In limited circumstances it may make sense for a CCPC target to make an s. 89(11) election

In the situation where, for example, a non-resident enters into an agreement to acquire a Canadian-controlled private corporation on September 1 and the agreement closes on December 1, it might be desirable for the target to make an election under s. 89(11) to be considered to not be a CCPC from the commencement of that year. This will have the advantage that it will not have a deemed year end on August 31 of that year (i.e., at the time immediately before that at which it otherwise would have ceased to be a CCPC), so that it will only have one deemed year end (immediately before the acquisition of control on December 1) rather than two.

Although making this election will also apply for small business deduction and LRIP/GRIP purposes, it will not affect the target's ability to claim the enhanced ITC for SR&ED, nor the ability of its shareholders to claim an allowable business investment loss or the capital gains deduction for qualified small business corporation shares.
