I also had the same problem. I am the principal applicant and i am here in canada since 2009. I didnot send orginal experience certificates as it was hard for me to get everything from back home. So i send a notarized copy of the experience letter with a letter of explanation.
Just sharing my experience....................it's up to you
You are absolutely right Ane,
When Principal Applicant can prove her/his experience provide a written explanation and any documentation (i.e. employment contracts, work descriptions, performance appraisals describing job duties) that would support your claim to such employment and provide the information ............ the coapplicant also can do it by a written explanation.
Read the BUFFALO VO check list... string...
For the principal applicant:
•original and up-to-date letters of reference from your past and current employers for the past 10 years.

For the accompanying spouse or common-law partner:
•original and up-to-date letters of reference, including all details as specified above, in respect of any employment in Canada under a work permit.
