There's a figure 8 boutique at the U of O sports complex.
Now...you are asking where to sharpen, but do you want it done properly? That's a whole other issue. I lived downtown and there's not a place that sharpens well in the downtown core. If you can drive to other areas I have plenty of good recommendations.
The best skate sharpenings Ive gotten have been from the guy at Minto Arena...he takes his time and does a really good job
I agree 100 per cent. He's the best. I bought my last pair of skates at valiquette and figured I'd get them sharpened while I was there. It was the worst cut I've ever had. I could hardly stay on my feet. I was playing at Minto so I took them straight to him and he used his measuring device. He looked at me and asked if I had just tried playing on them. I said, "yes." He replied, "How did you stand up." "I didn't," I said. He fixed them and it was like night and day. I haven't played at Minto in a year, which was not coincidentally my last sharpening. I badly need it done, but haven't had the chance to drive out there.
The point of my rambling is that you should go to Minto.
I play at the Minto too...the guy is one of the best, but very unreliable when it comes to actually being there at the hours he has posted!
There's a couple places in Barrhaven that are very good too. Overtime Sports Repair and Mega City Promotions on Greenbank Rd. in Barrhaven. The guys used to own a Houle sports and he does an excellent job.
