Hi Tom!
A great song and loved listening to it. Being here is Australia, I only have a vague understanding of the Canadian truck blockade/strike, and now after hearing your song, I am intrigued to look up what it was about.
Musically, I detected a slight reggae feel to the percussion - maybe it was a shaker or the hi-hat. Also supported by the bass style. I LOVE reggae! A most enjoyable listen.
