Canada Post says there’s a safety concern at Kensington Manor but it’s resuming service Monday. A cockroach infestation at a Toronto Community Housing building has left more than 100 seniors without mail for nearly a month, cutting some off from their pension cheques, bills and doctors’ letters without notice. Two residents, Joseph Quirk and Wayne Youngs, say Canada Post stopped daily mail delivery to Kensington Manor, at 34 Oxford St., in July after all three mail rooms became overrun by the roaches. None of the residents were officially informed of the change, or notified about how they could get their mail in the meantime, they said. Youngs relies on Canada Post for letters about upcoming appointments with medical specialists, but said he only noticed the service disruption when he suddenly stopped getting his usual flyers.
