Prime Minister Justin Trudeau is reminding senators that his government was elected on a promise to legalize recreational marijuana — a subtle warning that they should not attempt to thwart the will of Canadians or the government they elected.

The reminder comes amid some uncertainty over the fate of the pot legalization bill as it faces a second reading vote in the Senate this evening.

While the unelected Senate exists to scrutinize and suggest improvements to bills passed by the House of Commons, Trudeau says Canadians voted to end the criminal prohibition on cannabis when they elected his Liberal government.

He says the criminal regime has not protected Canadian kids, who are among the highest under-age users of marijuana in developed countries, and has put up to $7 billion every year in the pockets of organized crime.

“The current system does not work,” Trudeau said following an event in New Brunswick. “This is not something that Canadians want to see continued.”
