I have to apologize because I'm not a transportation expert here.
As far as I know, from experience during the discussions at APEC, Taiwan and Canada both have a very advanced single window service. Basically, there is no bureaucracy there. So far, from what I hear from our Vancouver office, the bottleneck is coming from domestic transportation in Canada, and I hope the problem can be solved.
If I find out any other information, I will let you know.
