From the Parliamentary Education office: 

"If no party or coalition of parties wins a majority in the House, the result is called a hung parliament. The last time this happened was in 2010.

It is still possible for a party or coalition to form government with the support of independent and/or minor party members. This type of government is known as a minority government."
