An association of grandparents in Nova Scotia is demanding the provincial government give them legal rights to see their grandchildren.

Lizelle Brown, a 79-year-old Bible Hill woman, is a member of the Grandparents Rights for Nova Scotia Association. The group plans to protest in front of the provincial legislature on Thursday.

Brown said right now, grandparents have little or no right to have any contact with grandchildren.

"We are not asking for custody," she told CBC News.

"Just to be able to see them, to hold them, to give them the unconditional love that we have for them."

Brown said she raised her granddaughter, who moved away when she was 15 years old. Now, that granddaughter has two children of her own.

Brown said she was close to her great-grandchildren until her relationship with their mother soured three years ago.

"I miss them," she said.

"I don't think I've ever raised my voice to them and they were always so respectful and loving. We had a very close relationship."

Brown said she hasn't seen her great-granddaughter in several years, and only saw her great-grandson by chance.

"He was getting off the school bus and I stopped and he got in the car. He hugged me and we talked for a few minutes," she said.

A week after that encounter, Brown said she received a message from her granddaughter demanding she cease contact with the children.

She believes there will be repercussions from her granddaughter by going public with her story and protesting, but Brown said she just wants contact with her great-grandchildren.

"I don't think that's too much to ask," she said.
