In that case, there is nothing you can do...getting married and landing as single. I'm sure even at the airport of landing u still said single.
The CIC officer had suggested you land b4 getting married, but it seems u decided to do the opposite.
The law is clear on this:
Subsection 117(9)(d) of the Immigration and Refugee Protection Regulations, states that, a foreign national shall not be considered a member of the family class by virtue of their relationship to a sponsor if, subject to subsection (10), the sponsor previously made an application for permanent residence and became a permanent resident and, at the time of that application, the foreign national was a non-accompanying family member of the sponsor and was not examined.
