Not pistols (most at any rate)
As a basic it must shoot above 366fps and below 500fps.
all in all most long guns will get in. The pistols that are comming in are modified to fire high enough. Normally youll seem em sold with silencers to hide the long inner barrels they put in them to boost the fps enough to cross the border. Look at the WE pistols at TA as an example. If you want a full metal pistol best bet is to buy in canada. Rifles you can source outside but atvthe current exchange rate there are not any savings to be had.
ordering a metal lower or pistol frame or the upper from a mac11 or other guns where the upper is restricted or even pistol barrels (outers) under 110mm (prety sure thats the length at least) will be considered restricted as always.
so to summerize, most everything that was restricted is restricted aside from full guns shooting above 366 and below 500.
you can say import a tm vsr 10, but will have to have it upgraded and then have some documentation stating the gun has been upgraded to comply with canadian import laws and the tested velocity and such.
