GTA cellphone mobility data shows
- movement dropped 1% post-lockdown
- areas with more essential workers = more mobility
- affluent core, people who can work from home = moving the least
Our story challenges the province's messaging in a few ways.

This week, CMOH Dr. David Williams lectured Ontarians to stop socializing: "people may say, well, whatever. No, it’s not whatever. You’ve got to do whatever you can to stop it.”
But a lot of movement -- and infection risk -- seems to be born by workers who don't have a choice.

Meanwhile, a lot of people appear to be heeding public health advice on holidays -- particularly in poorer areas.

The housing suitability & essential worker case growth charts were presented by @SteiniBrown, co-chair of Ontario’s COVID-19 Science Advisory Table, at the same briefing last week.
Brown emphasized the need to provide supports if we want to control this second wave.
