You do not need to bring out the bones of a animal except for certain times of the year.
Check out the information on page 22 of the hunting regulation book
Meat Salvage
Wanton waste of big game meat is an extremely serious offense
punishable by a fine of up to $10,000 and 1 year in jail.
You must salvage all the edible meat of moose, caribou, sheep,
mountain goat, wild reindeer, deer, elk, bison, musk-oxen, and
spring black bear, for which seasons and bag limits exist. You
must also salvage either the hide or meat of beaver and ground
squirrel; for small game birds, the breast meat must be salvaged,
except for geese, cranes, and swans; for these you must salvage
the breast meat and the meat of the femur and tibia-fibula
(legs and thighs).
Big game meat you must salvage (excluding bear) includes:
• All of the neck meat.
• All of the brisket (chest meat).
• All of the meat of the ribs.
• Front quarters as far as the distal joint of the radius-ulna (knee).
• Hindquarters as far as the distal joint of the tibia-fibula (hock).
• All of the meat along the backbone between the front and
hindquarters (backstrap and tenderloins).
You are not required to salvage the meat of the head, guts, bones,
sinew, and meat left on the bones after close trimming, or meat
that has been damaged and made inedible by the bullet or arrow.
These portions of the animal may be left in the field because they
are not included in the definition of edible meat that must be
salvaged.
When the salvage of bear meat is required, you must salvage
the meat of the front quarters and hindquarters and meat along
the backbone (backstrap). When the salvage of brown bear meat is
required under a subsistence permit, you must also salvage all of the meat
of the neck, brisket and ribs. (See bear information, pages 24-28.) The
meat is required to be salvaged first, and bear hides and skulls (when
required to be salvaged) may be transported simultaneously with the last
load of meat.
For the butchering job I would make sure that I had at least 2 or 3 very sharp knifes and a way to resharpen them in the field.
