The question is really what the vacation promise is.
If this is so many days or weeks of paid vacation, accrued based on active service, then there would be no requirement to accrue this time when the person is off on STD.
However, if the promise is vacation pay at some percent, then if the contact of employment includes the provision of STD benefits, then these benefits would be vacationable in Ontario, for example. However, STD benefits would not be vacationable in BC, where the vacation promise is a percent of vacationable earnings.
