Strapped for time but looking for a quick morning update? Well, we've got it.

Here are the 5 things you need to know this Tuesday: the Assembly of First Nations general assembly gets underway in Montreal; eurozone leaders meet for more talks in the wake of the Greek referendum; a Calgary man says he regrets nothing after making an unusual entrance to the Calgary Stampede; a new study says a brisk walk can help fight heart failure in seniors; and a toddler was handed his first parking ticket by Halifax police.

Plus, for "Tech Tuesday," those photos you share on Instagram are about to get a whole lot clearer.

1. AFN Assembly: The Assembly of First Nations general assembly gets underway in Montreal with opposition leaders expected to deliver a stack of campaign style commitments. Liberal leader Justin Trudeau is poised to promise improved funding for First Nations education and call for an overhaul of the relationship between First Nations and the government.

2. Brussels summit: Greek PM Alexis Tsipras and other eurozone leaders are meeting in Brussels today to discuss the fallout from the weekend referendum. European Commission President Jean-Claude Juncker has refuted suggestions of a quick solution.

3. Scenic view: The Calgary man who soared over the Calgary Stampede grounds in a lawn chair borne by balloons says he has no regrets. Daniel Boria faces one charge of mischief causing danger to life for the stunt.

4. Healthy heart: A new study says those over the age of 65 can significantly cut their risk for heart failure by maintaining an active lifestyle. But you don’t have to hit the gym -- just a brisk walk can help keep your heart in shape.

5. Toddler ticketed: A photo of a Halifax police officer writing a pretend parking ticket for a dismayed 3-year-old boy on a plastic motorbike has been shared by thousands on Facebook. There’s no word on whether the boy will pay the fine with pretend money.

And one more thing for Tech Tuesday:

Images posted and shared on the social network are about to get sharper and clearer. Users will soon be sharing images in 1080p – although they’ll still be square.
