The article is somewhat misleading when it states: "If you received eligible pension income in 2016 (sorry, but Canada Pension Plan benefits don’t qualify) you may be able to report up to one half of that income on your spouse’s tax return."  In fact, CPP benefits can be "split" with a spouse, up to 50%, through a process called "assignment"( this does have to be done in advance and can't be done retroactively for 2016).  The individual receiving CPP must contact Service Canada and request it. The "splitting" will then be reflected in the monthly CPP payments.  Here are two links with further info:
