With a textured green feature wall, and white tins neatly arranged on the back shelves, the Wealth Shop Dispensary near Vancouver's leafy University of British Columbia campus, feels every bit like an upmarket health store.

But many Australians might be surprised at what's on sale inside.

As one of the city's licensed medicinal marijuana dispensaries, the Wealth shop sells cannabis.

Australian manager Zac Bora says fresh flower is the most popular product.

"We carry everything from traditional flower that you're used to seeing people roll and smoke, moving onto more advanced products like extracts, capsules and bathbombs," he said.

"Anything that can have cannabis in it, we try to have."

Mr Bora said he was drawn to Canada's cannabis culture after moving to Vancouver to study.

Now a passionate advocate for the cause, he sells marijuana to hundreds of people every day.

"Our most consistent demographic is actually seniors and parents, so kind of hitting around the 40 to 70 mark," he said.

Medicinal marijuana has been legal in Canada since 2001, but now the country looks set to go one step further, with the Senate signing off on a heavily amended version of a plan put forward by Prime Minister Justin Trudeau to legalise recreational marijuana.

But while his Liberal government had promised to have the law changed by July 1, that looks unlikely, with the amendments requiring the tick of approval from the lower house, before being sent for royal ascent.

The plan takes a leaf from Australia's tobacco laws, with commercially grown cannabis to be sold in plain packaging, with no images or graphics, and a prominent health warning.

Provinces will be responsible for sales and distribution, with each taking a slightly different approach.

British Columbia's Solicitor-General Mike Farnworth told 9NEWS it was proving a complex issue, with laws governing driving, enforcement and licensing all requiring attention.

"We've met with people who are illegal now who want to be legal, local government has concerns around such things as closeness to schools," he said.

"Do landlords have the right to say no to someone growing or consuming cannabis in a rental unit?"

The US border also looks set to pose a problem.

Marijuana will be legal in both Canada and neighbouring Washington state, but not the border itself, meaning those attempting to cross carrying cannabis risk being apprehended.

"That is going to be a real issue, and it's one we've raised with the American authorities at both the provincial and federal level, and they have indicated to us they have zero interest in dealing with that," Mr Farnworth said.

And not everyone in Canada supports the move to end prohibition.

Conservative MPs voted against the change, while perhaps somewhat surprisingly, the Marijuana Party has also voiced concerns.

Mick Mann, who has contested numerous elections for the party, questioned whether the government has been motivated by public safety, or by money.

"This isn't really legalisation, this is the re-illegalisation of cannabis," he said.

"It's more of a corporate takeover from the government's point of view."

Mike Farnworth said he expects cannabis will eventually generate revenue for government, but that's likely to take a number of years.

Not that there's any shortage of people looming to cash in on Canada's growing cannabis industry.

"There's a gold rush mentality out there, and sometimes that's a challenge to deal with", he said.

Some Australian MPs are keeping a keen eye on Canada's cannabis experiment.

Victoria's Fiona Patten believes it's a model that could be copied here.

"I think the model Canada is presenting is an excellent model for Australia", she said.
