Financial planning for mat leave

Pamela • Expecting baby #1 (it's a boy!) Jan 18, 2015 after 18 months TTC with PCOS and 2 rounds of clomid.
Anyone have any tips for planning financially for mat leave?
​I'm in Canada so I know I'm very fortunate to be able to take a year off and qualitlfy for maternity leave benefits, but my husband is a full time student so thinking ahead to the finances is making me nervous.  I figure the earlier we can decrease our spending and increase our savings the better!
