Bill C-17 was introduced and passed in 1991 by the Kim Campbell
Conservatives. It created expanded powers for the minister of justice
to restrict any firearm and prohibit those not "commonly used in Canada
for hunting or sporting purposes". Other sections included new powers
for police to search the homes of certain types of "gun collectors", and
placed limits on magazine sizes (10 rounds for semi-auto pistols and 5
for centre-fire semi-auto rifles and shotguns, but there are a few
exceptions).

(Orders in Council) have been thrown out.
Bill C-17 was preceded by Bill C-80 which died on the Order Paper.
