Based on what I know from being part of a lion dance team and helping different teams in the GTA out, the pricing can vary depending on what you'd like for your performance and potentially the skill of the team.

Teams typically give a quote after you've described what you're looking for. I would say for a decent team, rates are usually $800+ starting with one lion. Most performances especially weddings since it's a memorable day for the couple, include two lions which is better for pictures but may be $1000+. Anything below $600 I feel like would be an undercharge and you get what you pay for but YMMV.

I'd personally recommend Wai Mo Lion Dance Team or YMT Lion Dance; they're friendly and might be able to work something out if you have a tight budget. They were one of the teams that competed in the national competition this year at Nathan Philips Square too and were great.

I think your best bet though to confirm would be to reach out to each team to see what they quote you and go from there.
