If you have insurance with Wawanesa, and have gotten your renewal papers, does our premium go up this year? Or was it just me?

I have to renew my policy this March and my premium goes up $35. The letter said that it's because the cost of doing business has gone up, yada, yada... The letter didn't say it was my fault but I'm so sure the reason my premium went up was because I filed a claim with them last year. They have finished their investigation and I was not at fault. 100% was the other drivers' (2 of them hit me in a red light chain collision) fault. But that didn't keep them from raising my premium. My car is getting older so shouldn't my premium goes down? Instead of up?

 

mine went up.
