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

Here are the five things you need to know this Tuesday: the New Hampshire primary has kicked off, with both Donald Trump and Bernie Sanders hoping for wins; two trains have collided in southern Germany injuring over 150; the RCMP are due to release an update on efforts to implement recommendations following the Moncton shootings; retired Maj.-Gen. David Fraser discusses Canada's changing role in the fight against ISIS; and a look at how much a relationship from first date to marriage can cost.

1. New Hampshire primary: Registered Democrats and Republicans are choosing their preferred presidential candidates today, but a handful of people voted hours ago, carrying on a nearly 60-year tradition that put their tiny town on the map. Here’s the story behind the village of Dixville Notch. 

2. Head-on collision: A head-on crash involving two trains in southern Germany has left at least eight dead and roughly 150 people injured. A police spokesman said several wagons had overturned and it took rescuers hours to reach some of those injured.

3. Moncton shootings: The RCMP is set to give an update on its efforts to implement recommendations stemming from the shooting deaths of three officers in Moncton, N.B. in June 2014.

4. Fight against ISIS: CTV News Chief Anchor and Senior Editor Lisa LaFlamme spoke with retired Maj.-Gen. David Fraser on Canada’s changing role in the coalition fight against the Islamic State, and whether tripling the number of trainers will increase the risk for Canadians on the ground.

5. Breaking it down: A study has examined just how much your relationship with a loved one will cost you. From dates to the costs of the big day, it doesn't make for especially happy reading.
