For most workers in Ontario, the first Monday in August and Easter Monday are paid days off work. However, neither is a “public holiday” as defined by the Ontario Employment Standards Act, 2000. What that means is that the rules surrounding statutory holiday pay do not apply to “the Civic holiday” or to “Easter Monday.” But, that does not necessarily mean that they cannot be treated by any particular employer as a ‘holiday;' on this point see the post Any Day Can be a Holiday.
The points above provide an opening to discuss what the rules surrounding such holidays actually are.
