Former immigration minister Chris Alexander is expected to join the race for the federal Conservative leadership.
A source with close knowledge of the race confirms Alexander is gathering the necessary signatures and financial support and building a team for a run.
The source says his campaign is expected to focus on foreign policy and the economy.
Alexander served as Immigration Minister under former PM Stephen Harper.
Alexander became embroiled in controversy during last year’s election campaign amid questions about the government’s handling of the Syrian refugee crisis.
He was also criticized for promising, along with then-labour minister Kellie Leitch, to create a telephone tip line to report so-called “barbaric cultural practices.”
