  • Armando G.
    "We were residents in North Ontario for a little over two years. We moved there during the pandemic so streets were calm and quiet since schools were not in session at the time. This is definitely not the case anymore. Lots of street racing and impatient, reckless drivers on the roads here. Good luck trying to navigate your way around the city during certain hours of the day as school traffic is horrendous. There seems to be a school on every block. This city doesn’t offer many decent grocery stores or restaurants either. We did all our shopping or dining in other surrounding areas. The extreme heat, high electricity bills, constant traffic and wild winds is what finally did it for us. Overall not a great place to live."
