Given that no other Canadian news outlet is reporting this massacre by 'Syrian rebels',  a name which is now synonymous with ISIL ideals, financed by Saudi Arabia and supported and armed by the US and NATO nations, it must have been with some degree of reluctance that 'The Globe and Mail' published even the scantest of reports.  The latest count is 156 dead, of whom 68 were children.  As others have noted, none of the Western nations have issued any condemnation, despite the death toll, likely because the victims were Shia Muslims, loyal to the Assad regime, and hence deadly enemies of Wahhabi Islam, the religious 'power behind the throne' in Saudi Arabia.  
Western involvement in Syria, largely at the behest of the Saudis, with considerable encouragement from Turkey, will undoubtedly result in Syria becoming the same cesspit that enforced regime change has created in Iraq and Libya, with the orchestrated 'invasion' of Western nation by Muslim 'refugees' becoming even stronger.
