This is an expat forum for expats based in Hong Kong so you're not going to find many Canada/HK tax specialists because the number of tax specialists in Hong Kong is very small to begin with as most taxes are very standard business tax/salary tax and specialists that deal with transfer pricing.
Better place would be to look at firms in Canada that can help. I used to be a Canadian tax accountant so I could refer some firms if you'd like and they could probably point you in the right direction.
