First you would have to shut down the softwood lumber dispute from the USA. Then you'd have to start rebuilding the forestry infrastructure that was mostly bought out and moved to the USA decades ago... What's happening now is sustainable, where it's still happening - just a pale shadow of what used to happen. And then there's huge spaces that are entirely inaccessible (no roads, no flight access, and hostile weather). Not saying it's not doable, just that there are a lot of barriers.
(note : I just live here, but the forestry I remember being involved in everything - good and bad yes - as a child has been gone since the USA started vacuuming all the companies doing it up. So largely have the jobs gone, too).
