A Conservative attempt to delay cannabis legalization was handily shot down in a 50 to 29 vote in the Senate on Monday night.

Conservative senators argued legalizing recreational marijuana could slow border travel, lead to an increase in Canadians turned away from the border for consuming a legal substance and even hurt Canada’s reputation and trade with the U.S.

Conservative Sen. Yonah Martin said legalization would be a “disastrous policy decision” that will “put us at odds” with the U.S.

But a majority in the upper chamber rejected that view and voted down Conservative Sen. Leo Housakos’ move to slow the passage of the bill until the government tables a report in Parliament outlining how it will deal with pot-related border issues.

Independent Sen. Andre Pratte said while inadmissibility is a problem, it’s not a new one, nor a big one.

Also arguing against the proposal, Liberal Sen. Art Eggleton pointed to an observation adopted at the bill’s committee review that says largely the same thing as the proposed amendment, but without asking for a delay.

That observation “calls on the federal government to present a plan in Parliament which will clearly and firmly communicate Canada’s position so as to minimize the impact on Bill C-45 on Canadian travellers.”

Eggleton said the Tories will try to “find any means they can for delaying” the bill, and have “gone overboard” in their suggestions this will suddenly impact Canada-U.S. travellers.

Conservative senators maintain the government is rushing its legislation to meet a political deadline.

Just before the evening sitting, Conservative Sen. Betty Unger sent out a series of tweets arguing that the Trudeau government is “forcing” the bill through quickly based on how the debate timeframe in the Senate was organized.

In debate Monday, Pratte argued that senators have now “looked at this bill extensively.”

Senators debate criminal penalties in the bill Tuesday and rules related to consumption on Wednesday. A final vote is expected Thursday.
