But there are still concerns, including the willingness of police forces to tackle drug-trafficking.
Canadian provinces and municipalities have been preparing for the ban on cannabis for months
Provinces and territories are responsible for providing many details on where cannabis can be purchased and consumed within its jurisdiction.
This has created a patchwork of laws across the country as the jurisdiction chooses more or less restrictive frameworks for the sale and use of cannabis.
Shops in Newfoundland, the easternmost time zone of Canada, were opened at midnight, the first legal sale of cannabis in the country.
How ready is Canada for cannabis?
Some key issues surrounding the question of how legal cannabis will work in Canada leave unanswered questions unanswered.
A number of analysts forecast in the first year of legalization a shortage of marijuana production and licensing continue to rise to meet demand.
And the market itself is still in its infancy.
Ontario, Canada's most populous province, will not begin opening retail stores until next spring, though residents can order cannabis online.
British Columbia, one of the highest cannabis provinces, will only have one single legal store open Wednesday.
Until retail locations become more widely available, some unlicensed cannabis retailers that thrive in the years since the first law may remain open.

A measure of success – whether Justin Trudeau's legalization will win ahead of the 2019 federal election – depends on whether he lives up to his declared goals: limiting adolescent access to the teenagers who are among the strongest users in Canada – reducing the number of young people Burden of cannabis laws on the justice system and undercutting of the illegal market for the drug.
And if the results are positive, other countries might be more willing to follow the example.
Why is Canada? Legalization of Cannabis
Legalization Meets Election Promise of Prime Minister Justin Trudeau, Leader of the Ruling Liberal Party of 2015.
The Prime Minister has argued that Canada's nearly one-hundred-year-old laws criminalizing the use of the drug were ineffective,
He said the new law seeks to keep drugs out of the hands of minors and profiteers from the hands of criminals.

Cannabis possession became a criminal offense in Canada in 1923, and since 2001 medical use has been legal.
Following in the footsteps of Uruguay, the first country in the world to legalize the sale of cannabis for recreational use in 2013, a number of US states have also voted to ban the ban.
Medical marijuana is also gaining ground in many European countries.  What are the new rules for cannabis?
Adults can purchase cannabis oil, seeds, and plants and dried cannabis from licensed manufacturers and retailers and have up to 30 grams (one ounce) of dried cannabis in public equivalent.

Punishments for some transgressions will be severe. Someone who was caught selling the drug to a minor was imprisoned for up to 14 years.

What is there? it is legal?
The end of the ban will not end the legal and health concerns of marijuana.
On Monday, the Canadian Medical Association Journal published an editorial that published the legalization "a national, uncontrolled experiment in which the profits of cannabis producers and tax revenues are directed against the health of Canadians."
There are also some legal wrinkles that have to be solved.
Canada has introduced new drug-related driving offenses, but has doubts about the reliability of the screening technology and the risk of the cases being drugged.
Federal statistics show that about half of cannabis users who take marijuana do not believe that their driving is impaired.
Government officials told reporters on Tuesday that they are considering a fast track trial to seek pardon for those convicted of possession. Currently there are about 500,000 Canadians with existing criminal records to the possession.
The change in national drug policy has also caused headaches with the US, where the drug remains a controlled substance.
On Tuesday, the US Border Guard said border guards will have "a lot of leeway" to determine who (19659007) border guards can ask Canadians if they smoke, and deny them entry if they believe they did in the US.
Canada has also installed at all airports and border signs intersections to warn travelers that crossing international borders with the drug remains illegal.
