One of the first questions chef Travis Petersen asks guests as they arrive to his supper club at a semi-secret Vancouver location is how they would gauge their cannabis tolerance. The 34-year-old former "MasterChef Canada" contestant will then dose the forthcoming multi-course dinner with the appropriate amount of cannabis-infused oil.

Eight diners sat around a large wooden table adorned with fall-themed centrepieces and joked about whether they're a one or 17 on a scale of 10 before falling silent as artfully plated dishes of geoduck, octopus and chorizo tacos, and butternut squash tortellini appeared before them -- which Petersen had topped off with an eye dropper of cannabis oil.

 In 72 hours it will be legal for adults in Canada to purchase, possess, or grow recreational cannabis, with some considerable caveats depending on which part of the country you live in.

On Wednesday, Oct. 17 the country will mark a historic moment: the end of the criminal prohibition on marijuana.

It also begins the 12-month march to edibles joining the list of permissible pot products -- the regulations for which Blair said are already in the works.

With the countdown to legal cannabis now measurable in hours, many retailers, police forces, and the general public are still curious and uncertain about how the rollout will go.

A battle is brewing over how Premier Doug Ford's government will divvy up the private sector's share of Ontario's retail cannabis market.

Legislation that would allow companies to operate pot shops in Canada's largest province is now under scrutiny at Queen's Park and businesses are trying to influence key details of the bill. 

Once crucial aspect of the retail regime that's still to be decided: how many cannabis retail licences any one corporation can hold. Government officials say there will be a limit, but that limit has not yet been set. 

Canada's new law legalizing recreational cannabis goes into force on Wednesday. Here are five things about what's legal and what's not under this historic piece of legislation:

1. Can't vote, can't toke: The legal age for consuming cannabis is at least 18 or 19, depending on the province. The Justice Department says the age restrictions are in keeping with, "a strict legal framework for controlling the production, distribution, sale and possession of pot." Of the three priorities the department cites for accomplishing those goals, the top one is keeping cannabis "out of the hands of youth."

The world's major alcohol producers can no longer ignore the pot phenomenon, as young consumers may increasingly swap beer and cocktails for joints and cannabis-infused drinks.

Some have decisively seized the moment. Constellation Brands, maker of Corona beer and Svedka vodka, has poured $4 billion into the Canadian marijuana firm Canopy Growth.

The coming market is "potentially one of the most significant global growth opportunities of the next decade," said Constellation Chief Executive Robert Sands. Sales of legal marijuana and related products should reach $200 billion within 15 years and the market is opening "much more rapidly than originally anticipated," he said.

Canada is legalizing adult use of marijuana on Oct. 17 and will be the second and largest country to do so.

The federal government established the broad outline of the legalization law but left it up to provinces and territories to fill in some of the details – such as whether to allow home grows, to establish a legal purchase age of 18 or 19, and whether to sell through government-run pot shops or private outlets.

Here’s a look at how the industry will look, as well as some key differences between Canada’s approach and that of the nine U.S. states that have legalized so-called recreational marijuana:

Despite the fast approach of cannabis legalization in Canada, laws surrounding the drug remain ambiguous.

October 17th will mark the beginning of a grand experiment. Canada is only the seocnd country and first major economy to legalize recreational use.

Consequently, the regulations, law enforcement tactics, and market predications that will soon come into force are largely untested. It can be difficult to know just what will and what will not be safe or legally admissable once marijuana becomes legal. To help you out, we've compiled this list of things you should never do after October 17th.

While some of these items will definitely land you in legal trouble, others are precautionary measures.

With October 17, 2018, just around the corner, many Canadians are counting down the days to legalization. It won't be long before we will be able to purchase legal, recreational cannabis for the first time.

But many of us are still asking some important, practical questions about how exactly that will happen.

This blog will attempt to address those burning questions and provide a little bit of clarity about what you can expect in British Columbia — and how you can purchase legal cannabis — on October 17, 2018.

Where will I be able to purchase legal, recreational cannabis?

Don't expect new cannabis stores to pop up overnight... or even within the year.

On the eve of legalized recreational marijuana and concerns about supply shortage, one of Canada's largest producers believes automated machines will be the key to producing more cannabis. 

Leamington-based Aphria currently has supply agreements with every province and Yukon, boasting about plans to produce roughly 20,000 kilograms of marijuana a month by spring.

As they expand their footprint to 3 million square feet, they're constantly looking at automation to reduce costs and maintain quality, said co-founder John Cervini.

"It's what's made us the low-cost producer, helped us to maintain that low-cost producer status," he said during a recent tour of the facility. 

Legal cannabis goes on sale next Wednesday and while New Brunswick has announced what its prices will be, Nova Scotia has not.  

Some Haligonians say they’re not in a rush to check out the NSLC cannabis outlets.

"I was actually thinking about checking this out depending on how crowded it is,” said Sheroz Kulkarni.“If there is a huge line up, obviously I'm gonna wait for a week.” Erica Baker doesn’t plan on making a special trip. “If I happen to be at the liquor store at some point, I might go look, but I don't think I’ll be rushing.”

For Maritimers who do go, it will be to government-run retail locations - or online.

Cannabis consumers must be 19 years of age or older and can only buy 30 grams of dried product at a time.
