I understand Superformance is available in Canada again. See the post at
Kirkhams in Canada. where 'Mark IV' posted the following on 2014-07-31:
"Actually we have gotten Transport Canada approval for our "Superformance by Riverside" starter kits. The Superformance factory (Hi Tech Automotive) will produce a special, TC approved "starter kit" for import into Canada. This is not available elsewhere and only via us and our Canadian agent."
