I drive a lot. Approx 100 kms annually. Blizzaks are great for highway use with ice and snow covered and cold conditions. Never had a problem and I encounter a lot of conditions throughout Ontario. I find they are also very good for wet and heavy slush conditions as well. I travel from Windsor to Ottawa and north to the Soo. Based mostly in the GTA.
But, I must say, these are soft tires and when temps warm up and road conditions are bare, you do notice some squirm during heavy braking or a quick maneuver. It maybe even a little unsettling because you don't have this happen very often. I just mounted a new set on a new vehicle a little later in the season because of this. And will likely take them off when the season is consistently free of poor weather conditions.
