I can't say that it's specifically the case, but in Montreal, there's been an ever increasing number of vacant commercial spaces - seemingly because they know that "eventually" some BigCo will come along and be willing to pay the extremely high rent. As anecdata, there's a corner space on the ground floor of Duluth and St. Laurent that's been vacant for well over a year - maybe even two. It's pricing out smaller businesses, and even though the space is available and empty, it's just unaffordable and priced far above the true market value.
We don't want more A&W's and Starbucks, but that's what eventually happens here. The only places that survive are bars.
