On the Other Side(s) of 150 explores the different literary, historical and cultural legacies of Canada’s sesquicentennial celebrations. It asks vital questions about the ways that histories and stories have been suppressed and invites consideration about what happens once a commemorative moment has passed. Like a Cubist painting, this modality offers a critical strategy by which also to approach the volume as dismantling, reassembling, and re-enacting existing commemorative tropes; as offering multiple, conditional, and contingent viewpoints that unfold over time; and as generating a broader (although far from being comprehensive) range of counter-memorial performances. The chapters in this volume are thus provisional, interconnected, and adaptive: they offer critical assemblages by which to approach commemorative narratives or showcase lacunae therein; by which to return to and intervene in ongoing readings of the past from the present moment; and by which not necessarily to resolve, but rather to understand the troubled and troubling narratives of the present moment. Contributors propose that these preoccupations are not a means of turning away from present concerns, but rather a means of grappling with how the past informs or is shaped to inform them; and how such concerns are defined by immediate social contexts and networks.
