It can be difficult. The Uniter only found out about this massive protest by seeing a passing facebook post which was then deleted by fb, with google or even duck duck go searches fruitless so here are two places online which keep tabs on events in Canada.
– where the Nurses Walkout event information could be found after it disappeared from FB

If there is an event you do not see , please contact The Uniter so we can make sure others know about it:

Thank you!
