No.  The CRA recognizes that many charities need to fundraise in order to be able to have the resources those charities need to fulfill their charitable mission.

In the CRA’s Fundraising Guidance they note:

“The Canada Revenue Agency (CRA) recognizes that registered charities in Canada often depend on charitable donations and other sources of revenue to carry out their charitable works. For many charities, this means that a proportion of their resources will be used for fundraising to support their charitable work. While recognizing the necessity of fundraising, the CRA expects charities to be transparent and to not devote excessive amounts of time and/or resources to fundraising as opposed to fulfilling their charitable purposes.”
