It's amazing how often I encounter similar situations during consulting. The problem is always the same: Do your ISP research BEFORE you buy a house (residential comment) or BEFORE you choose/rent your biz premises (business comment), because once you're outside of primary Shaw and MTS territory, you're screwed.
"Oh, but the price of the premises was so good .....". Yeah well, if that was more important to you than good Internet, then you'll have to live with it now.
Choosing a proper Internet location (if needed) is just as integral as choosing close schools, bus routes, grocery stores, etc.
