For those of you in other parts of Canada, London Drugs is prominent retailer in the west - especially BC. It's almost a department store, selling computers, tech, even prescription glasses and insurance. This indefinite, chain-wide closure due to cybersecurity is concerning.

Iconic western Canadian retailer London Drugs has confirmed it's stores were shut down today due to a 'cybersecurity incident.' LD says it 'immediately undertook countermeasures ... to assist with containment.' It doesn't believe customer data was affected.

2 great topics on Cross Country Checkup this afternoon. First 90 mins: plastics. Do you care about how much you use? How can we use less? Last 30 minutes: our AMA on coffee and energy drinks and your health. How much is too much? (or, for me on Sundays, not enough🙂?).

Your Checkup preview: Are you concerned about the amount plastics you use? What's the best way to reduce the plastics going into the environment? Call tomorrow, go to cbc.ca/aircheck or reply here.
