Travel to Canada

As a dual citizen - much of your service will most likely be on Bell (was in Northern Ontario in July), and 5G service - rural isn't bad these days either.  You'll have a difficult time hitting Rogers - I have had it work in the past.  +300Mbps in Sault Ste. Marie, ON.  

Brockville is in that 'gap' between Kingston and Montreal.  Service was 'meh' a few years back when I crossed the border near Alexandria Bay.  TBH, it was worse in upstate NY on T-Mobile and I was actually often roaming on a weak site (or 2) from Canada.  I didn't spend much time near that area - but travelled down to Cobourg and had no issues.  Don't forget after ~5GB you'll be throttled.
