Canon has always charged CPS members for loan gear, Nikon has never charged for the gear. In Canada Canon used to be really great to deal with, back in the mid 1980's then it slowly started to fall apart, a lot of the problems started with the pro reps they have used, some have been outstanding and willing to help out, others would treat the loan pool like it was their own gear, one of them would show up at the Toronto Indy car race with and the new Canon gear, and yet when the pros tried to get gear for the same event he would say it was all out, because he wanted to shoot the race himself. He eventually got the boot after a couple of years. I have been dealing with the Nikon pro rep here in Canada and he has been one of the best people I've ever worked with. I use Canon, and yet he loans me what ever Nikon gear I ask for, has been for a few years now. Canon seems to be more interested in the amateur market now.
Canadian Press switched to Nikon last year, a lot had to do with the quality of service.
