Certainly not. It MIGHT destroy computers and harddrives, sure. But it being Govt, they have significant standards for their computers and data storage... it would shock me to no end if they didn't have:
-backup drives in another province, say Quebec or Saskatchewan.
-third party commercial ultra-secure backup, say like IronMountain in Coquitlam.
-paper records, generated by automatic printing, as a backup in case the whole system crashes hard.
Besides, if an EMP device (even non-nuke versions) were ever actually used, I'd bet a stack of cash that we'd have much bigger problems than whether or not our govt has records of what we own...MUCH bigger problems! Problems like the "sh!t has hit the fan"...

Basic SKS, 12gauge pump or semi, and a .22 like the 1022 for small game food
