Canada’s health regulator is planning to ban a controversial neonicotinoid pesticide, which it says has contaminated waterways and killed important aquatic insects.

wants to ban virtually all uses of the pesticide .

It said Imidacloprid poses risks to Canada’s aquatic .

Studies have linked neonicotinoid use to deaths around the world, although whether it is to blame for colony collapse is still being debated.

In its environmental assessment, Health Canada said it frequently detected Imidacloprid in Canadian waterways. In agricultural regions where the pesticide was heavily used, the regulator detected levels “well above concentrations that may result in toxic effects to insects”.

work by affecting the central nervous system of insects and are frequently used on corn and canola crops, as well as on everything from lawns and Christmas trees to flea treatments for pets.

‘Long-time coming’

But studies cited by Health Canada have shown that they can also kill off beneficial insects, such as those eaten by fish, by seeping through the ground into rivers and streams.

“These insects are an important part of the ecosystem, including as a food source for fish, birds and other animals,” Health Canada wrote in its ban proposal.

Health Canada said it intends to phase out almost all uses of Imidacloprid and will re-evaluate the use of two other insecticides.

The public has 90 days to comment on the proposal before the regulator publishes its final decision.

The move away from neonicotinoid pesticides in Canada has been a long-time coming, beekeepers say.

Murray Borer, an apiarist and president of his regional beekeeper’s association, told the BBC his industry has been decimated by the pesticide. He says even if it doesn’t kill them, it makes them weak and susceptible to parasites like the mite.

“I believe the ban is a good step and it’s nice to a see a government actually taking action but that being said, it should have been done a long time ago,” he said.

The proposed ban does not mention , as the pesticide’s affect on bee deaths is still being evaluated by the regulator. But beekeepers say reducing its use for any reason is welcome.

In 2013, Health Canada published a report linking neonicotinoid use in corn crops to bee deaths in corn-growing regions of Quebec and Ontario during the spring of 2012. Two years later, it announced it would be re-evaluating the pesticide’s use.

The EU issued a moratorium on neonicotinoids in 2013, a decision the UK did not support, citing insufficient scientific evidence. Two years later, the ban was lifted in Britain following an emergency application by the National Farmers Union to protect the oilseed rape crop.
