Yeah - "something is worth what someone will pay for it." The market decides.
If the Garand hits the restricted list, watch the bottom fall out of the market PDQ.
I expect the M1 won't hit the restricted list unless they ban all semi-autos. In the 1994 legislation, the M1 was so popular they exempted the 8 round en-bloc clip specifically in legislation because of the uproar it would have cause among military rifle match shooters, hunters, inuit, etc. who were (and still are) using them all over.
Besides, it's not black, it has no pistol grip, it fires a full-power cartridge, typically not in sustained rapid fire. It has no detachable magazine and does not readily take optics. As guns go, it does not have the "evil" look.
Long before they ban the M1, they would ban M14 clones. Which would suck, as I like those just as well. Let's hope they don't, but that idiot who killed police in Moncton with one has likely made it a target.
If I were a betting man, all the NR .223 and 7.62x39 black rifles are at risk to go restricted - stuff like the Bushmaster ACR, BCL102, Tavor, etc. I expect the return of having to call in for an ATT, because they can claim they reversed Harper's "lightening" of gun laws, even though AT's are never refused and are just an excuse to hire bureaucrats.
I expect some other things like longer wait times for restricteds in some provinces (not ontario where it's already like 3 months due to ineptitude). I also suspect they may mandate some form of even more thorough and time consuming background check process for RPAL shooters - not sure if that will mean at RPAL renewal, or at every purchase - who knows?
Sorry for the hijack.
