"Nothing has been done to address my concerns about the heavy metals in my rain after days of seeding."
For a clearer picture she would need to take samples on many days, not just says when they are doing the cloud seeding. Samples on new years eve would be good too to see how much stuff the stupid fireworks put into the air...

I did some research into how the process works:
The planes combust silver iodide using flares to increase the rate of freezing up in the clouds. When this happens, the forming hailstones form faster and cannot use the rest of the water accessible to them in the cloud. That means there would be more small stones instead, sometimes melting as they fall from the sky. This is likely why many parts of the city saw a lot of small hail while some parts saw less (in overall number of stones falling) big hail.
Not every part of the city that was impacted got to experience the effects of the seeding because the storm likely started to change course too quickly. The planes usually do their work on the edges of the storm and not in the middle.
Silver iodide is found naturally in low concentrations around the planet. It’s speculated that the impact on the environment is low, but further research likely needs to be done.
As far as we know - as far as the province has told us - this is the only use for cloud seeding at all in the province. It’s funded by insurance companies and has been used as needed especially since the 2020 hailstorm. This project has also brought in many more radars for hail monitoring as well! Without those, we might not have gotten the emergency alert, for example.

That was my husband flying that route today.
