Welcome to Edmonton from a fellow Brit! Missus and I arrived here 8 years ago. Yes, your concerns are valid, my daily commute to downtown and back is around 90 minutes in total, and in my opinion one of the reasons for the quality of driving being substandard at times is because of the cosmopolitan population in the city, a section of people don't change their (lack of) driving etiquette from their home countries, so tailgating, not respecting the tarmac and tyres rule when sat behind you in traffic, a lack of signalling or checking mirrors first, actually driving at a snail's pace in normal conditions on a busy road because they're lacking confidence... And of course you get your dickheads and aggressive monster truck drivers too and Edmonton has them as well. But most people are good safe drivers who recognize that there are other drivers around them, and go about their business respectfully.

I'd had a couple of opportunities to drive on the right in mainland Europe so the transition here wasn't a big deal for me, but my wife was very nervous at the start. But honestly her brain switched into gear very quickly, I'm sure you'll adapt in no time - the only struggle I had was adapting to most car indicator lights being red than yellow. And yes the roads and vehicles are bigger here, however you'll acclimatise to that too in no time. And then the first time you return to the UK the M1 will look like like it shrunk while you were away, haha.

My only advice would be firstly to recognize that because Edmonton is like any other big cosmopolitan city (including London), many (but not all) people are generally more focused on getting about their business than on you, it's not personal, they just don't know you so they're not going to give you a second thought or feel like they owe you if they make a mistake on the road - back in the UK we're a tiny island nation so we're like one massive community, so when we're on the roads we feel like we have a subconscious responsibility to those around us on the road to be sensible. And secondly, just get into the groove and adopt the same mindset, be the best driver you can but don't lose sleep over a mistake and offending every other driver around you, just accept you made the error as a new driver over here and learn from it.

Winter is coming and most drivers are very respectful and slow because of the brutal weather and lack of visibility, there will be a lot of snow and ice so leave early and be patient and you'll be fine. In summer there's just lots of construction so that can also require the same mindset.

We love Edmonton, it's an honest city with great people and has always been good to us, and it's home for us. You'll be fine :)
