where should I apply my Hong Kong passport in Edmoton Alberta?

If you go to HK soon, you should apply from the HK Immigration Department directly. Once it is done, you can get it back on your own. And of course you can apply from the Chinese consulate in Calgary. They just post your application to HK and then inform you of taking it back once it is sent to them. You still need to pay them CAD 65 as service charge.
