You got no information about Chinese supply chains, even transparency of stock listed companies in China are almost zero. China is heavily working against transparency standards in supply chains.
China is highly unreliable. Just look at China's Belt and Road Initiative 'partners' and how they do (or look at those who decided to leave the initiative).
There is ample evidence. I also sure you want the best for Canada but like everyone else has been heavily influenced by Chinese propaganda to dismiss China critics absurdly accusing them of being a racist.
