I found out that The Home Depot holds regular free kiddie workshops every month. This month it was about building an EMS truck. It will be held on Saturday October 4, 2014. It's open for kids from 4 to 12 years old. They will need a hammer, glue and paint brushes for the project but all these materials are provided by The Home Depot workshop leaders. Kids should be accompanied by an adult.
There was an online registration but sadly it was already filled up. However, the site did say that we can still come to our chosen branch and register in person. The workshop starts at 10:00am. I guess depending on our schedule on Saturday, we can try to drop by our nearby branch Edmonton South Common at 2020-101 Street N.W., Edmonton.
