Yeh, my Mom's retirement home in Brampton called yesterday to say they were restricting visitors until further notice. No cases yet, just to prevent any incoming bugs.
They were hit pretty hard with that Norfolk (sp?) flu late last year, 50/130 residents had it plus some of the staff.
Elderly tend to have less resistance, particularly if suffering from other ailments, and the close quarters/common dining area helps anything spread like wildfire.
