about this website
should i trust this website?
yeah. it uses Environment Canada data to show what Milton’s air is like.
it can’t tell you exactly what the air is like on your street.
is this an official government website?
no. Ehtoz is independent. it uses official government data, but it isn’t affiliated with Milton, Ontario, or Environment Canada.
who made this?
i’m Amrit Sharma. i live in Toronto and have spent more than a decade working on air quality and climate change.
i serve on the board of OpenAQ, helping make air-quality data more open and useful. the Asian Development Bank recently invited me to help develop a regional clean-air action plan with countries across South Asia.
i work at ecobee, designing grid-resiliency programs that help keep the lights on during heat waves and winter storms.
what should i do next?
enjoy the day. if you’ll be outside for hours, it’s worth checking again later.
if this helped, share it with a friend, neighbour, or group chat.
