Montreal wants to ban use of herbicide glyphosate, calling it a public health issue

Montreal plans to ban the use of glyphosate,a commonly used herbicide marketed primarily under the trade name Roundup,by the end of the year.

In 2015, the World Health Organizationdetermined thatglyphosate is a probable carcinogen.

Laurence Lavigne-Lalonde, a Projet Montral councillor and the executive committee member in charge of urban agriculture, said that classification means there is no longer "any reason not to protect the health of Montrealers and farmers who use this product."

"Failing to act would be irresponsible," she said.

She said Mayor Valrie Plante's administration hopes the gesture will inspire other Quebec municipalities to follow suit.

The City of Montreal banned neonicotinoid pesticides in 2015 an effort to protect bees. That bylaw will be amended, extending the ban to glyphosate.

Lavigne-Lalondetold CBCNews that the product is already restricted and requires a permit to use.

"Now we want to ban it for everybody," she said.

Plante's administration is concerned about the quality of soiland the levels glyphosate found in food andwaterways.

Montreal is followingAustria and Vietnam, the countries banned glyphosate earlier this year. Germany announced Wednesdayit will do the same at the end of 2023.

The effort to ban the substance in France by 2021 has stalled but, regardless, Lavigne-Lalonde said Montreal is part of a movement.

"We think we need to push people to think about this issue and take concrete action," she said.

Health Canada approves glyphosate

Health Canada reapproved the continued use of glyphosatein 2017.

That decision sparked plenty of backlash, as opponents said lobbyists for thecompany Bayer are influencing decision-makers.

Glyphosate, one of the most common herbicides used in the world, is in more than 130 products sold in Canada and has widespread use by farmers to keep weeds out of their crops.

Under Quebec law, municipalities can ban the use of chemicals, but not their sale.

Quebec should ban it, groups say

Banning glyphosate use in the province's largest city is a step in the right direction, saysThibaultRehn, co-ordinator of Villigance OGM, a group aimed at raising awareness about pesticide use.

Rehn said he hopes the province will take action against glyphosate by either banning it entirely or, at the very least, restricting its use to protect citizens.

"We would like that all the cities in Quebec do the same [as Montreal]," he said. "We want the government of Quebec to ban this product."

Nadine Bachand, a project manager with the environmental groupquiterre, wants the ban to extend across the province.quiterrehas alreadyasked Quebec to enact a provincial ban, she said.

"We think it's a strong message that Montreal is sending to its citizens," she said.

In a press conference on Thursday, Premier Franois Legault said he was "concerned" by the potentially harmful effects ofglyphosate but said that more investigation was needed before his government would take any action.

"We're not there yet," he said of a proposed ban on the chemical. "But we won't rule it out."

Legault suggested that banning the product might have an adverse effect on Quebec farmers and said he would wait on the findings of aparliamentary commission on the use of pesticidesscheduled at the end of this month.

Method of last resort

Anne Charpentier, director of Montreal's Botanical Gardens told CBCNews that the operationsometimes usesglyphosate as a last resort in an effort to subdue an invasive plant called Dog Strangling Vine.

She saidthe gardens have been trying other ways to deal with the problem for 25 years.

Charpentiersaid it's important to protect the plants inside the gardens from aggressive species that could threaten their growth.

Bayer defends glyphosate

The use of glyphosate has led to several lawsuits against Bayer, which now owns agricultural giant Monsanto, as cancer patients seek compensation in both Canada and the United States. A Quebec woman is among those suing for compensation.

Monsanto and Bayer face over 13,400 lawsuits in the U.S. alone.

Bayer claims the product is not carcinogenic and is safe for humans. The company defends its use extensively on its website.

"Glyphosate is one of the most studied herbicides in the world and, like all crop protection products, it is subject to rigorous testing and oversight by regulatory authorities," the company states.

That "rigorous testing" by various government bodies has proven that glyphosate and glyphosate-based herbicides are safe when used as directed, the site says.
