The Victoria Day weekend kept burning along Sunday, bringing with it the good and bad sides of hot weather.

Temperatures cracked the 30 C mark and a smog advisory was issued in Ottawa Sunday, both for the first time this year.

The temperature sent families to Ottawa's just-opened splash pads so kids could cool off.

"I think it's really fun, and it's nice and warm," said Melanie Phillips. "A lot warmer than it is in Calgary."

"They asked if we need to pack a bathing suit, I said ‘Yup, we probably don't need it but bring it,'" said Sean Phillips, who said it was snowing when they left their hometown.

Ottawa's beaches remain closed until June 16, but that wasn't stopping people from hitting the water for the second straight day.

"We're just following the lead of everyone else, it looks like it's okay," said Trish Charles.

"That's our little tent over there, so when they get too hot, it's here or the tent," said Neil Wilson.

"After this, it will be ice cream," added Angie Wilson.

On the downside, west Ottawa's famous Hintonburger restaurant tweeted it had to close early because of problems with its air conditioning.

Ottawa paramedics said as of 5 p.m. they hadn't received any heat-related calls.

We don't want people suffering from heat exhaustion or heat stroke," said Paul Morneau with the Ottawa Paramedic Service. "We always respond to these types of calls on days like this."

Paramedics also said to be wary of the fact that water, especially when it's deep, can still be quite cold.

Monday's forecast shows a high of 28 C with a mix of sun and cloud.
