The CYVR feed equipment is in the midst of a move and will be intermittent or down for a week or two, at a minimum.
The Vancouver Center RCAG for 134.800, 124.075, 134.400, 133.700, 135.325 are all located near the YVR airport, should get good controller reception on all of them. Any chance this new location can accommodate an extra radio or two to cover these frequencies ?
