Moose hunting begins during August in Canada, but the rut usually begins close to the end of September/ beginning of October. The farther north you are the earlier they rut. During pre-rut, your best chances is to cover ground looking at meadows, swamps, sub-alpine areas, cut lines, and slashes coupled with calling to find moose. During the rut, cow calling will be the most successful strategy. Remember to hang out around the swamps and wallows. Some people like bull grunting but most guides prefer cow calling and it seems like that is your best strategy to bag a bull moose.
