Telus and Shaw provide the hotspots for free to the business owner. They require a signed agreement to keep the equipment in place for some period of time (1yr to 3yr). Generally speaking they do not pay but you are supposedly getting a marketing benefit. That is not to say that they have not paid some people for access to place a hotspot. I do know of cases where they paid for what they thought was a preferred/popular location but it's still a small amount. Those would be cases like where they put coverage in a popular venue and then pay something like $40 per hotspot a year but thats kind of a break even price to compensate for power and employee time arranging installation and maintenance access. Telus/Shaw will list your location on their hotspot list, and you get some window stickers, counter cards, brochures, etc to advertise that your business has the hotspot. So if you want them to pay you, don't ask for any more than $40 per year each as that's about the max even in a good public spot like a stadium or mall.
There is a request list they can submit your info through if you want to volunteer the business. But I think they only look at this list if they have a general area in mind and do not have a tenant in the area they have dealt with before.
Generally though, the clients who got these installed were approached by Shaw asking them if they would like to participate. In a strip mall where there were big national chains, mom an pop stores, or a regional franchise store they went to the regional franchise store first. The mom and pop stores would be a little harder to explain things over and over again each time, the giant national chains were too hard to get permissions, but the local franchise was easier for them to deal with as they likely have a few dozen locations that would be good candidates but they are not so large that they had trouble finding someone to deal with. (Starbucks, McDonalds, Tim Hortons, etc already have their own deals in place for wifi so the big chains likely do their own thing anyhow)
