Senators voted Tuesday night to pass the government's legislation to legalize cannabis - Bill C-45 - by 52-29.
It was clear, however, that there are still more questions than answers about what Canada's nascent legal-pot landscape will look like - how police will test motorists, what to do about those with prior marijuana convictions and just how the rules governing home cultivation will work.
Canada has become the second country to legalise recreational marijuana nationwide and the first G-7 country to do so.
Federal regulation will allow those 18 and older to purchase marijuana in various forms, including edibles and cannabis-infused foods, but some provinces have set the age at 19.
While a Sky Data poll has found most Britons agree that cannabis should be made legal for medicinal purposes, it is a far more even split when it comes to recreational use - with 41% in favour and 40% against. Canadians will also be allowed to grow small amounts of pot for recreational use.

He added, "We don't have to prosecute them, but then we're not prosecuting them for coming in illegally". Late on Sunday, Nielsen tweeted : " We do not have a policy of separating families at the border ".
Marijuana will not be sold in the same location as alcohol or tobacco.
Conservative senators also raised other concerns, such as slower United States border crossings, that kept the bill in the upper house for about seven months. Its "historic" approval officially ends the country's nearly century-long prohibition on the substance.
"A fearless move on the part of the government", he told CBC.
"Now we can start to tackle some of the harms of cannabis", said Sen.
When asked if the government is considering amnesty or pardons for people who have criminal records for marijuana crimes, Ms. Wilson-Raybould said the issue is under "consideration" by Public Safety Minister Ralph Goodale.
Conservative senators remained staunchly opposed to legalisation.
"When you normalize the use of marijuana and you're a young person and you had certain reservations because of the smple fact that it was illegal, there's, I believe, a propensity to have somebody be more inclined to use it".
