If I correctly understand your question, you're looking for the Canadian Distributor. While I don't know for certain, it appears that Mossberg lists Inland Pacific Distributors as their Canadian distributor.
Depending on the nature of your inquiry, they may not deal with you directly. Most distributors want the general public to go through their authorized dealer network for most issues. All distributors formulate their own policies on such matters, but generally they only talk to end users about stuff that's not easily handled by the authorized dealers, such as:
whether or not they'll import a new model into Canada
warranty issues that go beyond a simple repair
problems with their authorized dealers
questions about their products that dealers can't answer
