Related to that, each Canadian province has the ability to further regulate marijuana (within guidelines). Thus, there isn't one Canadian market, but a bunch of smaller markets.
I know someone involved in the industry in Canada and they flew to Uruguay, the first country to legalise it, to learn from them and create connections. This role will be pioneered by Canada in many ways and it's much different than decriminalization.
There's tons of money to be made long term, not just within Canada but exporting knowledge and systems. I have a feeling this will be influencing many parliaments and congresses around the world to look into doing the same and other partner countries won't be far away.
It is a plant, a crop like any other. As a practical matter it is no more difficult than farming apples or corn. (It actually grows wild over much of Ontario.) The only specialized infrastructure is that dictated by regulation. Sure, Canada does have a jump on building out the regulatory infrastructure, but that isn't something we can sell. We aren't going to be exporting that infrastructure to other countries because they will have their own regulations demanding a different infrastructure.
As for supporting weed sales, there are "experts" on selling pot in every country in the world. That skillset is well understood. UBC will not see a wave of foreign students looking to lean the mysteries of how to sell weed. We aren't going to see Canadians flying around the world establishing new markets and trade links. This stuff is already being grown in closets from Dubai to Alaska.
Presumably, modern farmer techniques like indoor vertical farming might produce better yields.
Stems, leaves, and trim are probably just composted, although I suppose leaves might be processed to extract oils.
I recently visited Colorado on vacation, and got to visit a few legal dispensaries with my pothead companions (I'm not, but they are). It was a remarkable experience. Everything is totally focused on quality, and product differentiation for the marijuana itself was all about the best possible product with particular desirable characteristics. With few exceptions, price was a flat rate of $220/oz across the state. So maximizing yield is not nearly as important as maximizing quality. This is a connoisseur market. There was also a strong market for edible products (cookies, candies), oils, and other extracts.
It's also mostly an indoor crop. When I was in Oak Creek, a tiny town in the mountains, my host pointed out four different "grow room" buildings, basically urban farming operations.
It was interesting to talk about it with my host's fiance, a retired cop from Detroit (who is a part-time local cop there now). He thinks it's great, and marijuana laws in most states are just wasteful and stupid.

If anything will convince people that global warming is real, it will be wild pot plants surviving Minnesota winters.
That expertise has also been exported, to people trying to set up greenhouses in Minnesota (US).
As an aside, they also raise heirloom-variety turkeys. Minnesota is the #1 turkey state in the country, great area for it, and 99.9% of the turkey sold is a single breed. The heirloom breeds are rare (and delicious, and expensive) treats.
Metabolic engineering via genetic alteration has much more potential here since the types of oils produced can vary significantly, making the biotech aspects of growth more important than conventionally farmed produce.
The growth infrastructure will have to interface with the same plant and will have significant similarities regardless of the scale and accounting requirements you are limited to by regulation.
A street dealer who may, on a good day, have half a dozen random strains available may have a small head start, but there's a lot more to it than that.
Plus, our govt doesn't restrict sales to govt run stores.
California, Nevada, Oregon, Washington, Maryland all beat Canada to this. Hilarious that you seem to be oblivious to this.
BTW, California alone has a higher population than all of Canada.
B) Because cannabis is a controlled substance, Canadian companies will have no way to participate in local markets in other countries.
