Transport Canada reply....
This is what I received from Transport Canada today:
?-----------------
The process for application for Gross Weight Increase is as follows:
1. Make full and complete application which will include: Application for flight permit (TC form 24-0044) for purpose of conducting climb test, Fee payment for flight permit, provide TC with adequate substantiating documentation to justify a gross weight increase.
2. When Flight permit is issued, fly successful climb test and provide TC with satisfactory and complete Amateur Built Climb Test Report (TC form 24-0091).
3. Make application for issuance of new Flight Authority (TC form 24-0043) and pay fee for new flight authority.
4. Aircraft inspection by TC.
5. Relinquish superseded flight authority to TC.
All forms are easily accessible by simple Google search of the Transport Canada web page. I have included a link to all appropriate forms here:

Fees also are readily available on-line in the CARS at CAR104 schedule VI and are as follows:
Issuance of a specific purpose flight permit, $45.
Approval of an amendment to the operations specifications set out in the flight authority?amateur built, $35.
You may pay these fees in person at the Ottawa TCC or by telephone at 1-800-305-2059.
NOTE: Inspector will require proof of fee payment for each application to be processed.
As far as substantiating documentation is concerned, we don?t have any conclusive list of expected items as all Amateur built aircraft are unique by their build standard. Citing that a similar aircraft on the registry have similar max gross weights is not acceptable as your build circumstances will not necessarily be consistent with those of the other similar aircraft. (i.e., the other aircraft may have heavier wing struts installed, etc.) It?s not like with Type Certified aircraft, where every aircraft of that type was built and is maintained to a consistent build standard.
With that, I would expect an applicant to provide loading calculations, weight and balance calculations that show aircraft in it?s current state (in any configuration) falls within the kit manufactures specified flight envelope.
Additionally, any modifications made to the structure of the aircraft in order to prepare the airframe to accommodate the extra weight and to what standard those mods were completed, with supporting documentation. Often, the kit manufacturer also has documentation specifying alternate max gross weights or other similar models/model upgrades that can be incorporated into the design and build of your aircraft to help substantiate your request.

Does anyone have any document from Vans that would qualify as "substantiating documentation" ?
