Worldwide grief over the image of a drowned Syrian toddler in Turkey focused on Canada’s shores Thursday as the tangled story of the Kurdi family’s desperate flight unfolded. The two boys and their mother were among 12 migrants drowned when two boats carrying them from the Turkish coast to the Greek island of Kos capsized.

Prime Minister Stephen Harper defended his government Thursday, saying Canada has already accepted 2,300 Syrian refugees since 2013, supports the military mission to bring peace to Syria, and been the “most generous” donor of humanitarian aid while “most countries are simply not doing their part and they need to do more.”
