Sorry to hear you’re not feeling well! Your question is a bit of a complicated one. Sick time policies are different from one employer to the next, but here’s what the guide to the Labour Standards Code says:
Sick Leave
Employees are entitled to receive up to three days, unpaid sick leave each year. This leave may be used to care for an ill parent, child, or family member. It can also be used for medical, dental, or other similar appointments. An employee who is denied sick leave may make a complaint with the Labour Standards Division.
It also depends on what the illness is, as there are different rules for communicable diseases covered under health legislation. Regardless of your health at the time, report an injury or an occupational disease as soon as possible. You may well be entitled to compensation.
Get well soon.
