Thanks to you two.
I've moved it to species page since L. affinis is most likely.

Liodessus
Most likely L. affinis, based on range alone; a nearly identical species, L. noviaffinis also occurs in the east but is more widespread down south (the only records for that species in Canada were in Nova Scotia). Other than that, they can only be reliably separated via examination of male genitalia.
