It's Wednesday and CTV News has gathered the day's top stories. Here are the five things you need to know: the Conservatives say Canada needs to protect the women who left the country to join ISIS and raise children with the group; the federal government's anti-ISIS plan is being criticized by opponents; a new study has looked at the impact of fluoride cessation in Calgary; a B.C. couple has launched a lawsuit over a fertility drug; and Ottawa was hit with a record-breaking amount of snow.

1. Caliphate cubs: Interim Conservative leader Rona Ambrose says Canada needs to protect the women who have travelled to Syria and Iraq to raise children with ISIS fighters. She said the women and their children are "at risk" and "still Canadian."

2. Health affected: A new report has found that fluoride cessation in Calgary has negatively impacted children's dental health, adding fresh fuel to the ongoing debate over fluoridation. The study compared data from dental records of more than 5,000 Grade 2 students in Calgary and Edmonton.

3. Bombardier job cuts: Bombardier has announced that it is cutting 7,000 positions over the next two years. The company says the losses will be offset by hiring in certain areas.

4. Lawsuit launched: A British Columbia couple has launched a class-action lawsuit against Ferring Pharmaceuticals after certain batches of the drug were recalled over potency last year. Amanda and Joep Olthuis say the ineffective batch dashed their hopes of having children.

5. Winter wallop: Ottawa got hit with a record-smashing 51 centimetres of snow in a single day, burying the nation’s capital. Official measurements are taken at the city’s airport.
