LF: A good pool in north york or markham area

[acinomy]

I am a girl and I only choose to lane swimming over anything else as some sort of workout. But I am having trouble finding a pool that can allow me to swimming right after work. (5pm tp 6pm) Because I hate to have to go home and do whatever and wait until 8pm and leave the house again. Now I know that Gyms often have swimming pool open for lane swim (and I've hear that YMCA north york has a very good pool). But I don't want to pay for everything and only goes for their pool. So everybody, do you think you guy can help me out. Maybe you'll know something that is useful to me.

Thanks Guys
Acinomy

Centinnial in Markham (McCowan & Bullock) just rennovated. Outside looks nice, not sure what they did with the pool.
