So 5 years later this wasn't answered I see.
Looks like you have to do "trades" evaluations via the province you want to apply to for PN or Express Entry.
As for education that is still good with WES.
As for "work assessment", no idea. I've been searching all day and contacting people. No one knows. There has to be someone if a Province requires it. The province should also list options of who to go to for the "work" requirement, if they are asking for it. Why so elusive?
