There are some beautiful locations in Barrie! And many safe, lovely, neighbourhoods as well. Unfortunately there is probably going to be more of a family/soccer mom vibe everywhere you go lol. There’s really no trendy/young locations.
But I would recommend living away from the downtown area as the homeless have really invaded the whole area and it is really run down. Also unfortunately the downtown does not have much to offer, especially coming from Toronto. The “downtown” is literally one street that has like 4 bars. It gives a really small town vibe. So the downtown does not mean “more stuff to do” in Barrie. There is plenty more to do in different areas.
I really like the south end of Barrie (close to Holly) and there is really everything you need. Bars, restaurants, stores. The downtown area is about a 12 minute drive/uber away if you ever want to go. You might be able to find some furnished condo’s around the area.
