Conservatives still say the Liberals rushed legalization, and that some tweaks might be necessary depending on how things play out over the next year. The NDP argues the Liberals should fully expunge the criminal records of those with past convictions for minor cannabis offences, rather than just offering pardons.

Still, it seems unlikely that either party will make a big issue of legal weed in next year’s federal election campaign.

People are wanting to comply, they're just having a little bit of trouble figuring out how

“We recognize the reality now, so I do not intend to go back and make marijuana illegal again,” Conservative Party Leader Andrew Scheer told a Quebec radio station last month.

But that’s not to say it’s all smooth sailing ahead. Now that cannabis is legal, the battleground will likely move to the courts, where many features of the Liberals’ cannabis laws are destined for legal challenges.

In some cases, having the courts settle policy is by design. For example, the federal government decided not to intervene when Manitoba and Quebec announced a ban on home cultivation (the federal legislation allows up to four cannabis plants), instead saying it will wait for residents to challenge the ban.

On other matters, such as drug-impaired driving, it’s simply unavoidable that the courts will play a big role as lawyers and their clients look for weak points in the laws.

It will likely be slow going, as these cases typically take years to work their way through the justice system. But if you’re looking for how Canada’s cannabis regime could still see significant changes, here’s what to keep an eye on.
