A Burnaby stream has been under close watch since an oily spill was discovered on the water's surface.
Greig Walsh first noticed the smell and the sheen on the water while biking home Friday night.
"It smells like a gas station, like when you're at a filling station and someone spilled some fuel," says Walsh.
"Actually a beaver came up in the water right in front of me, and he was swimming around, and there was an obvious oil slick on the top of the water."
What exactly went into the water is still unknown. Booms have been laid in the water to try and stop the slick from traveling to its final destination -- Burnaby Lake.
"It's a huge, huge concern," says Marcy Potter of the Wildlife Rescue Association.
The group is keeping tabs on the spill, especially considering the time of year.
"Babies are hatching right now. If any of them got oiled it would be a nightmare."
The city of Burnaby is monitoring the situation and says so far there have been no reports of animals in trouble.
"We have taken samples so till we go through analysis I can't tell you the solvent type but it is a solvent based product," says Dipak Dattan.
The city believes it's gotten to the source of the leak, but won't say where it comes from.
CTV has learned the local transit yard has been conducting its own investigation.
"We are treating it as if it came from our property," says Derek Zabel. "Right now we don't have any evidence."
The Coast Mountain Bus Company notes even if a fuel tank were leaking the amount would not be more than 400 litres.
"We're treating it as if it might be diesel, and may have come from our property, so right now we're cleaning it up to make sure this is something that has no effects on the environment."
Crews told CTV News on Saturday afternoon the spill appeared to be clearing up, but it will still be a few more days before it can be determined for sure what the substance is.
