i bought all my latest gear there. bought a chest for $350+ and customs didnt to tax me so they let me go.
bought pads/blocker/trapper for $1800+ and customs taxed me, but it was just HST. still cheaper than buying the set locally by $500.
the HST will be the only thing you pay when crossing if the customs officer sends you in. buying locally, you still pay HST so no difference there.
