I am in Ontario, Canada and it was announced here yesterday that all public schools will be closed from now until April.
The main reason this has been implemented now is next week is our March Break (basically half-term for us) and traditionally ALOT of Canadians go on vacation down south, Florida etc. They are trying to stop people returning back to school straight after their holiday and spreading the virus quicker. They are reluctant to implement a travel ban.
Cases here are pretty low at the moment, but we all know that can change quickly. They are trying to slow the spread like other countries around the world.
Most parents are relieved from what I am hearing - the upcoming March Break travel was concerning, many have cancelled their holidays now and there is definitely social pressure to do so - it is now seen as irresponsible and selfish to continue with holiday plans in light of what has happened else where in the world.
In good news I have seen many offers of help from our local moms group on Facebook. People offering to watch kids for those that have less flexible jobs. I will probably share care with several neighbours on our street (as long as they haven't travelled recently). Many of us are immigrants and do not have extended family around to help, we will need our friends and neighbours so we can continue to work.
