Where do you live? Are you in Toronto, or "GTA"? Are you reflecting on the past 45 years, or focusing on the past 4 or 5 years?
Every year we get progressively less bad winters in Toronto. I think 2018 going into 2019 was the last proper bad winter for winter riding with a lot of precipitation, snowfall, and warm to flash freezing back and forth. That was a miserable winter for those who like winter riding. We've had great winters since then.
Been doing it 17 years, so I wasn't there for the generation that had to walk in 28 feet of snow uphill in both directions to get to school, nor do I think those historical experiences are relevant to today's inner city riders with the way climate change and municipal equipment and policies are going. Every year we typically see winters getting warmer and dryer in the city, and city hall has been (for better or worse) getting progressively more aggressive with proactively overspraying and clearing the roads.
We're 50 days into the new year, and I'm at 600-800 km this year. It's not much, but most days I'm only doing 5 km/day to pickup takeout or something from a store, or 30 km/day if I have an errand to run. I'm riding more days than I'm not, even if it's not much riding, because we've seen far more clear, dry, safe days in the city than we've seen wet or snowy ones.
