This study examines entry strategies in the Canadian wireless discount market. Analysis was mainly focused on the incumbents' strategic choices when faced with the threat of sequential entry. The main model used is Fudenberg and Tirole's taxonomy of business strategies that is studied in the context of multimarket contact and when entry deterrence might be considered as a public good. The core of the analysis is done with two interconnected two stage games. It is argued that Fido, Solo and Virgin adopted a Puppy Dog strategy to face Koodo's entry, then might have aligned with their new competitor and switched to a Top Dog attitude when faced with the threat of a second round of market entries.
