However, given Canada's licencing system, and my suspicion that Keffals does not have an RPAL, the mag limit stuff would just be another charge on top of many, in the event that Keffals was indeed in possession of this Spanish pistol.
The warrant listed and their likely meaning:
CC 85(1)(a) Use Firearm/Commit Indictable Offence
-Discharge of Firearm to kill his mother
CC 86(1) Use/Store Firearm Carelessly
-Discharge of restricted firearm outside of approve range
CC 91(2) Unlicensed Person Possess Prohibited/Restricted Weapon
-Did not have a license to possess restricted firearms
CC 264.1(1)(a) Uttering Threats/Deaths or Bodily Harm
-Death threats to city councils
In Canada, if you have a PAL or RPAL, you get flagged whenever this happens (even at traffic stops) that says you own firearms (and if they are registered, they are also listed). His name didn't come up in their interna; search, so his possession would defacto be unlicensed. For the magazine not being charged at the moment of the warrant, the police can't know that for sure unless they see the magazine being loaded/unloaded more then 10 times.
As an example of how Canada's firearms law is very byzantine and strange in general, there's this weird loophole where the magazine restrictions are applied for the firearm in which the magazine is designed to be used, rather than the firearm in which the magazine is being used, so when an AR pistol was released that used mags which could be fitted in any AR, it essentially legalized 10-round mags for the whole AR ecosystem.
The magazine being legal/illegal on its own is good applied law (not that the law itself is good, mag laws limits are retarded), as its simpler to say that this magazine by itself is illegal, then when it enters this one weapon it becomes illegal. For example glocks mags are limited to 10 rounds, but a Ruger PCC can take them and they are rifles, so if the law was the strictest form, then glock mags would need to be pinned to 5. There's also the niche case where a bolt gun magazine (unlimited) can enter a semi-automatic rifle, and if that happens, the magazine itself is still legal. An example is fitting more then 10 9mm in a .40S&W magazine, which is legal so long as you do not modify the magazine, such as the feed lips.
My personal theory is that his dad legally owned one before he died and the police couldn't find any records of it being transferred/sold after death
It would be registered and generally a hard search would be done if the police can not find it. When a parent passes, the local police/RCMP will hold on to the firearms then either give them back if the individual is or gets licensed, or they destroy them. If his dad had more then one property, it would be easier to be loss/stolen, but restricted firearms should have their current address at the moment of death, so unless he moved without notification, it should have been found.
They are in Ontario not Alberta. Bolt actions and pump shotguns is the only shit you can really own as a civilian.
You can have more in Ontario then Alberta, Ontario is the only province that does not require you to be a member of a gun range to purchase Restricted Firearms with a RPAL. ALL other provinces, even Alberta and Saskatchewan require at least 1 gun club membership. The only province with worst laws is Quebec with a 30 day after purchase registration on non-restricted, but you can technically leave the province every 29 days, sell it to a guy and buy it back the same day, then stay in Quebec for 29 more days, all while legally not being required to register,
DO NOT DO THIS. Alberta and Saskatchewan also require additional stuff for purchasing body armor (but a PAL should suffice) whereas Ontario does not.
The only thing that this search warrant would make sense if this was an unmodified M30.
Actually an unmodified M30 would include the overcapacity magazine limit, which is a prohibited device, so CC 88(1) should also be there.
