Canada DCT routings
Hi all, I need to file a route from Labrador to the US midwest, and the high level airways structure isn't hugely efficient to get where I want to go. It makes sense for me to file a bunch of DCTs before picking up airways again on the last 25% of the flight, but I want to check Center(s) are happy with this - in particular that I'm not routing over a danger area or suchlike. So 2 Qs:
1. Does Canada allow long high level cross country DCTs like the US?
2. How could you check a route is ok beforehand? (I've seen the CFPS system but can't see a 'test route' facility).
