The Cana­di­an Light­source is a 2.9 GeV 3rd gen­er­a­tion light­source in Saska­toon, Cana­da. The lat­est ex­pan­sion of op­er­a­tions in­cludes adding 4 in­ser­tion de­vices in 2 straight sec­tions. These de­vices will in­clude a hy­brid per­ma­nent mag­net wig­gler, an in-vac­u­um un­du­la­tor and 2 AP­PLE-II type un­du­la­tors. The 4 m long el­lip­ti­cal AP­PLE-II IDs will cover over­lap­ping pho­ton en­er­gy ranges of 15-200eV and 200-1000eV. These de­vices will be in­stalled ad­ja­cent to one an­oth­er in the same straight with the mag­net ar­rays mount­ed on one sup­port struc­ture and a hor­i­zon­tal trans­la­tion sys­tem to allow users to se­lect one de­vice at a time for use on a sin­gle beam­line. The 2nd straight will in­clude the hy­brid wig­gler and in-vac­u­um un­du­la­tor in a 3 mag­net chi­cane. The wig­gler is de­signed to sup­ply pho­tons for a cen­ter beam­line and a side beam­line ac­cept­ing ra­di­a­tion 5 mrad off of the cen­ter­line of the ra­di­a­tion fan. The crit­i­cal en­er­gy of pho­tons emit­ted of the side­line are >90% of the crit­i­cal en­er­gy on the cen­ter­line. An 8 mrad cen­ter chi­cane mag­net sep­a­rates the pho­tons of the un­du­la­tor from the wig­gler beam­lines al­low­ing for 3 beam­lines op­er­at­ing with 2 IDs in a sin­gle straight sec­tion.
