SpeakOut is still the best prepaid deal in Canada for light users.
Rogers charges a 911 fee of up to $1.25 (it varies by province) and Rogers rates are 40 cents per minute for light users who don't use the $20 of airtime each month required to get the 20% Auto Saver discount.
Virgin charges 35 cents/minute, President's Choice gives you a 20 cent/minute rate but requires at least $15 per month in top-ups.
I'm still very happy with SO. No way my family would switch to another service right now.
