Your in the Owen Sound area right?
About an hour South. I think one thing that affects our weather is that we're the highest point in Ontario. We can literally drive 5 km in any direction and have completely different weather.
I c hanged my appointments in Toronto back in December telling them that January was just a bad time for me to attempt to get to Toronto. I think they thought I exaggerated and if I had kept the appts, I wouldn't have made it as Toronto was fairly mild and we were without power and freezing rain/ice everywhere with 120 km/h winds.
I also have regular appointments in Newmarket and I'm not sure they get it either. I can leave Newmarket on dry roads and sunny skies and 10 km from home be in white out conditions down to 40 km/h with the 4 ways on.
Still. It's not a big deal, just something we accept and get used to.
