Good morning, Canada!

It's Friday and CTV News has five things you need to know before kicking off your weekend: Tom Mulcair faces continued pressure ahead of a NDP convention; health officials are investigating if the Zika virus has been sexually transmitted in Canada; the number of Albertans collecting employment insurance has risen; no other cases of skin infection have been found in Kashechewan; and the Rolling Stones are set to play a historic concert in Cuba.

1. Vote of confidence: Two weeks before an NDP convention that will include a vote on Tom Mulcair’s leadership, party president Rebecca Blaikie says he doesn’t necessarily need 70 per cent support to keep the top job. "A number under 70 does not force him to leave, no," she told Power Play.

2. Zika in Canada: Saskatchewan health officials are investigating a possible case of Zika infection that may have been transmitted through sexual activity in Canada, one of the province's top health officials says.

3. EI rising: The number of Albertans collecting employment insurance has risen 91 per cent since January 2015, according to the latest data from Statistics Canada.

4. Social emergency: One of the three doctors who flew to a remote northern Ontario community to investigate reports of dozens of serious skin infections says the team has examined 51 people and found no other cases. Three children from the Kashechewan First Nation have been airlifted out for treatment.

5. Stones in Cuba: The Rolling Stones will be making history with a free performance in Cuba today. The group's music was banned in the country from the 1960s to the 1980s, forcing Cubans to listen to their music in secret.
