Federal cabinet retreat, Telegram CEO arrested, E-bike paramedics and more

The federal Liberal cabinet retreat is underway in Halifax. The gathering kicked off with an announcement on housing, as the Trudeau government tries to turn things around after a challenging summer of dismal polling and internal conflict. Also: The founder of the social media platform Telegram has been arrested in France. Police say the lack of moderators on the app is allowing criminal activity to go unchecked. Plus: A new program in Halifax is helping paramedics respond quickly on the city's busy waterfront - using e-bikes.
