living in China for the last 10 years. I am happy to help with your further questions.

Cheers,
