Canada bound BWB tolls are going up to match the US bound tolls, and match the tolls charged at Mr. M's rip off bridge in Detroit.
CBP got real aggressive with charging the fee mid way thru last year, I hardly ever had to pay it and then it was every time. I opened an account with CBP and got the transponder which ain't cheap either but it beats the hassle of paying each time.
Of note, over half of that fee you pay is for the USDA, whether you have a food load or not, you pay the APHIS USDA fee each time you cross into the US.
