As quoted it IS R Nicholls, they are THE importer for HK in Canada; although you may be able to get a US made version from a place like I Run Guns. Problem is then the barrel will only be a 16" barrel.
However to be fair; when I talked with one of the R Nicholls guys just after Shot Show (doing orders for my old job); he had said they are already talking with the RCMP about submitting a sample for approval, so YES they are working on it.
I would not even expect to see these rifles for sale in the USA before 2 years, plus the RCMP taking their time on approving things (although due to HK being very familiar with Sporting / Mil. versions of guns due to THEIR gun laws) I would not expect any issues with a non restricted (or restricted due to barrel length) FRT for it, assuming those kinds of guns are still legal to own at that time!
This is one of those things that will take some time, I will definitely be picking one up (probably basic with the nicer stock) if black (or tan

) rifles are still legal to own in 2-3 years!
