Archaeologists work on downtown graves

Graves have been found in Place du Canada although it isn’t really news that the area was used as a cemetery years ago.

But the writer handwaves an issue we’ve discussed here before: In the 1860s, most of the bodies at the St. Antoine Cemetery were moved [...] but the exhumations were halted abruptly in 1871 over public fears — unfounded — that raising the dead would mean raising and rekindling some of the deadly epidemics.

As recently as 2010, when Marguerite d’Youville’s remains were moved from the Grey Nuns’ mother house by Concordia, 275 other nuns were left undisturbed because of such danger – these nuns had often worked as hospital nurses during the era: Le ministère de la Santé n’a pas voulu qu’il y ait exhumation parce que certaines des religieuses sont mortes de maladie contagieuse, comme la petite vérole, explique soeur Fournier. Avant de céder l’immeuble à l’Université Concordia, la communauté devait faire couler une dalle de béton sur les tombeaux. Ce qui a été fait il y a quelques mois. «C’était une condition de la vente, résume soeur Fournier, pour éviter les risques de contamination si, par exemple, les ouvriers avaient un jour à aller réparer un dégât d’eau dans la crypte.»

Anyone know what the facts are here? Should we dig ‘em up, or seal ‘em in forever? I asked the question on Metafilter a couple of years ago and some of the responses were interesting, but it seems you can’t categorically rule out the risk.
