According to the minister responsible for the city, Jean-François Lisée, the families of 7,000 children under the age of 14 leave Montreal every year to settle in the suburbs.
Lisée has created a committee to address the migration of young families from the island.
The committee will look at strategies and incentives to encourage young families to remain.
"If we succeed, it will mean more life in Montreal, more fiscal base in Montreal, more enrolment in English schools, and keeping the equilibrium of having a majority of francophones on the island," said Lisée.
He said the high cost of buying a home in the city often drives families away, even though they would prefer to stay.The committee could propose a range of measures, including programs to encourage home ownership.
It may also look at other issues that affect the quality of life, such as transportation, education and recreation.
In its search for solutions, the committee will look at what other cities have done to attract young families.
