Rail confusion, U.S. Presidential campaign, prepackaged baby food nutrition

If there was optimism that the rail labour dispute was over, it was short lived. Despite the federal government ordering binding arbitration, a new wrench was thrown into the mix. The union representing CN workers issued a strike notice, leaving many to wonder what will happen next.

Also: With national political conventions now over, Republicans and Democrats are trying to hone their political messages as the campaign enters a new phase. Democrats are trying to keep their momentum alive, while Republicans work to win back the spotlight.

Plus: A new study of pre-packaged food for babies and toddlers suggests that many of those products do not meet international standards for nutrition. And some could even have an impact on a child’s development.
