Thank you for the question.
My comment about long leave periods—anywhere from nine months and longer—at a lower rate of replacement, as we currently have, was that it has been shown to have negative impacts on women's employment. Use-it-or-lose-it leave, or designated paternity or second-partner leave, has at its core the idea of gender equality and the idea that it encourages men, in most cases, to have a greater role in child care as it enables women to get back into the labour force. The two have two different effects.
And yes, I would certainly be in favour of paternity leave.
