Marija, looking for a babysitter in St. catharines southwest

I for the most part do not work when my son is not in day care. There are though, the occasional shifts that I cannot get out of. We are short staffed, and when needed, I work a 5pm-9pm shift, or recently, and 11am-3pm shift. I work in the mall, and with the up-coming holiday season, I believe that I will be needed at work more often. On the 15th of October, I definitely will need a babysitter. I am looking for someone that is reliable, that I can use for years
