PTE.V PTEFF I've been invested for a while. Huge market and they're the main company. There is a government regulation starting in 2018 to require their products in government run multi family housing projects that should boost growth even more.
Pioneering announced a financing a few days ago at C$1.10. Never fell to that level, but did drop to C$1.18 on the day of announcement.
Here is Q1 results. Solid increases in sales and profits. Earned .02eps so PTE.v is not cheap on a P/E basis but I think it's at the beginning of a long growth curve.
