We crossed Ontario during our USA trip. We drove into Canada and our first stop was Sarnia. Our group stayed in an Airbnb on Lake Huron where we canoed. We moved onto Hamilton which was ok but not as good as Toronto. I went to the top of the CN Tower, the view was awesome. Great city , beautiful province. Also Niagara was worth the stop.
An exhilarating city, Very diverse and friendly. The CN tower was amazing from the SKYPOD. the history of Casa Loma, was amazing during the tour .
City of Ontario is a big sizable city. This Ontario often confuse with Ontario, Canada. Funny since CA can be mistake as Canada too for short phase. This Ontario is known for three things 1) Ontario Airport - One of major domestic Airport in Socal. After LAX Ontario are next to next with burbank. 2) Warehouse and Big Rigs - Ontario is known for massive warehouse which translate lots of big rigs... I never see so many big rigs except near the Port of L.A. 3) Ontario Mill - This probably only thing keep the local keep coming here beside going on business trip or working here. The outlet is pretty big and is indoor. Despite the large size, not too many people live here. Most prefer the surround city.
I have been to Ontario a few times and passed it many more on the way to/from Vegas or San Bernadino. It is located right off the 15 freeway and southwest of San Bernadino, or west of the Inland Empire. There is a HUGE shopping mall, Ontario Mills that has outlets and is very nice. Good restaurants and really great deals! There are many hotels in the area and easy access to the freeways.
