You may find this of interest,

Since it is a Bell factory in Quebec, think we could quietly replace the Griffons with UH-1Y Venom aircraft instead?

Different class of machine.  Think UH-1Y as a militarized Bell 214ST, vice a 412CF.  70% bigger/heavier than a Griffon.  Heavily militarized.  Not close to being the same.
