In that case I would suggest that Olive Garden Canada didn't "go out of business" (i.e. naturally through business dying off), but was killed intentionally.
It didn't die as a result of failure on its own part.
There is also a difference between a restaurant and a chain of restaurants - in any case the US component survived, so I would say that the (overall) business didn't "die off".
