Canadian source for a 1 Hole NVG shroud for a MICH helmet

[geologist]

Can anybody tell me where I can find a Canadian supplier of a 1 Hole NVG shroud for a MICH helmet? There are some on Amazon but they won't ship to Canada. I could try a 3 hole if that's all there is but drilling my helmet sounds like a hassle.

Thanks for any help/tips.
