Stateless Passport transiting in HK

Good morning,

As a person who is holding a stateless passport from Brunei ( ICI passport), i am transiting in HK ( 1 hour - not exiting the airport, hence not going through immigration) to go to Vancouver, Canada, would I be required a visa?

Airlines we are using are Cathay Pacific (from KL to HK) then connecting to Air Canada ( HK to Vancouver).

Many thanks for your advice.
