Someone fed someone a line about stores being corporately owned. The only time the corp would own any store and it would be on a very limited time basis, was if the "dealer" (kinda like a franchisee but different) died or went bankrupt or some situation like that.
There are 475 store and they are all currently independently owned.
When it comes to firearms, ammunition, reloading supplies etc the corp takes a "hands off" approach for the most part. Since all of these items/components MAY require different licencing requirements, not only on a province by province but sometimes county by county basis, they leave it to the dealer of any given store to decide if they will carry some, all or none of what is potentially available.
If a store chooses to carry then the corp does assist in the application process for whatever licences are needed and they have negotiated with many suppliers/wholesalers who are "pre-approved" to deal with at the individual store level.
If an individual store wants to deal with a supplier "outside" of the "approved list" then there is a rigorous process that can take weeks or months to get corporate approval and then that approval only lasts for a year period.
Because of that, even though there may be rounds available directly from Hornady or powder from ABC powder company, because "neither" is on the "approved list", us at the individual store can not go out and buy from them (unless we go through the process to get them "locally approved" for the one year period).
So while I have had both smokeless powder and black powder subs "on order" for almost a year now, the corporate supplier has been unable to fill the order and they sit there on "back order". My market for such is currently not large enough to jump through all the hoops required to get approval to buy from another source - some other stores may have taken that route.
And I do see why some stores are reluctant to get into the firearms business. The licence to sell process takes about a year, you require the "approved" fixtures to display the rifles/shotguns to meet the safe storage in a retail establishment requirements (which run nearly 1K for each dozen rifles that you want to display, plus a dedicated lock-up in the warehouse for firearms/ammunition only) and then you have to ensure you have enough staff with, minimally, PAL's, to handle, receive and sell the product. If you don't already have hunters and/or gun owners on staff then there is the process of getting them on the course, and paying for their PALs (a minimum wage employee is not expected to chuck 150 bucks for a course and the cost of a PAL, so the store eats that cost as well).
So if owner Bob at Canadian Tire in Butt Nowhere decided "today" that he would like to carry guns, perhaps by the fall of 2016 he would be able to sell the first rifle. Many don't look that far out on the horizon.
It took three of us four years to convince our owner that firearms were worth carrying and we had to do all the leg work to make it happen.
