As far as Home Stores go, I would say it is okay. I'm comparing between the Home Depot which is across the street. Something about Rona irks me, not sure if it's the terrible music they play or lack of expertise in the staff.
They do have comfy patio furniture for sale though, and is more appealing to the eye than Orange and Grey. At the same time, something about Home Depot is going to draw me back there, although they are very similar.
I would recommend checking out both, and the Canadian Tire on premises if you're looking for something specific because they carry the same stuff.
There is a hot dog cart and a picnic table to eat, but also in the BACK of the parking lot is a resident BBQ cart with Pulled Pork Burgers etc. I wish I noticed it earlier!
