Tuesday Morning Links

This and that for your Tuesday reading.

- Meanwhile, Consumer Reports finds that dark chocolate is rife with dangerous levels of cadmium and lead - meaning that a product often promoted as a healthier alternative may be smuggling harmful metals into people's bodies.   

- Alex Cooke reports on Halifax's failure to ensure that unhoused people have access to safe accommodations as winter endangers their lives. And Colin Butler points out how encampments made more precarious by the threat of police removal are at particular risk of having concealed fires burn out of control. 

- The Energy Mix discusses how oil is headed down the same path toward obsolescence as telephone landlines due to the increasing availability of superior alternatives. 

- Austin Grabash reports on the private religious schools which insisted on censored tours of the Canadian Museum of Human Rights to avoid any acknowledgement of the rights of LGBTQ people. And Feo Snagovsky discusses how the UCP and Saskatchewan Party are causing real damage to Canadian federalism with their performative posturing about sovereignty.
