First off, too many powerful weapons and ammo. Stick to one and the knife then split the ammo in half. On a side note why does he use an assault rifle shotgun and revolver if he's a hunter?! Surely he'd be more proficient in the use of hunting rifles and stuff like that.
Second "Occupation: Survivalist" ? What is this DayZ?
Thirdly the group is nowhere near Canada so he'd not "stumble across homestead" after vanishing into the wilderness of Canada.
Fourthly do I really need to explain why having "One of the greatest hunters in the world" who survives the harsh conditions of not just Africa but Canada AS WELL? If he had perhaps spent his whole life in Africa then came to the US on vacation when the outbreak came then I maybe more lenient as he'd not be used to US and Canadian conditions. 
As it stands there's a lot about this App that screams OP and suggests you're more interested in killing zombies than character and plot development.
If you seriously want to join make a new application with a more believable and realistic character.
